Subpart A—General
§ 172.1
Purpose and scope.
This part lists and classifies those
materials which the Department has
designated as hazardous materials for
purposes of transportation and pre-
scribes the requirements for shipping
papers, package marking, labeling, and
transport vehicle placarding applicable
to the shipment and transportation of
those hazardous materials.

§ 172.101
§ 172.3
Applicability.
(a) This part applies to—
(1) Each person who offers a haz-
ardous material for transportation, and
(2) Each carrier by air, highway, rail,
or water who transports a hazardous
material.
(b) When a person, other than one of
those provided for in paragraph (a) of
this section, performs a packaging la-
beling or marking function required by
this part, that person shall perform the
function in accordance with this part.
[Amdt. 172–29, 41 FR 15996, Apr. 15, 1976, as

Subpart B—Table of Hazardous
Materials and Special Provisions
§ 172.101
Purpose and use of haz-
ardous materials table.
(a) The Hazardous Materials Table
(Table) in this section designates the
materials listed therein as hazardous
materials for the purpose of transpor-
tation of those materials. For each
listed material, the Table identifies the
hazard class or specifies that the mate-
rial is forbidden in transportation, and
gives the proper shipping name or di-
rects the user to the preferred proper
shipping name. In addition, the Table
specifies or references requirements in
this subchapter pertaining to labeling,
packaging, quantity limits aboard air-
craft and stowage of hazardous mate-
rials aboard vessels.
(b)
Column 1: Symbols.
Column 1 of the
Table contains six symbols (‘‘ + ’’, ‘‘A’’,
‘‘D’’, ‘‘G’’, ‘‘I’’ and ‘‘W’’) as follows:
(1) The plus (+) sign fixes the proper
shipping name, hazard class and pack-
ing group for that entry without regard
to whether the material meets the defi-
nition of that class, packing group or
any other hazard class definition. When
the plus sign is assigned to a proper
shipping name in Column (1) of the
§ 172.101 Table, it means that the mate-
rial is known to pose a risk to humans.
When a plus sign is assigned to mix-
tures or solutions containing a mate-
rial where the hazard to humans is sig-
nificantly different from that of the
pure material or where no hazard to
humans is posed, the material may be
described using an alternative shipping
name that represents the hazards posed
by the material. An appropriate alter-
nate proper shipping name and hazard
class may be authorized by the Asso-
ciate Administrator.
(2) The letter ‘‘A’’ denotes a material
that is subject to the requirements of
this subchapter only when offered or
intended for transportation by aircraft,
unless the material is a hazardous sub-
stance or a hazardous waste. A ship-
ping description entry preceded by an
‘‘A’’ may be used to describe a material
for other modes of transportation pro-
vided all applicable requirements for
the entry are met.
(3) The letter ‘‘D’’ identifies proper
shipping names which are appropriate
for describing materials for domestic
transportation but may be inappro-
priate for international transportation
under the provisions of international
regulations (e.g., IMO, ICAO). An alter-
nate proper shipping name may be se-
lected when either domestic or inter-
national transportation is involved.
(4) The letter ‘‘G’’ identifies proper
shipping names for which one or more
technical names of the hazardous ma-
terial must be entered in parentheses,
in association with the basic descrip-
tion. (See § 172.203(k).)
(5) The letter ‘‘I’’ identifies proper
shipping names which are appropriate
for describing materials in inter-
national transportation. An alternate
proper shipping name may be selected
when only domestic transportation is
involved.
(6) The letter ‘‘W’’ denotes a material
that is subject to the requirements of
this subchapter only when offered or
intended for transportation by vessel,
unless the material is a hazardous sub-
stance or a hazardous waste. A ship-
ping description entry preceded by a
‘‘W’’ may be used to describe a mate-
rial for other modes of transportation
provided all applicable requirements
for the entry are met.
(c)
Column 2: Hazardous materials de-
scriptions and proper shipping names.
Column 2 lists the hazardous materials
descriptions and proper shipping names
of materials designated as hazardous
materials. Modification of a proper
shipping name may otherwise be re-
quired or authorized by this section.
Proper shipping names are limited to
154
49 CFR Ch. I (10–1–23 Edition)
§ 172.101
those shown in Roman type (not
italics).
(1) Proper shipping names may be
used in the singular or plural and in ei-
ther capital or lower case letters.
Words may be alternatively spelled in
the same manner as they appear in the
ICAO Technical Instructions or the
IMDG Code. For example ‘‘aluminum’’
may be spelled ‘‘aluminium’’ and ‘‘sul-
fur’’ may be spelled ‘‘sulphur’’. How-
ever, the word ‘‘inflammable’’ may not
be used in place of the word ‘‘flam-
mable’’.
(2) Punctuation marks and words in
italics are not part of the proper ship-
ping name, but may be used in addition
to the proper shipping name. The word
‘‘or’’ in italics indicates that there is a
choice of terms in the sequence that
may alternately be used as the proper
shipping name or as part of the proper
shipping name, as appropriate. For ex-
ample, for the hazardous materials de-
scription ‘‘Carbon dioxide, solid or Dry
ice’’ either ‘‘Carbon dioxide, solid’’ or
‘‘Dry ice’’ may be used as the proper
shipping name; and for the hazardous
materials description ‘‘Articles, pres-
surized pneumatic or hydraulic,’’ ei-
ther ‘‘Articles, pressurized pneumatic’’
or ‘‘Articles, pressurized hydraulic’’
may be used as the proper shipping
name.
(3) The word ‘‘poison’’ or ‘‘poisonous’’
may be used interchangeably with the
word ‘‘toxic’’ when only domestic
transportation is involved. The abbre-
viation ‘‘n.o.i.’’ or ‘‘n.o.i.b.n.’’ may be
used interchangeably with ‘‘n.o.s.’’.
(4) Except for hazardous wastes, when
qualifying words are used as part of the
proper shipping name, their sequence
in the package markings and shipping
paper description is optional. However,
the entry in the Table reflects the pre-
ferred sequence.
(5) When one entry references an-
other entry by use of the word ‘‘see’’, if
both names are in Roman type, either
name may be used as the proper ship-
ping name (e.g., Ethyl alcohol,
see
Eth-
anol).
(6) When a proper shipping name in-
cludes a concentration range as part of
the shipping description, the actual
concentration, if it is within the range
stated, may be used in place of the con-
centration range. For example, an
aqueous solution of hydrogen peroxide
containing 30 percent peroxide may be
described as ‘‘Hydrogen peroxide, aque-
ous solution
with not less than 20 percent
but not more than 40 percent hydrogen
peroxide’’
or ‘‘Hydrogen peroxide, aque-
ous solution
with 30 percent hydrogen
peroxide.
’’ Also, the percent sign (%)
may be used in place of the word ‘‘per-
cent’’ when words in italics containing
the word ‘‘percent’’ are used in addi-
tion to the proper shipping name.
(7) Use of the prefix ‘‘mono’’ is op-
tional in any shipping name, when ap-
propriate. Thus, Iodine monochloride
may be used interchangeably with Io-
dine chloride. In ‘‘Glycerol alpha-
monochlorohydrin’’ the term ‘‘mono’’
is considered a prefix to the term
‘‘chlorohydrin’’ and may be deleted.
(8) Use of the word ‘‘liquid’’ or
‘‘solid’’. The word ‘‘liquid’’ or ‘‘solid’’
may be added to a proper shipping
name when a hazardous material spe-
cifically listed by name may, due to
differing physical states, be a liquid or
solid. When the packaging specified in
Column 8 is inappropriate for the phys-
ical state of the material, the table
provided in paragraph (i)(4) of this sec-
tion should be used to determine the
appropriate packaging section.
(9)
Hazardous wastes.
If the word
‘‘waste’’ is not included in the haz-
ardous material description in Column
2 of the Table, the proper shipping
name for a hazardous waste (as defined
in § 171.8 of this subchapter), shall in-
clude the word ‘‘Waste’’ preceding the
proper shipping name of the material.
For example: Waste acetone.
(10)
Mixtures and solutions.
(i) A mix-
ture or solution meeting the definition
of one or more hazard class that is not
identified specifically by name, com-
prised of a single predominant haz-
ardous material identified in the Table
by technical name and one or more
hazardous and/or non-hazardous mate-
rial, must be described using the proper
shipping name of the hazardous mate-
rial and the qualifying word ‘‘mixture’’
or ‘‘solution’’, as appropriate, unless—
(A) Except as provided in
§ 172.101(i)(4) the packaging specified in
Column 8 is inappropriate to the phys-
ical state of the material;
(B) The shipping description indi-
cates that the proper shipping name
155
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.101
applies only to the pure or technically
pure hazardous material;
(C) The hazard class, packing group,
or subsidiary hazard of the mixture or
solution is different from that specified
for the entry;
(D) There is a significant change in
the measures to be taken in emer-
gencies;
(E) The material is identified by spe-
cial provision in Column 7 of the
§ 172.101 Table as a material poisonous
by inhalation; however, it no longer
meets the definition of poisonous by in-
halation or it falls within a different
hazard zone than that specified in the
special provision; or
(F) The material can be appro-
priately described by a shipping name
that describes its intended application,
such as ‘‘Coating solution’’, ‘‘Extracts,
flavoring’’ or ‘‘Compound, cleaning liq-
uid.’’.
(ii) If one or more of the conditions
in paragraphs (c)(10)(i)(A) through (F)
of this section is satisfied then the
proper shipping name selection process
in (c)(12)(ii) must be used.
(iii) A mixture or solution meeting
the definition of one or more hazard
class that is not identified in the Table
specifically by name, comprised of two
or more hazardous materials in the
same hazard class, must be described
using an appropriate shipping descrip-
tion (e.g., ‘‘Flammable liquid, n.o.s.’’).
The name that most appropriately de-
scribes the material shall be used; e.g.,
an alcohol not listed by its technical
name in the Table shall be described as
‘‘Alcohol, n.o.s.’’ rather than ‘‘Flam-
mable liquid, n.o.s.’’. Some mixtures
may be more appropriately described
according to their application, such as
‘‘Coating solution’’ or ‘‘Extracts, fla-
voring liquid’’ rather than by an n.o.s.
entry. Under the provisions of subparts
C and D of this part, the technical
names of at least two components most
predominately contributing to the haz-
ards of the mixture or solution may be
required in association with the proper
shipping name.
(11) Except for a material subject to
or prohibited by § 173.21, § 173.54,
§ 173.56(d), § 173.56(e), § 173.224(c) or
§ 173.225(b) of this subchapter, a mate-
rial that is considered to be a haz-
ardous waste or a sample of a material
for which the hazard class is uncertain
and must be determined by testing
may be assigned a tentative proper
shipping name, hazard class, identifica-
tion number and packing group, if ap-
plicable, based on the shipper’s ten-
tative determination according to:
(i) Defining criteria in this sub-
chapter;
(ii) The hazard precedence prescribed
in § 173.2a of this subchapter;
(iii) The shipper’s knowledge of the
material;
(iv) In addition to paragraphs
(c)(11)(i) through (iii) of this section,
for a sample of a material other than a
waste, the following must be met:
(A) Except when the word ‘‘Sample’’
already appears in the proper shipping
name, the word ‘‘Sample’’ must appear
as part of the proper shipping name or
in association with the basic descrip-
tion on the shipping paper.
(B) When the proper shipping descrip-
tion for a sample is assigned a ‘‘G’’ in
Column (1) of the § 172.101 Table, and
the primary constituent(s) for which
the tentative classification is based are
not known, the provisions requiring a
technical name for the constituent(s)
do not apply; and
(C) A sample must be transported in
a combination packaging that con-
forms to the requirements of this sub-
chapter that are applicable to the ten-
tative packing group assigned, and
may not exceed a net mass of 2.5 kg (5.5
pounds) per package.
N
OTE TO PARAGRAPH
(c)(11): For the trans-
portation of samples of self-reactive mate-
rials, organic peroxides, explosives or light-
ers,
see
§ 173.224(c)(3), § 173.225(c)(2), § 173.56(d)
or § 173.308(b)(2) of this subchapter, respec-
tively.
(12) Except when the proper shipping
name in the Table is preceded by a plus
(+)—
(i) If it is specifically determined
that a material meets the definition of
a hazard class, packing group or hazard
zone, other than the class, packing
group or hazard zone shown in associa-
tion with the proper shipping name, or
does not meet the defining criteria for
a subsidiary hazard shown in Column 6
of the Table, the material shall be de-
scribed by an appropriate proper ship-
ping name listed in association with
the correct hazard class, packing
156
49 CFR Ch. I (10–1–23 Edition)
§ 172.101
group, hazard zone, or subsidiary haz-
ard for the material.
(ii)
Generic or n.o.s. descriptions.
If an
appropriate technical name is not
shown in the Table, selection of a prop-
er shipping name shall be made from
the generic or n.o.s. descriptions cor-
responding to the specific hazard class,
packing group, hazard zone, or sub-
sidiary hazard, if any, for the material.
The name that most appropriately de-
scribes the material shall be used; e.g.,
an alcohol not listed by its technical
name in the Table shall be described as
‘‘Alcohol, n.o.s.’’ rather than ‘‘Flam-
mable liquid, n.o.s.’’. Some mixtures
may be more appropriately described
according to their application, such as
‘‘Coating solution’’ or ‘‘Extracts, fla-
voring, liquid’’, rather than by an n.o.s.
entry, such as ‘‘Flammable liquid,
n.o.s.’’ It should be noted, however,
that an n.o.s. description as a proper
shipping name may not provide suffi-
cient information for shipping papers
and package markings. Under the pro-
visions of subparts C and D of this part,
the technical name of one or more con-
stituents which makes the product a
hazardous material may be required in
association with the proper shipping
name.
(iii)
Multiple hazard materials.
If a ma-
terial meets the definition of more
than one hazard class, and is not iden-
tified in the Table specifically by name
(e.g., acetyl chloride), the hazard class
of the material shall be determined by
using the precedence specified in
§ 173.2a of this subchapter, and an ap-
propriate shipping description (e.g.,
‘‘Flammable liquid, corrosive n.o.s.’’)
shall be selected as described in para-
graph (c)(12)(ii) of this section.
(iv) If it is specifically determined
that a material is not a forbidden ma-
terial and does not meet the definition
of any hazard class, the material is not
a hazardous material.
(13)
Self-reactive materials and organic
peroxides.
A generic proper shipping
name for a self-reactive material or an
organic peroxide, as listed in Column 2
of the Table, must be selected based on
the material’s technical name and con-
centration, in accordance with the pro-
visions of § 173.224 or § 173.225 of this
subchapter, respectively.
(14) A proper shipping name that de-
scribes all isomers of a material may
be used to identify any isomer of that
material if the isomer meets criteria
for the same hazard class or division,
subsidiary risk(s) and packing group,
unless the isomer is specifically identi-
fied in the Table.
(15) Unless a hydrate is specifically
listed in the Table, a proper shipping
name for the equivalent anhydrous
substance may be used, if the hydrate
meets the same hazard class or divi-
sion, subsidiary risk(s) and packing
group.
(16) Unless it is already included in
the proper shipping name in the
§ 172.101 Table, the qualifying words
‘‘liquid’’ or ‘‘solid’’ may be added in as-
sociation with the proper shipping
name when a hazardous material spe-
cifically listed by name in the § 172.101
Table may, due to the differing phys-
ical states of the various isomers of the
material, be either a liquid or a solid
(for example ‘‘Dinitrotoluenes, liquid’’
and ‘‘Dinitrotoluenes, solid’’). Use of
the words ‘‘liquid’’ or ‘‘solid’’ is subject
to the limitations specified for the use
of the words ‘‘mixture’’ or ‘‘solution’’
in paragraph (c)(10) of this section. The
qualifying word ‘‘molten’’ may be
added in association with the proper
shipping name when a hazardous mate-
rial, which is a solid in accordance
with the definition in § 171.8 of this sub-
chapter, is offered for transportation in
the molten state (for example,
‘‘Alkylphenols, solid, n.o.s., molten’’).
(17) Unless it is already included in
the proper shipping name in the
§ 172.101 Table, the qualifying word
‘‘stabilized’’ may be added in associa-
tion with the proper shipping name, as
appropriate, where without stabiliza-
tion the substance would be forbidden
for transportation according to
§ 173.21(f) of this subchapter.
(d)
Column 3: Hazard class or Division.
Column 3 contains a designation of the
hazard class or division corresponding
to each proper shipping name, or the
word ‘‘Forbidden’’.
(1) A material for which the entry in
this column is ‘‘Forbidden’’ may not be
offered for transportation or trans-
ported. This prohibition does not apply
if the material is diluted, stabilized or
incorporated in a device and it is
157
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.101
classed in accordance with the defini-
tions of hazardous materials contained
in part 173 of this subchapter.
(2) When a reevaluation of test data
or new data indicates a need to modify
the ‘‘Forbidden’’ designation or the
hazard class or packing group specified
for a material specifically identified in
the Table, this data should be sub-
mitted to the Associate Administrator.
(3) A basic description of each hazard
class and the section reference for class
definitions appear in § 173.2 of this sub-
chapter.
(4) Each reference to a Class 3 mate-
rial is modified to read ‘‘Combustible
liquid’’ when that material is reclassi-
fied in accordance with § 173.150(e) or (f)
of this subchapter or has a flash point
above 60
°
C (140
°
F) but below 93
°
C (200
°
F).
(e)
Column 4: Identification number.
Column 4 lists the identification num-
ber assigned to each proper shipping
name. Those preceded by the letters
‘‘UN’’ are associated with proper ship-
ping names considered appropriate for
international transportation as well as
domestic transportation. Those pre-
ceded by the letters ‘‘NA’’ are associ-
ated with proper shipping names not
recognized for transportation outside
of the United States. Identification
numbers in the ‘‘NA9000’’ series are as-
sociated with proper shipping names
not appropriately covered by inter-
national hazardous materials (dan-
gerous goods) transportation stand-
ards, or not appropriately addressed by
international transportation standards
for emergency response information
purposes, except for transportation in
the United States. Those preceded by
the letters ‘‘ID’’ are associated with
proper shipping names recognized by
the ICAO Technical Instructions (see
§ 171.7 of this subchapter for avail-
ability).
(f)
Column 5: Packing group.
Column 5
specifies one or more packing groups
assigned to a material corresponding to
the proper shipping name and hazard
class for that material. Class 2, Class 7,
and Division 6.2 do not have packing
groups. Articles in classes other than
Class 1 are not assigned to packing
groups. For packing purposes, any re-
quirement for a specific packaging per-
formance level is set out in the appli-
cable packing authorizations of part
173. Packing Groups I, II, and III indi-
cate the degree of danger presented by
the material is great, medium, or
minor, respectively. If more than one
packing group is indicated for an
entry, the packing group for the haz-
ardous material is determined using
the criteria for assignment of packing
groups specified in subpart D of part
173. When a reevaluation of test data or
new data indicates a need to modify
the specified packing group(s), the data
should be submitted to the Associate
Administrator. Each reference in this
column to a material that is a haz-
ardous waste or a hazardous substance,
and whose proper shipping name pre-
ceded in Column 1 of the Table by the
letter ‘‘A’’ or ‘‘W,’’ is modified to read
‘‘III’’ on those occasions when the ma-
terial is offered for transportation or
transported by a mode in which its
transportation is not otherwise subject
to requirements of this subchapter.
(g)
Column 6: Labels.
Column 6 speci-
fies codes which represent the hazard
warning labels required for a package
filled with a material conforming to
the associated hazard class and proper
shipping name, unless the package is
otherwise excepted from labeling by a
provision in subpart E of this part, or
part 173 of this subchapter. The first
code is indicative of the primary haz-
ard of the material. Additional label
codes are indicative of subsidiary haz-
ards. Provisions in § 172.402 may require
that a label other than that specified
in Column 6 be affixed to the package
in addition to that specified in Column
6. No label is required for a material
classed as a combustible liquid or for a
Class 3 material that is reclassed as a
combustible liquid. For ‘‘Empty’’ label
requirements, see § 173.428 of this sub-
chapter. The codes contained in Col-
umn 6 are defined according to the fol-
lowing table:

(h)
Column 7: Special provisions.
Col-
umn 7 specifies codes for special provi-
sions applicable to hazardous mate-
rials. When Column 7 refers to a special
provision for a hazardous material, the
meaning and requirements of that spe-
cial provision are as set forth in
§ 172.102 of this subpart.
(i)
Column 8: Packaging authorizations.
Columns 8A, 8B and 8C specify the ap-
plicable sections for exceptions, non-
bulk packaging requirements and bulk
packaging requirements, respectively,
in part 173 of this subchapter. Columns
8A, 8B and 8C are completed in a man-
ner which indicates that ‘‘§ 173.’’ pre-
cedes the designated numerical entry.
For example, the entry ‘‘202’’ in Col-
umn 8B associated with the proper
shipping name ‘‘Gasoline’’ indicates
that for this material conformance to
non-bulk packaging requirements pre-
scribed in § 173.202 of this subchapter is
required. When packaging require-
ments are specified, they are in addi-
tion to the standard requirements for
all packagings prescribed in § 173.24 of
this subchapter and any other applica-
ble requirements in subparts A and B
of part 173 of this subchapter.
(1) Exceptions. Column 8A contains
exceptions from some of the require-
ments of this subchapter. The ref-
erenced exceptions are in addition to
those specified in subpart A of part 173
and elsewhere in this subchapter. A
‘‘None’’ in this column means no pack-
aging exceptions are authorized, except
as may be provided by special provi-
sions in Column 7.
(2) Non-bulk packaging. Column 8B
references the section in part 173 of
this subchapter which prescribes pack-
aging requirements for non-bulk pack-
agings. A ‘‘None’’ in this column means
non-bulk packagings are not author-
ized, except as may be provided by spe-
cial provisions in Column 7. Each ref-
erence in this column to a material
which is a hazardous waste or a haz-
ardous substance, and whose proper
shipping name is preceded in Column 1
of the Table by the letter ‘‘A’’ or ‘‘W’’,
is modified to include ‘‘§ 173.203’’ or
‘‘§ 173.213’’, as appropriate for liquids
and solids, respectively, on those occa-
sions when the material is offered for
transportation or transported by a
mode in which its transportation is not
otherwise subject to the requirements
of this subchapter.
(3)
Bulk packaging.
Column (8C) speci-
fies the section in part 173 of this sub-
chapter that prescribes packaging re-
quirements for bulk packagings, sub-
ject to the limitations, requirements,
and additional authorizations of Col-
umns (7) and (8B). A ‘‘None’’ in Column
(8C) means bulk packagings are not au-
thorized, except as may be provided by
special provisions in Column (7) and in
packaging authorizations Column (8B).
Additional authorizations and limita-
tions for use of UN portable tanks are
set forth in Column 7. For each ref-
erence in this column to a material
that is a hazardous waste or a haz-
ardous substance, and whose proper
shipping name is preceded in Column 1
of the Table by the letter ‘‘A’’ or ‘‘W’’
and that is offered for transportation
or transported by a mode in which its
transportation is not otherwise subject
to the requirements of this subchapter:
(i) The column reference is § 173.240 or
§ 173.241, as appropriate.
(ii) For a solid material, the excep-
tion provided in special provision B54 is
applicable.
(iii) For a Class 9 material, which
meets the definition of an elevated
temperature material, the column ref-
erence is § 173.247.
(4) For a hazardous material which is
specifically named in the Table and
whose packaging sections specify pack-
agings not applicable to the form of the
material (e.g., packaging specified is
for solid material and the material is
159
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.101
being offered for transportation in a
liquid form) the following table should
be used to determine the appropriate
packaging section:

Cylinders.
For cylinders, both non-
bulk and bulk packaging authoriza-
tions are set forth in Column (8B). Not-
withstanding a designation of ‘‘None’’
in Column (8C), a bulk cylinder may be
used when specified through the sec-
tion reference in Column (8B).
(j)
Column 9: Quantity limitations.
Col-
umns 9A and 9B specify the maximum
quantities that may be offered for
transportation in one package by pas-
senger-carrying aircraft or passenger-
carrying rail car (Column 9A) or by
cargo aircraft only (Column 9B), sub-
ject to the following:
(1) ‘‘Forbidden’’ means the material
may not be offered for transportation
or transported in the applicable mode
of transport.
(2) The quantity limitation is ‘‘net’’
except where otherwise specified, such
as for ‘‘Consumer commodity’’ which
specifies ‘‘30 kg gross.’’
(3) When articles or devices are spe-
cifically listed by name, the net quan-
tity limitation applies to the entire ar-
ticle or device (less packaging and
packaging materials) rather than only
to its hazardous components.
(4) A package offered or intended for
transportation by aircraft and which is
filled with a material forbidden on pas-
senger-carrying aircraft but permitted
on cargo aircraft only, or which ex-
ceeds the maximum net quantity au-
thorized on passenger-carrying air-
craft, shall be labelled with the CARGO
AIRCRAFT ONLY label specified in
§ 172.448 of this part.
(5) The total net quantity of haz-
ardous material for an outer non-bulk
packaging that contains more than one
hazardous material may not exceed the
lowest permitted maximum net quan-
tity per package as shown in Column
9A or 9B, as appropriate. If one mate-
rial is a liquid and one is a solid, the
maximum net quantity must be cal-
culated in kilograms.
See
§ 173.24a(c)(1)(iv).
(k)
Column 10: Vessel stowage require-
ments.
Column 10A [Vessel stowage]
specifies the authorized stowage loca-
tions on board cargo and passenger ves-
sels. Column 10B [Other provisions]
specifies codes for stowage and han-
dling requirements for specific haz-
ardous materials. Hazardous materials
offered for transportation as limited
quantities are allocated stowage cat-
egory A and are not subject to the
stowage codes assigned by column 10B.
The meaning of each code in Column
10B is set forth in § 176.84 of this sub-
chapter. Section 176.63 of this sub-
chapter sets forth the physical require-
ments for each of the authorized loca-
tions listed in Column 10A. (For bulk
transportation by vessel, see 46 CFR
parts 30 to 40, 70, 98, 148, 151, 153 and
154.) The authorized stowage locations
specified in Column 10A are defined as
follows:
(1) Stowage category ‘‘A’’ means the
material may be stowed ‘‘on deck’’ or
‘‘under deck’’ on a cargo vessel or on a
passenger vessel.
(2) Stowage category ‘‘B’’ means—
(i) The material may be stowed ‘‘on
deck’’ or ‘‘under deck’’ on a cargo ves-
sel and on a passenger vessel carrying
a number of passengers limited to not
more than the larger of 25 passengers,
or one passenger per each 3 m of over-
all vessel length; and
(ii) ‘‘On deck only’’ on passenger ves-
sels in which the number of passengers
specified in paragraph (k)(2)(i) of this
section is exceeded.
(3) Stowage category ‘‘C’’ means the
material must be stowed ‘‘on deck
only’’ on a cargo vessel or on a pas-
senger vessel.
(4) Stowage category ‘‘D’’ means the
material must be stowed ‘‘on deck
only’’ on a cargo vessel or on a pas-
senger vessel carrying a number of pas-
sengers limited to not more than the
larger of 25 passengers or one passenger
per each 3 m of overall vessel length,
but the material is prohibited on a pas-
senger vessel in which the limiting
number of passengers is exceeded.
(5) Stowage category ‘‘E’’ means the
material may be stowed ‘‘on deck’’ or
160
49 CFR Ch. I (10–1–23 Edition)
§ 172.101
‘‘under deck’’ on a cargo vessel or on a
passenger vessel carrying a number of
passengers limited to not more than
the larger of 25 passengers, or one pas-
senger per each 3 m of overall vessel
length, but is prohibited from carriage
on a passenger vessel in which the lim-
iting number of passengers is exceeded.
(6) Stowage category ‘‘01’’ means the
material may be stowed ‘‘on deck’’ in
closed cargo transport units or ‘‘under
deck’’ on a cargo vessel (up to 12 pas-
sengers) or on a passenger vessel.
(7) Stowage category ‘‘02’’ means the
material may be stowed ‘‘on deck’’ in
closed cargo transport units or ‘‘under
deck’’ on a cargo vessel (up to 12 pas-
sengers) or ‘‘on deck’’ in closed cargo
transport units or ‘‘under deck’’ in
closed cargo transport units on a pas-
senger vessel.
(8) Stowage category ‘‘03’’ means the
material may be stowed ‘‘on deck’’ in
closed cargo transport units or ‘‘under
deck’’ on a cargo vessel (up to 12 pas-
sengers) but the material is prohibited
on a passenger vessel.
(9) Stowage category ‘‘04’’ means the
material may be stowed ‘‘on deck’’ in
closed cargo transport units or ‘‘under
deck’’ in closed cargo transports on a
cargo vessel (up to 12 passengers) but
the material is prohibited on a pas-
senger vessel.
(10) Stowage category ‘‘05’’ means the
material may be stowed ‘‘on deck’’ in
closed cargo transport units on a cargo
vessel (up to 12 passengers) but the ma-
terial is prohibited on a passenger ves-
sel.
(l)

UANTITIES
1. This appendix lists materials and their
corresponding reportable quantities (RQ’s)
that are listed or designated as ‘‘hazardous
substances’’ under section 101(14) of the Com-
prehensive Environmental Response, Com-
pensation, and Liability Act, 42 U.S.C.
9601(14) (CERCLA; 42 U.S.C. 9601
et seq
). This
listing fulfills the requirement of CERCLA,
42 U.S.C. 9656(a), that all ‘‘hazardous sub-
stances,’’ as defined in 42 U.S.C. 9601(14), be
listed and regulated as hazardous materials
under 49 U.S.C. 5101–5127. That definition in-
cludes substances listed under sections
311(b)(2)(A) and 307(a) of the Federal Water
Pollution Control Act, 33 U.S.C. 1321(b)(2)(A)
and 1317(a), section 3001 of the Solid Waste
Disposal Act, 42 U.S.C. 6921, and section 112
of the Clean Air Act, 42 U.S.C. 7412. In addi-
tion, this list contains materials that the
Administrator of the Environmental Protec-
tion Agency has determined to be hazardous
substances in accordance with section 102 of
CERCLA, 42 U.S.C. 9602. It should be noted
that 42 U.S.C. 9656(b) provides that common
and contract carriers may be held liable
under laws other than CERCLA for the re-
lease of a hazardous substance as defined in
that Act, during transportation that com-
menced before the effective date of the list-
ing and regulating of that substance as a
hazardous material under 49 U.S.C. 5101–5127.
2. This appendix is divided into two TA-
BLES which are entitled ‘‘TABLE 1—HAZ-
ARDOUS SUBSTANCES OTHER THAN
RADIONUCLIDES’’ and ‘‘TABLE 2—RADIO-
NUCLIDES.’’ A material listed in this appen-
dix is regulated as a hazardous material and
a hazardous substance under this subchapter
if it meets the definition of a hazardous sub-
stance in § 171.8 of this subchapter.
3. The procedure for selecting a proper
shipping name for a hazardous substance is
set forth in § 172.101(c).
4. Column 1 of TABLE 1, entitled
‘‘Haz-
ardous substance’’,
contains the names of
those elements and compounds that are haz-
ardous substances. Following the listing of
elements and compounds is a listing of waste
streams. These waste streams appear on the
list in numerical sequence and are referenced
by the appropriate ‘‘D’’, ‘‘F’’, or ‘‘K’’ num-
bers. Column 2 of TABLE 1, entitled
‘‘Re-
portable quantity (RQ)’’,
contains the report-
able quantity (RQ), in pounds and kilograms,
for each hazardous substance listed in Col-
umn 1 of TABLE 1.
5. A series of notes is used throughout
TABLE 1 and TABLE 2 to provide additional
information concerning certain hazardous
substances. These notes are explained at the
end of each TABLE.
6. TABLE 2 lists radionuclides that are
hazardous substances and their cor-
responding RQ’s. The RQ’s in table 2 for
radionuclides are expressed in units of curies
and terabecquerels, whereas those in table 1
are expressed in units of pounds and kilo-
grams. If a material is listed in both table 1
and table 2, the lower RQ shall apply. Radio-
nuclides are listed in alphabetical order. The
RQ’s for radionuclides are given in the radio-
logical unit of measure of curie, abbreviated
‘‘Ci’’, followed, in parentheses, by an equiva-
lent unit measured in terabecquerels, abbre-
viated ‘‘TBq’’.
7. For mixtures of radionuclides, the fol-
lowing requirements shall be used in deter-
mining if a package contains an RQ of a haz-
ardous substance: (i) if the identity and
quantity (in curies or terabecquerels) of each
radionuclide in a mixture or solution is
known, the ratio between the quantity per
package (in curies or terabecquerels) and the
RQ for the radionuclide must be determined
for each radionuclide. A package contains an
RQ of a hazardous substance when the sum of
the ratios for the radionuclides in the mix-
ture or solution is equal to or greater than
one; (ii) if the identity of each radionuclide
in a mixture or solution is known but the
quantity per package (in curies or
terabecquerels) of one or more of the radio-
nuclides is unknown, an RQ of a hazardous
substance is present in a package when the
total quantity (in curies or terabecquerels)
of the mixture or solution is equal to or
greater than the lowest RQ of any individual
radionuclide in the mixture or solution; and
(iii) if the identity of one or more radio-
nuclides in a mixture or solution is unknown
(or if the identity of a radionuclide by itself
is unknown), an RQ of a hazardous substance
is present when the total quantity (in curies
or terabecquerels) in a package is equal to or
greater than either one curie or the lowest
RQ of any known individual radionuclide in
the mixture or solution, whichever is lower.

$ The RQs for all radionuclides apply to chemical com-
pounds containing the radionuclides and elemental forms re-
gardless of the diameter of pieces of solid material.
† The RQ of one curie applies to all radionuclides not oth-
erwise listed. Whenever the RQs in TABLE 1—HAZARDOUS
SUBSTANCES OTHER THAN RADIONUCLIDES and this
table conflict, the lowest RQ shall apply. For example, uranyl
acetate and uranyl nitrate have RQs shown in TABLE 1 of
100 pounds, equivalent to about one-tenth the RQ level for
uranium-238 in this table.
** The method to determine the RQs for mixtures or solu-
tions of radionuclides can be found in paragraph 7 of the note
preceding TABLE 1 of this appendix. RQs for the following
four common radionuclide mixtures are provided: radium-226
in secular equilibrium with its daughters (0.053 curie); natural
uranium (0.1 curie); natural uranium in secular equilibrium
with its daughters (0.052 curie); and natural thorium in secular
equilibrium with its daughters (0.011 curie).
*** Indicates that the name was added by PHMSA because
it appears in the list of radionuclides in 49 CFR 173.435. The
reportable quantity (RQ), if not specifically listed elsewhere in
this appendix, shall be determined in accordance with the pro-
cedures in paragraph 7 of this appendix.

1. See § 171.4 of this subchapter for applica-
bility to marine pollutants. This appendix
lists potential marine pollutants as defined
in § 171.8 of this subchapter.
2. Marine pollutants listed in this appendix
are not necessarily listed by name in the
§ 172.101 Table. If a marine pollutant not list-
ed by name or by synonym in the § 172.101
Table meets the definition of any hazard
Class 1 through 8, then you must determine
the class and division of the material in ac-
cordance with § 173.2a of this subchapter. You
must also select the most appropriate haz-
ardous material description and proper ship-
ping name. If a marine pollutant not listed
by name or by synonym in the § 172.101 Table
does not meet the definition of any Class 1
through 8, then you must offer it for trans-
portation under the most appropriate of the
following two Class 9 entries: ‘‘Environ-
mentally hazardous substances, liquid,
n.o.s.,’’ UN3082, or ‘‘Environmentally haz-
ardous substances, solid, n.o.s.’’ UN3077.
3. This appendix contains two columns.
The first column, entitled ‘‘S.M.P.’’ (for se-
vere marine pollutants), identifies whether a
material is a severe marine pollutant. If the
letters ‘‘PP’’ appear in this column for a ma-
terial, the material is a severe marine pol-
lutant, otherwise it is not. The second col-
umn, entitled ‘‘Marine Pollutant’’ , lists the
marine pollutants.
4. If a material is not listed in this appen-
dix and meets the criteria for a marine pol-
lutant as provided in Chapter 2.9 of the
IMDG Code, (incorporated by reference; see
§ 171.7 of this subchapter), the material may
be transported as a marine pollutant in ac-
cordance with the applicable requirements of
this subchapter.
5. If a material or a solution meeting the
definition of a marine pollutant in § 171.8 of
this subchapter does not meet the criteria
for a marine pollutant as provided in section
2.9.3.3 and 2.9.3.4 of the IMDG Code, (incor-
porated by reference; see § 171.7 of this sub-
chapter), it may be excepted from the re-
quirements of this subchapter as a marine
pollutant if that exception is approved by
the Associate Administrator.

§ 172.102
Special provisions.
(a)
General.
When column 7 of the
§ 172.101 table refers to a special provi-
sion for a hazardous material, the
meaning and requirements of that pro-
vision are as set forth in this section.
When a special provision specifies
packaging or packaging require-
ments—
(1) The special provision is in addi-
tion to the standard requirements for
all packagings prescribed in § 173.24 of
this subchapter and any other applica-
ble packaging requirements in subparts
A and B of part 173 of this subchapter;
and
(2) To the extent a special provision
imposes limitations or additional re-
quirements on the packaging provi-
sions set forth in column 8 of the
§ 172.101 table, packagings must con-
form to the requirements of the special
provision.
(b)
Description of codes for special pro-
visions.
Special provisions contain
packaging provisions, prohibitions, ex-
ceptions from requirements for par-
ticular quantities or forms of materials
and requirements or prohibitions appli-
cable to specific modes of transpor-
tation, as follows:
(1) A code consisting only of numbers
(for example, ‘‘11’’) is multi-modal in
application and may apply to bulk and
non-bulk packagings.
(2) A code containing the letter ‘‘A’’
refers to a special provision which ap-
plies only to transportation by air-
craft.
(3) A code containing the letter ‘‘B’’
refers to a special provision that ap-
plies only to bulk packaging require-
ments. Unless otherwise provided in
this subchapter, these special provi-
sions do not apply to UN, IM Specifica-
tion portable tanks or IBCs.
(4) A code containing the letters ‘‘IB’’
or ‘‘IP’’ refers to a special provision
that applies only to transportation in
IBCs.
(5) A code containing the letter ‘‘N’’
refers to a special provision which ap-
plies only to non-bulk packaging re-
quirements.
(6) A code containing the letter ‘‘R’’
refers to a special provision which ap-
plies only to transportation by rail.
(7) A code containing the letter ‘‘T’’
refers to a special provision which ap-
plies only to transportation in UN or
IM Specification portable tanks.
(8) A code containing the letters
‘‘TP’’ refers to a portable tank special
provision for UN or IM Specification
portable tanks that is in addition to
those provided by the portable tank in-
structions or the requirements in part
178 of this subchapter.
(9) A code containing the letter ‘‘W’’
refers to a special provision that ap-
plies only to transportation by water.
(c)
Tables of special provisions.
The fol-
lowing tables list, and set forth the re-
quirements of, the special provisions
referred to in column 7 of the § 172.101
table.

These provi-
sions are multi-modal and apply to
bulk and non-bulk packagings:
Code/Special Provisions
1
This material is poisonous by inhalation
(see § 171.8 of this subchapter) in Hazard
Zone A (see § 173.116(a) or § 173.133(a) of this
subchapter), and must be described as an
inhalation hazard under the provisions of
this subchapter.
2
This material is poisonous by inhalation
(see § 171.8 of this subchapter) in Hazard
Zone B (see § 173.116(a) or § 173.133(a) of this
subchapter), and must be described as an
inhalation hazard under the provisions of
this subchapter.
3
This material is poisonous by inhalation
(see § 171.8 of this subchapter) in Hazard
Zone C (see § 173.116(a) of this subchapter),
and must be described as an inhalation
hazard under the provisions of this sub-
chapter.
4
This material is poisonous by inhalation
(see § 171.8 of this subchapter) in Hazard
Zone D (see § 173.116(a) of this subchapter),
and must be described as an inhalation
hazard under the provisions of this sub-
chapter.
5
If this material meets the definition for a
material poisonous by inhalation (see
§ 171.8 of this subchapter), a shipping name
must be selected which identifies the inha-
lation hazard, in Division 2.3 or Division
6.1, as appropriate.
6
This material is poisonous-by-inhalation
and must be described as an inhalation
hazard under the provisions of this sub-
chapter.
8
A hazardous substance that is not a haz-
ardous waste may be shipped under the
shipping description ‘‘Other regulated sub-
stances, liquid
or
solid, n.o.s.’’, as appro-
priate. In addition, for solid materials, spe-
cial provision B54 applies.
354
49 CFR Ch. I (10–1–23 Edition)
§ 172.102
9
Packaging for certain PCBs for disposal
and storage is prescribed by EPA in 40 CFR
761.60 and 761.65.
11
The hazardous material must be pack-
aged as either a liquid or a solid, as appro-
priate, depending on its physical form at 55
°
C (131
°
F) at atmospheric pressure.
12
In concentrations greater than 40 per-
cent, this material has strong oxidizing
properties and is capable of starting fires
in contact with combustible materials. If
appropriate, a package containing this ma-
terial must conform to the additional la-
beling requirements of § 172.402 of this sub-
chapter.
13
The words ‘‘Inhalation Hazard’’ shall be
entered on each shipping paper in associa-
tion with the shipping description, shall be
marked on each non-bulk package in asso-
ciation with the proper shipping name and
identification number, and shall be marked
on two opposing sides of each bulk pack-
age. Size of marking on bulk package must
conform to § 172.302(b) of this subchapter.
The requirements of §§ 172.203(m) and
172.505 of this subchapter do not apply.
14
Motor fuel antiknock mixtures are:
a. Mixtures of one or more organic lead
mixtures (such as tetraethyl lead,
triethylmethyl lead, diethyldimethyl
lead, ethyltrimethyl lead, and
tetramethyl lead) with one or more halo-
gen compounds (such as ethylene
dibromide and ethylene dichloride), hy-
drocarbon solvents or other equally effi-
cient stabilizers; or
b. tetraethyl lead.
15

dichloroisocyanuric acid does not meet the
criteria for inclusion in Division 5.1 (Oxi-
dizer) and is not subject to the require-
ments of this subchapter unless meeting
the criteria for inclusion in another class
or division.
30
Sulfur is not subject to the requirements
of this subchapter if transported in a non-
bulk packaging or if formed to a specific
shape (for example, prills, granules, pel-
lets, pastilles, or flakes). A bulk packaging
containing sulfur is not subject to the
placarding requirements of subpart F of
this part, if it is marked with the appro-
priate identification number as required by
subpart D of this part. Molten sulfur must
be marked as required by § 172.325 of this
subchapter.
31
Materials which have undergone suffi-
cient heat treatment to render them non-
hazardous are not subject to the require-
ments of this subchapter.
32
Polymeric beads and molding compounds
may be made from polystyrene,
poly(methyl methacrylate) or other poly-
meric material.
33
Ammonium nitrites and mixtures of an
inorganic nitrite with an ammonium salt
are prohibited.
34

§ 172.102
37
Unless it can be demonstrated by testing
that the sensitivity of the substance in its
frozen state is no greater than in its liquid
state, the substance must remain liquid
during normal transport conditions. It
must not freeze at temperatures above
¥
15
°
C (5
°
F).
38
If this material shows a violent effect in
laboratory tests involving heating under
confinement, the labeling requirements of
Special Provision 53 apply, and the mate-
rial must be packaged in accordance with
packing method OP6 in § 173.225 of this sub-
chapter. If the SADT of the technically
pure substance is higher than 75
°
C, the
technically pure substance and formula-
tions derived from it are not self-reactive
materials and, if not meeting any other
hazard class, are not subject to the re-
quirements of this subchapter.
39
This substance may be carried under pro-
visions other than those of Class 1 only if
it is so packed that the percentage of
water will not fall below that stated at any
time during transport. When phlegmatized
with water and inorganic inert material,
the content of urea nitrate must not ex-
ceed 75 percent by mass and the mixture
should not be capable of being detonated
by test 1(a)(i) or test 1(a)(ii) in the UN
Manual of Tests and Criteria (IBR, see
§ 171.7 of this subchapter).
40
Polyester resin kits consist of two com-
ponents: A base material (either Class 3 or
Division 4.1, Packing Group II or III) and
an activator (organic peroxide), each sepa-
rately packed in an inner packaging. The
organic peroxide must be type D, E, or F,
not requiring temperature control. The
components may be placed in the same
outer packaging provided they will not
interact dangerously in the event of leak-
age. The Packing Group assigned will be II
or III, according to the classification cri-
teria for either Class 3 or Division 4.1, as
appropriate, applied to the base material.
Additionally, unless otherwise excepted in
this subchapter, polyester resin kits must
be packaged in specification combination
packagings based on the performance level
of the base material contained within the
kit.
41
This material at the Packing Group II
hazard criteria level may be transported in
Large Packagings.
43
The membrane filters, including paper
separators and coating or backing mate-
rials, that are present in transport, must
not be able to propagate a detonation as
tested by one of the tests described in the
UN Manual of Tests and Criteria, Part I,
Test series 1(a) (IBR, see § 171.7 of this sub-
chapter). On the basis of the results of
suitable burning rate tests, and taking
into account the standard tests in the UN
Manual of Tests and Criteria, Part III, sub-
section 33.2.1 (IBR, see § 171.7 of this sub-
chapter), nitrocellulose membrane filters
in the form in which they are to be trans-
ported that do not meet the criteria for a
Division 4.1 material are not subject to the
requirements of this subchapter. Pack-
agings must be so constructed that explo-
sion is not possible by reason of increased
internal pressure. Nitrocellulose mem-
brane filters covered by this entry, each
with a mass not exceeding 0.5 g, are not
subject to the requirements of this sub-
chapter when contained individually in an
article or a sealed packet.
44
The formulation must be prepared so
that it remains homogenous and does not
separate during transport. Formulations
with low nitrocellulose contents and nei-
ther showing dangerous properties when
tested for their ability to detonate,
deflagrate or explode when heated under
defined confinement by the appropriate
test methods and criteria in the UN Man-
ual of Tests and Criteria (IBR, see § 171.7 of
this subchapter), nor classed as a Division
4.1 (flammable solid) when tested in ac-
cordance with the procedures specified in
§ 173.124 of this subchapter (chips, if nec-
essary, crushed and sieved to a particle
size of less than 1.25 mm), are not subject
to the requirements of this subchapter.
45
Temperature should be maintained be-
tween 18
°
C (64.4
°
F) and 40
°
C (104
°
F).
Tanks containing solidified methacrylic
acid must not be reheated during trans-
port.
46
This material must be packed in accord-
ance with packing method OP6 (see § 173.225
of this subchapter). During transport, it
must be protected from direct sunshine
and stored (or kept) in a cool and well-ven-
tilated place, away from all sources of
heat.
47

this subchapter and flammable liquids may
be transported under this entry without
first applying the classification criteria of
Division 4.1, provided there is no free liquid
visible at the time the material is loaded
or at the time the packaging or transport
unit is closed. Except when the liquids are
fully absorbed in solid material contained
in sealed bags, for single packagings, each
packaging must correspond to a design
type that has passed a leakproofness test
at the Packing Group II level. Sealed pack-
ets and articles containing less than 10 mL
of a Class 3 liquid in Packing Group II or
III absorbed onto a solid material are not
subject to this subchapter provided there is
no free liquid in the packet or article.
48
Mixtures of solids that are not subject to
this subchapter and toxic liquids may be
transported under this entry without first

§ 172.102
this subchapter. Alternatively, the item
itself may be used as a packaging if it
meets the general packaging requirements
of subparts A and B of part 173 of this sub-
chapter.
101
The name of the particular substance or
article must be specified.
102
The ends of the detonating cord must be
tied fast so that the explosive cannot es-
cape. The articles may be transported as in
Division 1.4 Compatibility Group D (1.4D) if
all of the conditions specified in § 173.63(a)
of this subchapter are met.
105
The word ‘‘Agents’’ may be used instead
of ‘‘Explosives’’ when approved by the As-
sociate Administrator.
106
The recognized name of the particular
explosive may be specified in addition to
the type.
107
The classification of the substance is ex-
pected to vary especially with the particle
size and packaging but the border lines
have not been experimentally determined;
appropriate classifications should be
verified following the test procedures in
§§ 173.57 and 173.58 of this subchapter.
108
Fireworks must be so constructed and
packaged that loose pyrotechnic composi-
tion will not be present in packages during
transportation.
109
Rocket motors must be nonpropulsive
in transportation unless approved in ac-
cordance with § 173.56 of this subchapter. A
rocket motor to be considered ‘‘nonpropul-
sive’’ must be capable of unrestrained
burning and must not appreciably move in
any direction when ignited by any means.
110
Fire extinguishers transported under
UN1044 and oxygen cylinders transported
for emergency use under UN1072 may in-
clude installed actuating cartridges (car-
tridges, power device of Division 1.4C or
1.4S), without changing the classification
of Division 2.2, provided the aggregate
quantity of deflagrating (propellant) explo-
sives does not exceed 3.2 grams per cyl-
inder. Oxygen cylinders with installed ac-
tuating cartridges as prepared for trans-
portation must have an effective means of
preventing inadvertent activation.
111
Explosive substances of Division 1.1
Compatibility Group A (1.1A) are forbidden
for transportation if dry or not desen-
sitized, unless incorporated in a device.
113
The sample must be given a tentative
approval by an agency or laboratory in ac-
cordance with § 173.56 of this subchapter.
114
Jet perforating guns, charged, oil well,
without detonator may be reclassed to Di-
vision 1.4 Compatibility Group D (1.4D) if
the following conditions are met:
a. The total weight of the explosive con-
tents of the shaped charges assembled in
the guns does not exceed 90.5 kg (200
pounds) per vehicle; and
b. The guns are packaged in accordance
with Packing Method US 1 as specified in
§ 173.62 of this subchapter.
115
Boosters with detonator, detonator as-
semblies and boosters with detonators in
which the total explosive charge per unit
does not exceed 25 g, and which will not
mass detonate and undergo only limited
propagation in the shipping package may
be assigned to 1.4B classification code.
Mass detonate means more than 90 percent
of the devices tested in a package explode
practically simultaneously. Limited propa-
gation means that if one booster near the
center of the package is exploded, the ag-
gregate weight of explosives, excluding ig-
nition and delay charges, in this and all
additional boosters in the outside pack-
aging that explode may not exceed 25 g.
116
Fuzes, detonating may be classed in Di-
vision 1.4 if the fuzes do not contain more
than 25 g of explosive per fuze and are
made and packaged so that they will not
cause functioning of other fuzes, explosives
or other explosive devices if one of the
fuzes detonates in a shipping packaging or
in adjacent packages.
117
If shipment of the explosive substance is
to take place at a time that freezing
weather is anticipated, the water con-
tained in the explosive substance must be
mixed with denatured alcohol so that
freezing will not occur.
118
This substance may not be transported
under the provisions of Division 4.1 unless
specifically authorized by the Associate
Administrator (see UN0143 or UN0150 as ap-
propriate).
119
This substance, when in quantities of
not more than 11.5 kg (25.3 pounds), with
not less than 10 percent water, by mass,
also may be classed as Division 4.1, pro-
vided a negative test result is obtained
when tested in accordance with test series
6(c) of the UN Manual of Tests and Criteria
(IBR, see § 171.7 of this subchapter).
120
The phlegmatized substance must be
significantly less sensitive than dry PETN.
121
This substance, when containing less al-
cohol, water or phlegmatizer than speci-
fied, may not be transported unless ap-
proved by the Associate Administrator.
123
Any explosives, blasting, type C con-
taining chlorates must be segregated from
explosives containing ammonium nitrate
or other ammonium salts.
125
Lactose or glucose or similar materials
may be used as a phlegmatizer provided
that the substance contains not less than
90%, by mass, of phlegmatizer. These mix-
tures may be classified in Division 4.1 when
tested in accordance with test series 6(c) of
the UN Manual of Tests and Criteria (IBR,
see § 171.7 of this subchapter) and approved
by the Associate Administrator. Testing
must be conducted on at least three pack-
ages as prepared for transport. Mixtures
358

§ 172.102
containing at least 98%, by mass, of
phlegmatizer are not subject to the re-
quirements of this subchapter. Packages
containing mixtures with not less than 90%
by mass, of phlegmatizer need not bear a
POISON subsidiary risk label.
127
Mixtures containing oxidizing and or-
ganic materials transported under this
entry may not meet the definition and cri-
teria of a Class 1 material. (See § 173.50 of
this subchapter.)
128
Regardless of the provisions of
§ 172.101(c)(12), aluminum smelting by-prod-
ucts and aluminum remelting by-products
described under this entry, meeting the
definition of Class 8, Packing Group II and
III may be classed as a Division 4.3 mate-
rial and transported under this entry. The
presence of a Class 8 hazard must be com-
municated as required by this part for sub-
sidiary hazards.
129
These materials may not be classified
and transported unless authorized by the
Associate Administrator on the basis of re-
sults from Series 2 Test and a Series 6(c)
Test from the UN Manual of Tests and Cri-
teria (IBR, see § 171.7 of this subchapter) on
packages as prepared for transport. The
packing group assignment and packaging
must be approved by the Associate Admin-
istrator for Hazardous Materials Safety on
the basis of the criteria in § 173.21 of this
subchapter and the package type used for
the Series 6(c) test.
130
‘‘Batteries, dry, sealed, n.o.s.,’’ com-
monly referred to as dry batteries, are her-
metically sealed and generally utilize met-
als (other than lead) and/or carbon as elec-
trodes. These batteries are typically used
for portable power applications. The re-
chargeable (and some non-rechargeable)
types have gelled alkaline electrolytes
(rather than acidic) making it difficult for
them to generate hydrogen or oxygen when
overcharged and therefore, differentiating
them from non-spillable batteries. Dry bat-
teries specifically covered by another
entry in the § 172.101 Table must be trans-
ported in accordance with the require-
ments applicable to that entry. For exam-
ple, nickel-metal hydride batteries trans-
ported by vessel in certain quantities are
covered by another entry (
see
Batteries,
nickel-metal hydride, UN3496). Dry bat-
teries not specifically covered by another
entry in the § 172.101 Table are covered by
this entry (
i.e.,
Batteries, dry, sealed,
n.o.s.) and are not subject to requirements
of this subchapter except for the following:
(a)
Incident reporting.
For transportation
by aircraft, a telephone report in accord-
ance with § 171.15(a) is required if a fire,
violent rupture, explosion or dangerous
evolution of heat (
i.e.,
an amount of heat
sufficient to be dangerous to packaging
or personal safety to include charring of
packaging, melting of packaging, scorch-
ing of packaging, or other evidence) oc-
curs as a direct result of a dry battery.
For all modes of transportation, a writ-
ten report submitted, retained, and up-
dated in accordance with § 171.16 is re-
quired if a fire, violent rupture, explosion
or dangerous evolution of heat occurs as
a direct result of a dry battery or bat-
tery-powered device.
(b)
Preparation for transport.
Batteries and
battery-powered device(s) containing
batteries must be prepared and packaged
for transport in a manner to prevent:
(1) A dangerous evolution of heat;
(2) Short circuits, including but not lim-
ited to the following methods:
(i) Packaging each battery or each battery-
powered device when practicable, in fully
enclosed inner packagings made of non-
conductive material;
(ii) Separating or packaging batteries in a
manner to prevent contact with other
batteries, devices or conductive mate-
rials (
e.g.,
metal) in the packagings; or
(iii) Ensuring exposed terminals or connec-
tors are protected with non-conductive
caps, non-conductive tape, or by other
appropriate means; and
(3) Damage to terminals. If not impact re-
sistant, the outer packaging should not
be used as the sole means of protecting
the battery terminals from damage or
short circuiting. Batteries must be se-
curely cushioned and packed to prevent
shifting which could loosen terminal
caps or reorient the terminals to produce
short circuits. Batteries contained in de-
vices must be securely installed. Ter-
minal protection methods include but
are not limited to the following:
(i) Securely attaching covers of sufficient
strength to protect the terminals;
(ii) Packaging the battery in a rigid plastic
packaging; or
(iii) Constructing the battery with termi-
nals that are recessed or otherwise pro-
tected so that the terminals will not be
subjected to damage if the package is
dropped.
(c)
Additional air transport requirements.
For
a battery whose voltage (electrical po-
tential) exceeds 9 volts—
(1) When contained in a device, the device
must be packaged in a manner that pre-
vents unintentional activation or must
have an independent means of preventing
unintentional activation (
e.g.,
packaging
restricts access to activation switch,
switch caps or locks, recessed switches,
trigger locks, temperature sensitive cir-
cuit breakers,
etc.
); and
(2) An indication of compliance with this
special provision must be provided by
marking each package with the words
‘‘not restricted’’ or by including the
words ‘‘not restricted’’ on a transport
359
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.102
document such as an air waybill accom-
panying the shipment.
(d)
Used or spent battery exception.
Used or
spent dry batteries of both non-recharge-
able and rechargeable designs, with a
marked rating up to 9-volt that are com-
bined in the same package and trans-
ported by highway or rail for recycling,
reconditioning, or disposal are not sub-
ject to this special provision or any other
requirement of the HMR. Note that bat-
teries utilizing different chemistries (
i.e.,
those battery chemistries specifically
covered by another entry in the § 172.101
Table) as well as dry batteries with a
marked rating greater than 9-volt may
not be combined with used or spent bat-
teries in the same package. Note also
that this exception does not apply to bat-
teries that have been reconditioned for
reuse.
131
This material may not be offered for
transportation unless approved by the As-
sociate Administrator.
132
This description may only be used for
ammonium nitrate-based compound fer-
tilizers. They must be classified in accord-
ance with the procedure as set out in the
Manual of Tests and Criteria, part III, sec-
tion 39 (IBR,
see
§ 171.7 of this subchapter).

identification number are only subject to
the requirements of this subchapter when
offered for transportation and transported
by air or vessel.
134
This entry applies only to vehicles pow-
ered by wet batteries, sodium batteries,
lithium metal batteries or lithium ion bat-
teries, and equipment powered by wet bat-
teries or sodium batteries that are trans-
ported with these batteries installed. Lith-
ium batteries installed in a cargo trans-
port unit, designed only to provide power
external to the transport unit must use the
proper shipping name ‘‘Lithium batteries
installed in cargo transport unit’’ found in
the § 172.101 Hazardous Materials Table.
a. For the purpose of this special provision,
vehicles are self-propelled apparatus de-
signed to carry one or more persons or
goods. Examples of such vehicles are
electrically-powered cars, motorcycles,
scooters, three- and four-wheeled vehi-
cles or motorcycles, trucks, locomotives,
bicycles (pedal cycles with an electric
motor) and other vehicles of this type
(
e.g.,
self-balancing vehicles or vehicles
not equipped with at least one seating
position), lawn tractors, self-propelled
farming and construction equipment,
boats, aircraft, wheelchairs and other
mobility aids. This includes vehicles
transported in a packaging. In this case,
some parts of the vehicle may be de-
tached from its frame to fit into the
packaging.
b. Examples of equipment are lawnmowers,
cleaning machines, or model boats and
model aircraft. Equipment powered by
lithium metal batteries or lithium ion
batteries must be described using the en-
tries ‘‘Lithium metal batteries contained

teries packed with equipment’’ or ‘‘Lith-
ium ion batteries contained in equip-
ment’’ or ‘‘Lithium ion batteries packed
with equipment,’’ as appropriate.
c. Self-propelled vehicles or equipment
that also contain an internal combustion
engine must be described using the en-
tries ‘‘Engine, internal combustion,
flammable gas powered’’ or ‘‘Engine, in-
ternal combustion, flammable liquid
powered’’ or ‘‘Vehicle, flammable gas
powered’’ or ‘‘Vehicle, flammable liquid
powered,’’ as appropriate. These entries
include hybrid electric vehicles powered
by both an internal combustion engine
and batteries. Additionally, self-pro-
pelled vehicles or equipment that con-
tain a fuel cell engine must be described
using the entries ‘‘Engine, fuel cell, flam-
mable gas powered’’ or ‘‘Engine, fuel cell,
flammable liquid powered’’ or ‘‘Vehicle,
fuel cell, flammable gas powered’’ or
‘‘Vehicle, fuel cell, flammable liquid
powered,’’ as appropriate. These entries
include hybrid electric vehicles powered
by a fuel cell engine, an internal combus-
tion engine, and batteries.
135
Internal combustion engines installed in
a vehicle must be described using ‘‘Vehicle,
flammable gas powered’’ or ‘‘Vehicle, flam-
mable liquid powered,’’ as appropriate. If a
vehicle is powered by a flammable liquid
and a flammable gas internal combustion
engine, it must be described using ‘‘Vehi-
cle, flammable gas powered.’’ This includes
hybrid electric vehicles powered by both an
internal combustion engine and wet, so-
dium or lithium batteries installed. If a
fuel cell engine is installed in a vehicle,
the vehicle must be described using ‘‘Vehi-
cle, fuel cell, flammable gas powered’’ or
‘‘Vehicle, fuel cell, flammable liquid pow-
ered,’’ as appropriate. This includes hybrid
electric vehicles powered by a fuel cell, an
internal combustion engine, and wet, so-
dium or lithium batteries installed. For
the purpose of this special provision, vehi-
cles are self-propelled apparatus designed
to carry one or more persons or goods. Ex-
amples of such vehicles are cars, motor-
cycles, trucks, locomotives, scooters,
three- and four-wheeled vehicles or motor-
cycles, lawn tractors, self-propelled farm-
ing and construction equipment, boats, and
aircraft. Furthermore, lithium batteries
installed in a cargo transport unit, de-

§ 172.201
Preparation and retention of
shipping papers.
(a)
Contents.
When a description of
hazardous material is required to be in-
cluded on a shipping paper, that de-
scription must conform to the fol-
lowing requirements:
(1) When a hazardous material and a
material not subject to the require-
ments of this subchapter are described
on the same shipping paper, the haz-
ardous material description entries re-
quired by § 172.202 and those additional
entries that may be required by
§ 172.203:
(i) Must be entered first, or
(ii) Must be entered in a color that
clearly contrasts with any description
on the shipping paper of a material not
subject to the requirements of this sub-
chapter, except that a description on a
reproduction of a shipping paper may
be highlighted, rather than printed, in
a contrasting color (the provisions of
this paragraph apply only to the basic
description required by § 172.202(a)(1),
(2), (3), and (4)), or
(iii) Must be identified by the entry
of an ‘‘X’’ placed before the basic ship-
ping description required by § 172.202 in
a column captioned ‘‘HM.’’ (The ‘‘X’’
may be replaced by ‘‘RQ,’’ if appro-
priate.)
(2) The required shipping description
on a shipping paper and all copies of
the shipping paper used for transpor-
tation purposes must be legible and
printed (manually or mechanically) in
English.
(3) Unless it is specifically authorized
or required in this subchapter, the re-
quired shipping description may not
contain any code or abbreviation.
(4) A shipping paper may contain ad-
ditional information concerning the
material provided the information is
not inconsistent with the required de-
scription. Unless otherwise permitted
or required by this subpart, additional
information must be placed after the
basic description required by
§ 172.202(a).
(5)
Electronic shipping papers.
For
transportation by rail, a rail carrier
may accept shipping paper information
either telephonically (i.e., voice com-
munications and facsimiles) or elec-
tronically (EDI) from an offeror of a
hazardous materials shipment in ac-
cordance with the provisions in para-
graphs (a)(5)(i)–(a)(5)(iv) of this section.
See § 171.8 for the EDI definition.
(i) When the information applicable
to the consignment is provided under
this requirement the information must
be available to the offeror and carrier
at all times during transport, and the
carrier must have and maintain a
printed copy of this information until
delivery of the hazardous materials on
the shipping paper is complete. When a
386
49 CFR Ch. I (10–1–23 Edition)
§ 172.202
paper document is produced, the data
must be presented as required by this
subpart.
(ii) The offeror must forward the
shipping paper (record) for a loaded
movement to the carrier prior to ship-
ment unless the carrier prepares the
shipping paper on behalf of the offeror.
The offeror is only relieved of the duty
to forward the shipping paper once the
offeror has received a copy of the ship-
ping paper from the carrier;
(iii) A carrier that generates a res-
idue shipping paper using information
from the previous loaded movement of
a hazardous materials packaging must
ensure the description of the hazardous
material that accompanies the ship-
ment complies with the offeror’s re-
quest; and
(iv)
Verification.
The carrier and the
offeror must have a procedure by which
the offeror can verify accuracy of the
transmitted hazard communication in-
formation that will accompany the
shipment.
(b) [Reserved]
(c)
Continuation page.
A shipping
paper may consist of more than one
page, if each page is consecutively
numbered and the first page bears a no-
tation specifying the total number of
pages included in the shipping paper.
For example, ‘‘Page 1 of 4 pages.’’
(d)
Emergency response telephone num-
ber.
Except as provided in § 172.604(d), a
shipping paper must contain an emer-
gency response telephone number and,
if utilizing an emergency response in-
formation telephone number service
provider, identify the person (by name
or contract number) who has a contrac-
tual agreement with the service pro-
vider, as prescribed in subpart G of this
part.
(e)
Retention and Recordkeeping.
Each
person who provides a shipping paper
must retain a copy of the shipping
paper required by § 172.200(a), or an
electronic image thereof, that is acces-
sible at or through its principal place
of business and must make the ship-
ping paper available, upon request, to
an authorized official of a Federal,
State, or local government agency at
reasonable times and locations. For a
hazardous waste, the shipping paper
copy must be retained for three years
after the material is accepted by the
initial carrier. For all other hazardous
materials, the shipping paper must be
retained for two years after the mate-
rial is accepted by the initial carrier.
Each shipping paper copy must include
the date of acceptance by the initial
carrier, except that, for rail, vessel, or
air shipments, the date on the ship-
ment waybill, airbill, or bill of lading
may be used in place of the date of ac-
ceptance by the initial carrier. A
motor carrier (as defined in § 390.5 of
subchapter B of chapter III of subtitle
B) using a shipping paper without
change for multiple shipments of one
or more hazardous materials having
the same shipping name and identifica-
tion number may retain a single copy
of the shipping paper, instead of a copy
for each shipment made, if the carrier
also retains a record of each shipment
made, to include shipping name, identi-
fication number, quantity transported,
and date of shipment.

gross mass per package must be shown.
Where different hazardous materials in
limited quantities are packed together
in the same outer packaging, when a
gross mass is indicated Column 4 of
§ 173.27 Table 3, the net quantity of
each hazardous material must be
shown in addition to the gross mass of
the completed package.
(viii) For authorized consumer com-
modities, the information provided
may be either the gross mass of each
package or the average gross mass of
the packages.
(7) The number and type of packages
must be indicated. The type of pack-
ages must be indicated by description
of the package (for example, ‘‘12
drums’’). Indication of the packaging
specification number (‘‘1H1’’) may be
388
49 CFR Ch. I (10–1–23 Edition)
§ 172.203
included in the description of the pack-
age (for example, ‘‘12 1H1 drums’’ or ‘‘12
drums (UN 1A1)’’). Abbreviations may
be used for indicating packaging types
(for example, ‘‘cyl.’’ for ‘‘cylinder’’)

are deemed to comply with this para-
graph.
(c)(1) The total quantity of the mate-
rial covered by one description must
appear before or after, or both before
and after, the description required and
authorized by this subpart. The type of
packaging and destination marks may
be entered in any appropriate manner
before or after the basic description.
Abbreviations may be used to express
units of measurement and types of
packagings.
(2) Hazardous materials and haz-
ardous substances transported by high-
way considered ‘‘household wastes’’ as
defined in 40 CFR 261.4, and not subject
to the Environmental Protection Agen-
cy’s hazardous waste regulations in 40
CFR parts 262 and 263, are excepted
from the requirements of this para-
graph.
(d) Technical and chemical group
names may be entered in parentheses
between the proper shipping name and

pected to contain an unknown Cat-
egory A infectious substance must
have the words ‘‘suspected Category A
infectious substance’’ entered in paren-
theses in place of the technical name
as part of the proper shipping descrip-
tion. For additional technical name op-
tions, see the definition for ‘‘Technical
name’’ in § 171.8. A technical name
should not be marked on the outer
package of a Division 6.2 material (see
§ 172.301(b)).
(1) If a hazardous material is a mix-
ture or solution of two or more haz-
ardous materials, the technical names
of at least two components most pre-
dominately contributing to the hazards
of the mixture or solution must be en-
tered on the shipping paper as required
by paragraph (k) of this section. For
example, ‘‘UN 2924, Flammable liquid,
corrosive, n.o.s., 3 (8), II (contains
Methanol, Potassium hydroxide)’’.
(2) The provisions of this paragraph
do not apply—
(i) To a material that is a hazardous
waste and described using the proper
shipping name ‘‘Hazardous waste, liq-
uid
or
solid, n.o.s.’’, classed as a mis-
cellaneous Class 9, provided the EPA
hazardous waste number is included on
the shipping paper in association with
the basic description, or provided the
material is described in accordance
with the provisions of § 172.203(c) of this
part.
(ii) To a material for which the haz-
ard class is to be determined by testing
under the criteria in § 172.101(c)(11).
(iii) If the n.o.s. description for the
material (other than a mixture of haz-
ardous materials of different classes
meeting the definitions of more than
one hazard class) contains the name of
the chemical element or group which is
primarily responsible for the material
being included in the hazard class indi-
cated.
(iv) If the n.o.s. description for the
material (which is a mixture of haz-
ardous materials of different classes
meeting the definition of more than
one hazard class) contains the name of
the chemical element or group respon-
sible for the material meeting the defi-
nition of one of these classes. In such
cases, only the technical name of the
component that is not appropriately
identified in the n.o.s. description shall
be entered in parentheses.
(l)
Marine pollutants.
(1) For a proper
shipping name used to describe a haz-
ardous material that is a marine pol-
lutant, either assigned the letter ‘‘G’’
in column (1) of the § 172.101 hazardous
materials table, or that contains the
text ‘‘n.o.s.’’, the name of the compo-
nent that makes the material a marine
pollutant must appear in parentheses
in association with the basic descrip-
tion. Where two or more components
that make the material a marine pol-
lutant are present, the names of at
least two of the components most pre-
dominantly contributing to the marine
pollutant designation must appear in
parentheses in association with the
basic description. For material de-
scribed using ‘‘UN3077, Environ-
mentally hazardous substance, solid,
n.o.s.’’ and ‘‘UN3082, Environmentally
hazardous substance, liquid, n.o.s.,’’
see
§ 172.102(c)(1), special provision 441 for
additional provisions.
(2) The words ‘‘Marine Pollutant’’
shall be entered in association with the
basic description for a material which
is a marine pollutant.
(3) Except for transportation by ves-
sel, marine pollutants subject to the
392
49 CFR Ch. I (10–1–23 Edition)
§ 172.204
provisions of 49 CFR 130.11 are excepted
from the requirements of paragraph (l)
of this section if a phrase indicating
the material is an oil is placed in asso-
ciation with the basic description.
(4) Except when all or part of trans-
portation is by vessel, marine pollut-
ants in non-bulk packagings are not
subject to the requirements of para-
graphs (l)(1) and (l)(2) of this section
(see § 171.4 of this subchapter).
(m)
Poisonous Materials.
Notwith-
standing the hazard class to which a
material is assigned, for materials that
are poisonous by inhalation (see § 171.8
of this subchapter), the words ‘‘Poison-
Inhalation Hazard’’ or ‘‘Toxic-Inhala-
tion Hazard’’ and the words ‘‘Zone A’’,
‘‘Zone B’’, ‘‘Zone C’’, or ‘‘Zone D’’ for
gases or ‘‘Zone A’’ or ‘‘Zone B’’ for liq-
uids, as appropriate, shall be entered
on the shipping paper immediately fol-
lowing the shipping description. The
word ‘‘Poison’’ or ‘‘Toxic’’ need not be
repeated if it otherwise appears in the
shipping description.
(n)
Elevated temperature materials.
If a
liquid material in a package meets the
definition of an elevated temperature
material in § 171.8 of this subchapter,
and the fact that it is an elevated tem-
perature material is not disclosed in
the proper shipping name (for example,
when the words ‘‘Molten’’ or ‘‘Elevated
temperature’’ are part of the proper
shipping name), the word ‘‘HOT’’ must
immediately precede the proper ship-
ping name of the material on the ship-
ping paper.
(o)
Organic peroxides, polymerizing sub-
stances, and self-reactive materials.
The
description on a shipping paper for a
Division 4.1 (polymerizing substance
and self-reactive) material or a Divi-
sion 5.2 (organic peroxide) material
must include the following additional
information, as appropriate:
(1) If notification or competent au-
thority approval is required, the ship-
ping paper must contain a statement of
approval of the classification and con-
ditions of transport.
(2) For Division 4.1 (polymerizing
substance and self-reactive) and Divi-
sion 5.2 (organic peroxide) materials
that require temperature control dur-
ing transport, the words ‘‘TEMPERA-
TURE CONTROLLED’’ must be added
as part of the proper shipping name,
unless already part of the proper ship-
ping name. The control and emergency
temperature must be included on the
shipping paper.
(3) The word ‘‘SAMPLE’’ must be in-
cluded in association with the basic de-
scription when a sample of a Division
4.1 (self-reactive) material (see
§ 173.224(c)(3) of this subchapter) or Di-
vision 5.2 (organic peroxide) material
(see § 173.225(b)(2) of this subchapter) is
offered for transportation.
(p)
Liquefied petroleum gas (LPG).
The
word ‘‘non-odorized’’ or ‘‘not-odorized’’
must be included in association with
the proper shipping description on a
shipping paper when non-odorized liq-
uefied petroleum gas is offered for
transportation.
(q)
Holding time.
The date at which
the actual holding time ends, as cal-
culated in accordance with § 178.338–9,
must be provided on the shipping paper
in association with the basic descrip-
tion for refrigerated liquefied gases
transported in a portable tank.

fest (excluding the EPA identification
numbers, generator certification and
signatures) and, for exports, an EPA
Acknowledgment of Consent accom-
panies the hazardous waste at all
times. Intermediate rail transporters
are not required to sign either the
manifest or shipping paper.
(3) When delivering hazardous waste
to the designated facility, a rail trans-
porter must:
(i) Obtain the date of delivery and
handwritten signature of the owner or
operator of the designated facility on
the manifest or the shipping paper (if
the manifest has not been received by
the facility); and
(ii) Retain a copy of the manifest or
signed shipping paper in accordance
with 40 CFR 263.22.
(4) When delivering hazardous waste
to a non-rail transporter, a rail trans-
porter must:
(i) Obtain the date of delivery and
the handwritten signature of the next
non-rail transporter on the manifest;
and
(ii) Retain a copy of the manifest in

subpart, may be used as the shipping
paper required by this subpart.
(i) The shipping description for a haz-
ardous waste must be modified as re-
quired by § 172.101(c)(9).
(j) Electronic manifests that are ob-
tained, completed, and transmitted in
accordance with 40 CFR262.20(a)(3), and
used in accordance with 40 CFR 262.24
in lieu of EPA Forms 8700–22 and 8700–
22A are the legal equivalent of paper
manifest forms bearing handwritten
signatures, and satisfy for all purposes
any requirements in these regulations
to obtain, complete, sign, provide, use,
or retain a manifest. Electronic signa-
tures in conformance with 40 CFR
262.25 are therefore acceptable in lieu
of handwritten signatures required by
paragraphs (c) and (d) of this section
provided one printed copy of the elec-
tronic manifest bearing the electronic
signature is provided to the initial
transporter as required by 40 CFR
262.24(d). A copy of the electronic mani-
fest would satisfy the 3-year retention
requirement for maintaining a copy of
the manifest.

Identification numbers.
Except as
otherwise provided in this subpart, no
person may offer for transportation or
transport a hazardous material in a
bulk packaging unless the packaging is
marked as required by § 172.332 with the
identification number specified for the
material in the § 172.101 table—
(1) On each side and each end, if the
packaging has a capacity of 3,785 L
(1,000 gallons) or more;
(2) On two opposing sides, if the pack-
aging has a capacity of less than 3,785
L (1,000 gallons); or
(3) For cylinders permanently in-
stalled on a tube trailer motor vehicle,
on each side and each end of the motor
vehicle.
(b)
Size of markings.
Except as other-
wise provided, markings required by
this subpart on bulk packagings
must—
(1) Have a width of at least 6.0 mm
(0.24 inch) and a height of at least 100
mm (3.9 inches) for rail cars;
(2) Have a width of at least 4.0 mm
(0.16 inch) and a height of at least 12
mm (0.47 inch) for portable tanks with
capacities of less than 3,785 L (1,000 gal-
lons) and a width of at least 4.0 mm
(0.16 inch) and a height of 25 mm (one
inch) for IBCs; and

Except
as provided in § 173.23 of this sub-
chapter, the outside of each package
used under the terms of a special per-
mit must be plainly and durably
marked ‘‘DOT–SP’’ followed by the spe-
cial permit number assigned. Packages
authorized by an exemption issued
prior to October 1, 2007 may be plainly
and durably marked ‘‘DOT–E’’ in lieu
of ‘‘DOT–SP’’ followed by the number
assigned as specified in the most recent
version of that exemption.
(d) Each bulk packaging marked with
a proper shipping name, common name
or identification number as required by
this subpart must remain marked when
it is emptied unless it is—
(1) Sufficiently cleaned of residue and
purged of vapors to remove any poten-
tial hazard; or
(2) Refilled, with a material requiring
different markings or no markings, to
such an extent that any residue re-
maining in the packaging is no longer
hazardous.
(e) Additional requirements for
marking portable tanks, cargo tanks,
tank cars, multi-unit tank car tanks,
and other bulk packagings are pre-
scribed in §§ 172.326, 172.328, 172.330, and

§ 172.403
Class 7 (radioactive) mate-
rial.
(a) Unless excepted from labeling by
§§ 173.421 through 173.427 of this sub-
chapter, each package of radioactive
material must be labeled as provided in
this section.
(b) The proper label to affix to a
package of Class 7 (radioactive) mate-
rial is based on the radiation level at
the surface of the package and the
transport index. The proper category of
label must be determined in accord-
ance with paragraph (c) of this section.
The label to be applied must be the
highest category required for any of
the two determining conditions for the
package. RADIOACTIVE WHITE-I is
the lowest category and RADIO-
ACTIVE YELLOW-III is the highest.
For example, a package with a trans-
port index of 0.8 and a maximum sur-
face radiation level of 0.6 millisievert
(60 millirems) per hour must bear a
RADIOACTIVE YELLOW-III label.

See § 173.428(e) of
this subchapter for EMPTY labeling re-
quirements.
(e)
FISSILE label.
For packages re-
quired in § 172.402 to bear a FISSILE
label, each such label must be com-
pleted with the criticality safety index
(CSI) assigned in the NRC or DOE
package design approval, or in the cer-
tificate of approval for special arrange-
ment or the certificate of approval for
the package design issued by the Com-
petent Authority for import and export
shipments. For overpacks and freight
containers required in § 172.402 to bear
a FISSILE label, the CSI on the label
must be the sum of the CSIs for all of
the packages contained in the over-
pack or freight container.
(f) Each package required by this sec-
tion to be labeled with a RADIO-
ACTIVE label must have two of these
labels, affixed to opposite sides of the
package. (See § 172.406(e)(3) for freight
container label requirements).
(g) The following applicable items of
information must be entered in the
blank spaces on the RADIOACTIVE
label by legible printing (manual or
mechanical), using a durable weather
resistant means of marking:
(1)
Contents.
Except for LSA-1 mate-
rial, the names of the radionuclides as
taken from the listing of radionuclides
in § 173.435 of this subchapter (symbols
which conform to established radiation
protection terminology are authorized,
i.e.
,
99
Mo,
60
Co, etc.). For mixtures of
radionuclides, with consideration of
space available on the label, the radio-
nuclides that must be shown must be
determined in accordance with
§ 173.433(g) of this subchapter. For LSA-
I material, the term ‘‘LSA-I’’ may be
used in place of the names of the radio-
nuclides.
(2)
Activity.
The maximum activity of
the radioactive contents in the pack-
age during transport must be expressed
in appropriate SI units (
e.g.,
Becquerels
(Bq), Terabecquerels (TBq)). The activ-
ity may also be stated in appropriate
customary units (
e.g.,
Curies (Ci),
milliCuries (mCi), microCuries (uCi))
in parentheses following the SI units.
Abbreviations are authorized. Except
for plutonium-239 and plutonium-241,
the weight in grams or kilograms of
fissile radionuclides (or the mass of
each fissile nuclide for mixtures when
appropriate) may be inserted instead of
activity units. For plutonium-239 and
plutonium-241, the weight in grams of
fissile radionuclides (or the mass of
each fissile nuclide for mixtures when
appropriate) may be inserted in addi-
tion to the activity units.
(3)
Transport index.
(see § 173.403 of
this subchapter.)
(h) When one or more packages of
Class 7 (radioactive) material are
placed within an overpack, the over-
pack must be labeled as prescribed in
this section, except as follows:
(1) The ‘‘contents’’ entry on the label
may state ‘‘mixed’’ in place of the
names of the radionuclides unless each
inside package contains the same
radionuclide(s).
(2) The ‘‘activity’’ entry on the label
must be determined by adding together
the number of becquerels of the Class 7
(radioactive) materials packages con-
tained therein.
(3) For an overpack, the transport
index (TI) must be determined by add-
ing together the transport indices of
the Class 7 (radioactive) materials
packages contained therein, except
that for a rigid overpack, the transport
index (TI) may alternatively be deter-
mined by direct measurement as pre-
scribed in § 173.403 of this subchapter
under the definition for ‘‘transport
index,’’ taken by the person initially
offering the packages contained within
the overpack for shipment.
(4) The category of Class 7 label for
the overpack must be determined from
the table in § 172.403(c) using the TI de-
rived according to paragraph (h)(3) of
this section, and the maximum radi-
ation level on the surface of the over-
pack.
(5) The category of the Class 7 label
of the overpack, and not that of any of
the packages contained therein, must
be used in accordance with Table 1 of
§ 172.504(e) to determine when the
transport vehicle must be placarded.
(6) For fissile material, the criti-
cality safety index which must be en-
tered on the overpack FISSILE label is
the sum of the criticality safety indi-
ces of the individual packages in the
overpack, as stated in the certificate of
approval for the package design issued

§ 172.404
Labels for mixed and consoli-
dated packaging.
(a)
Mixed packaging.
When compatible
hazardous materials having different
hazard classes are packed within the
same packaging, or within the same
outside container or overpack as de-
scribed in § 173.25, the packaging, out-
side container or overpack must be la-
beled as required for each class of haz-
ardous material contained therein.
(b)
Consolidated packaging.
When two
or more packages containing compat-
ible hazardous materials are placed
within the same outside container or
overpack, the outside container or
overpack must be labeled as required
for each class of hazardous material
contained therein, unless labels rep-
resentative of each hazardous material
in the outside container or overpack
are visible.
(c)
Consolidation bins used by a single
motor carrier.
Notwithstanding the pro-
visions of paragraph (b) of this section,
labeling of a consolidation bin is not
required under the following condi-
tions:
(1) The consolidation bin must be re-
usable, made of materials such as plas-
tic, wood, or metal and must have a ca-
pacity of 64 cubic feet or less;
(2) Hazardous material packages
placed in the consolidation bin must be
properly labeled in accordance with
this subpart;
(3) Packages must be compatible as
specified in § 177.848 of this subchapter;
(4) Packages may only be placed
within the consolidation bin and the
bin be loaded on a motor vehicle by an
employee of a single motor carrier;
(5) Packages must be secured within
the consolidation bin by other pack-
ages or by other suitable means in such
a manner as to prevent shifting of, or
significant relative motion between,
the packages that would likely com-
promise the integrity of any package;
(6) The consolidation bin must be
clearly and legibly marked on a tag or
fixed display device with an indication
of each hazard class or division con-
tained within the bin;
(7) The consolidation bin must be
properly blocked and braced within the
transport vehicle; and
(8) Consolidation bins may only be
transported by a single motor carrier,
or on railcars transporting such vehi-
cles.

§ 172.405
Authorized label modifica-
tions.
(a) For Classes 1, 2, 3, 4, 5, 6, and 8,
text indicating a hazard (for example
FLAMMABLE LIQUID) is not required
on a primary or subsidiary label.
(b) For a package containing Oxygen,
compressed, or Oxygen, refrigerated
liquid, the OXIDIZER label specified in
§ 172.426 of this subpart, modified to dis-
play the word ‘‘OXYGEN’’ instead of
‘‘OXIDIZER’’, and the class number
‘‘2’’ instead of ‘‘5.1’’, may be used in
place of the NON-FLAMMABLE GAS
and OXIDIZER labels. Notwithstanding
the provisions of paragraph (a) of this
section, the word ‘‘OXYGEN’’ must ap-
pear on the label.
(c) For a package containing a Divi-
sion 6.1, Packing Group III material,
the POISON label specified in § 172.430
may be modified to display the text
‘‘PG III’’ instead of ‘‘POISON’’ or
‘‘TOXIC’’ below the mid line of the
label. Also see § 172.313(d).

§ 172.406
Placement of labels.
(a)
General.
(1) Except as provided in
paragraphs (b) and (e) of this section,
each label required by this subpart
must—
(i) Be printed on or affixed to a sur-
face (other than the bottom) of the
package or containment device con-
taining the hazardous material;
(ii) Be located on the same surface of
the package and near the proper ship-
ping name marking, if the package di-
mensions are adequate; and
(iii) For transportation by aircraft,
the entire label(s) must appear on one
423
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.407
side of the package. For cylindrical
packages, the label must be of such di-
mensions that it will not overlap itself.
In the case of cylindrical packages con-
taining radioactive materials, which
require two identical labels, these la-
bels must be centered on opposite
points of the circumference and must
not overlap each other. If the dimen-
sions of the package are such that two
identical labels cannot be affixed with-
out overlapping each other, one label is
acceptable provided it does not overlap
itself.
(2) Except as provided in paragraph
(e) of this section, duplicate labeling is
not required on a package or contain-
ment device (such as to satisfy redun-
dant labeling requirements).
(b)
Exceptions.
A label may be printed
on or placed on a securely affixed tag,
or may be affixed by other suitable
means to:
(1) A package that contains no radio-
active material and which has dimen-
sions less than those of the required
label;
(2) A cylinder; and
(3) A package which has such an ir-
regular surface that a label cannot be
satisfactorily affixed.
(c)
Placement of multiple labels.
When
primary and subsidiary hazard labels
are required, they must be displayed
next to each other. Placement con-
forms to this requirement if labels are
within 150 mm (6 inches) of one an-
other.
(d)
Contrast with background.
Each
label must be printed on or affixed to a
background color contrasting to the
color specification of the label as re-
quired by § 172.407(d)(1), or must have a
dotted or solid line outer border, to en-
hance the visibility of the label. How-
ever, the dotted or solid line outer bor-
der may also be used for backgrounds
of contrasting color.
(e)
Duplicate labeling.
Generally, only
one of each different required label
must be displayed on a package. How-
ever, duplicate labels must be dis-
played on at least two sides or two
ends (other than the bottom) of—
(1) Each package or overpack having
a volume of 1.8 m
3
(64 cubic feet) or
more;
(2) Each non-bulk package containing
a radioactive material;
(3) Each DOT 106 or 110 multi-unit
tank car tank. Labels must be dis-
played on each end;
(4) Each portable tank of less than
3,785 L (1000 gallons) capacity;
(5) Each freight container or aircraft
unit load device having a volume of 1.8
m
3
(64 cubic feet) or more, but less than
18 m
3
(640 cubic feet). One of each re-
quired label must be displayed on or
near the closure; and
(6) An IBC having a volume of 1.8 m
3
(64 cubic feet) or more.
(f)
Visibility.
A label must be clearly
visible and may not be obscured by
markings or attachments.

General specifications for
placards.
(a)
Strength and durability.
Placards
must conform to the following:
(1) A placard may be made of any
plastic, metal or other material capa-
ble of withstanding, without deteriora-
tion or a substantial reduction in effec-
tiveness, a 30-day exposure to open
weather conditions.
(2) A placard made of tagboard must
be at least equal to that designated
442
49 CFR Ch. I (10–1–23 Edition)
§ 172.519
commercially as white tagboard. Tag-
board must have a weight of at least 80
kg (176 pounds) per ream of 610 by 910
mm (24 by 36-inch) sheets, water-
proofing materials included. In addi-
tion, each placard made of tagboard
must be able to pass a 414 kPa (60 p.s.i.)
Mullen test.
(3) Reflective or retroreflective mate-
rials may be used on a placard if the
prescribed colors, strength and dura-
bility are maintained.
(b)
Design.
(1) Except as provided in
§ 172.332 of this part, each placard must
be as described in this subpart, and ex-
cept for size and color, the printing,
inner border and symbol must be as
shown in §§ 172.521 through 172.560 of
this subpart, as appropriate.
(2) The dotted line border shown on
each placard is not part of the placard
specification. However, a dotted or
solid line outer border may be used
when needed to indicate the full size of
a placard that is part of a larger for-
mat or is on a background of a non-
contrasting color.
(3) For other than Class 7 or the
DANGEROUS placard, text indicating
a hazard (for example, ‘‘FLAM-
MABLE’’) is not required. Text may be
omitted from the OXYGEN placard
only if the specific identification num-
ber is displayed on the placard.
(4) For a placard corresponding to the
primary or subsidiary hazard class of a
material, the hazard class or division
number must be displayed in the lower
corner of the placard. However, a per-
manently affixed subsidiary placard
meeting the specifications of this sec-
tion which were in effect on October 1,
2001, (such as, a placard without the
hazard class or division number dis-
played in the lower corner of the
placard) and which was installed prior
to September 30, 2001, may continue to
be used as a subsidiary placard in do-
mestic transportation by rail or high-
way, provided the color tolerances are
maintained and are in accordance with
the display requirements in this sub-
chapter.
(c)
Size.
(1) Each diamond (square-on-
point) placard prescribed in this sub-
part must measure at least 250 mm
(9.84 inches) on each side and must
have a solid line inner border approxi-
mately 12.5 mm inside and parallel to
the edge. The 12.5 mm measurement is
from the outside edge of the placard to
the outside of the solid line forming
the inner border. For domestic trans-
portation, a placard manufactured
prior to January 1, 2017, in conform-
ance with the requirements of this
paragraph in effect on December 31,
2014, may continue in service until the
end of its useful life provided the color
tolerances are maintained and are in
accordance with the display require-
ments of this subchapter.
(2) Except as otherwise provided in
this subpart, the hazard class or divi-
sion number, as appropriate, must be
shown in numerals measuring at least
41 mm (1.6 inches) in height.
(3) Except as otherwise provided in
this subpart, when text indicating a
hazard is displayed on a placard, the
printing must be in letters measuring
at least 41 mm (1.6 inches) in height.
(d)
Color.
(1) The background color,
symbol, text, numerals and inner bor-
der on a placard must be as specified in
§§ 172.521 through 172.560 of this sub-
part, as appropriate.
(2) Black and any color on a placard
must be able to withstand, without
substantial change—
(i) A 72-hour fadeometer test (for a
description of equipment designed for
this purpose, see ASTM G 23–69 or
ASTM G 26–70); and
(ii) A 30-day exposure to open weath-
er.
(3) Upon visual examination, a color
on a placard must fall within the color
tolerances displayed on the appropriate
Hazardous Materials Label and Placard
Color Tolerance Chart (see
§ 172.407(d)(4)). As an alternative, the
PANTONE
formula guide coated/
uncoated as specified for colors in
§ 172.407(d)(5) may be used.
(4) The placard color must extend to
the inner border and may extend to the
edge of the placard in the area des-
ignated on each placard except the
color on the CORROSIVE and RADIO-
ACTIVE placards (black and yellow, re-
spectively) must extend only to the
inner border.
(e)
Form identification.
A placard may
contain form identification informa-
tion, including the name of its maker,
provided that information is printed
443
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.523
outside of the solid line inner border in
no larger than 10-point type.
(f)
Exceptions.
When hazardous mate-
rials are offered for transportation or
transported under the provisions of
subpart C of part 171 of this subchapter,
a placard conforming to the specifica-
tions in the UN Recommendations, the
ICAO Technical Instructions, the
IMDG Code, or the Transport Canada
TDG Regulations (IBR, see § 171.7 of
this subchapter) may be used in place
of a corresponding placard conforming
to the requirements of this subpart.
However, a bulk packaging, transport
vehicle, or freight container containing
a material poisonous by inhalation (see
§ 171.8 of this subchapter) must be plac-
arded in accordance with this subpart
(see § 171.23(b)(10) of this subchapter).
(g)
Trefoil symbol.
The trefoil symbol
on the RADIOACTIVE placard must
meet the appropriate specification in
appendix B of this part.

§ 172.602
Emergency response infor-
mation.
(a)
Information required.
For purposes
of this subpart, the term ‘‘emergency
response information’’ means informa-
tion that can be used in the mitigation
of an incident involving hazardous ma-
terials and, as a minimum, must con-
tain the following information:
(1) The basic description and tech-
nical name of the hazardous material
as required by §§ 172.202 and 172.203(k),
the ICAO Technical Instructions, the
IMDG Code, or the TDG Regulations,
as appropriate (IBR, see § 171.7 of this
subchapter);
(2) Immediate hazards to health;
(3) Risks of fire or explosion;
(4) Immediate precautions to be
taken in the event of an accident or in-
cident;
(5) Immediate methods for handling
fires;
(6) Initial methods for handling spills
or leaks in the absence of fire; and
(7) Preliminary first aid measures.
(b)
Form of information.
The informa-
tion required for a hazardous material
by paragraph (a) of this section must
be:
(1) Printed legibly in English;
(2) Available for use away from the
package containing the hazardous ma-
terial; and
(3) Presented—
(i) On a shipping paper;
(ii) In a document, other than a ship-
ping paper, that includes both the basic
description and technical name of the
hazardous material as required by
§§ 172.202 and 172.203(k), the ICAO Tech-
nical Instructions, the IMDG Code, or
the TDG Regulations, as appropriate,
and the emergency response informa-
tion required by this subpart (e.g., a
material safety data sheet); or
(iii) Related to the information on a
shipping paper, a written notification
to pilot-in-command, or a dangerous
cargo manifest, in a separate document
(e.g., an emergency response guidance
454
49 CFR Ch. I (10–1–23 Edition)
§ 172.604
document), in a manner that cross-ref-
erences the description of the haz-
ardous material on the shipping paper
with the emergency response informa-
tion contained in the document.
Aboard aircraft, the ICAO ‘‘Emergency
Response Guidance for Aircraft Inci-
dents Involving Dangerous Goods’’ and,
aboard vessels, the IMO ‘‘Emergency
Procedures for Ships Carrying Dan-
gerous Goods’’, or equivalent docu-
ments, may be used to satisfy the re-
quirements of this section for a sepa-
rate document.
(c)
Maintenance of information.
Emer-
gency response information shall be
maintained as follows:
(1)
Carriers.
Each carrier who trans-
ports a hazardous material shall main-
tain the information specified in para-
graph (a) of this section and § 172.606 of
this part in the same manner as pre-
scribed for shipping papers, except that
the information must be maintained in
the same manner aboard aircraft as the
notification of pilot-in-command, and
aboard vessels in the same manner as
the dangerous cargo manifest. This in-
formation must be immediately acces-
sible to train crew personnel, drivers of
motor vehicles, flight crew members,
and bridge personnel on vessels for use
in the event of incidents involving haz-
ardous materials.
(2)
Facility operators.
Each operator of
a facility where a hazardous material
is received, stored or handled during
transportation, shall maintain the in-
formation required by paragraph (a) of
this section whenever the hazardous
material is present. This information
must be in a location that is imme-
diately accessible to facility personnel
in the event of an incident involving
the hazardous material.

§ 172.604
Emergency response tele-
phone number.
(a) A person who offers a hazardous
material for transportation must pro-
vide a numeric emergency response
telephone number, including the area
code, for use in an emergency involving
the hazardous material. For telephone
numbers outside the United States, the
international access code or the ‘‘+’’
(plus) sign, country code, and city
code, as appropriate, that are needed to
complete the call must be included.
The telephone number must be—
(1) Monitored at all times the haz-
ardous material is in transportation,
including storage incidental to trans-
portation;
(2) The telephone number of a person
who is either knowledgeable of the haz-
ardous material being shipped and has
comprehensive emergency response and
incident mitigation information for
that material, or has immediate access
to a person who possesses such knowl-
edge and information. A telephone
number that requires a call back (such
as an answering service, answering ma-
chine, or beeper device) does not meet
the requirements of paragraph (a) of
this section; and
(3) Entered on a shipping paper, as
follows:
(i) Immediately following the de-
scription of the hazardous material re-
quired by subpart C of this part; or
(ii) Entered once on the shipping
paper in the manner prescribed in para-
graph (b) of this section in a promi-
nent, readily identifiable, and clearly
visible manner that allows the infor-
mation to be easily and quickly found,
such as by highlighting, use of a larger
font or a font that is a different color
from other text and information, or
otherwise setting the information
apart to provide for quick and easy rec-
ognition. The offeror may use one of
the methods prescribed in this para-
graph only if the telephone number ap-
plies to each hazardous material en-
tered on the shipping paper, and if it is
indicated that the telephone number is
for emergency response information
(for example: ‘‘EMERGENCY CON-
TACT: * * *’’).
(b) The telephone number required by
paragraph (a) of this section must be –
(1) The number of the person offering
the hazardous material for transpor-
tation when that person is also the
emergency response information pro-
vider (ERI provider). The name of the
person, or contract number or other
unique identifier assigned by an ERI
provider, identified with the emer-
gency response telephone number must
455
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.606
be entered on the shipping paper imme-
diately before, after, above, or below
the emergency response telephone
number unless the name is entered
elsewhere on the shipping paper in a
prominent, readily identifiable, and
clearly visible manner that allows the
information to be easily and quickly
found; or
(2) The number of an agency or orga-
nization capable of, and accepting re-
sponsibility for, providing the detailed
information required by paragraph
(a)(2) of this section. The person who is
registered with the ERI provider must
ensure that the agency or organization
has received current information on
the material before it is offered for
transportation. The person who is reg-
istered with the ERI provider must be
identified by name, or contract number
or other unique identifier assigned by
the ERI provider, on the shipping paper
immediately before, after, above, or
below the emergency response tele-
phone number in a prominent, readily
identifiable, and clearly visible manner
that allows the information to be eas-
ily and quickly found, unless the name
or identifier is entered elsewhere in a
prominent manner as provided in para-
graph (b)(1) of this section.
(c) A person preparing shipping pa-
pers for continued transportation in
commerce must include the informa-
tion required by this section. If the
person preparing shipping papers for
continued transportation in commerce
elects to assume responsibility for pro-
viding the emergency response tele-
phone number required by this section,
the person must ensure that all the re-
quirements of this section are met.
(d) The requirements of this section
do not apply to—
(1) Hazardous materials that are of-
fered for transportation under the pro-
visions applicable to limited quantities
or excepted quantities; or
(2) Materials properly described
under the following shipping names:

§ 172.802
Components of a security
plan.
(a) The security plan must include an
assessment of transportation security
risks for shipments of the hazardous
materials listed in § 172.800, including
site-specific or location-specific risks
associated with facilities at which the
hazardous materials listed in § 172.800
are prepared for transportation, stored,
or unloaded incidental to movement,
and appropriate measures to address
the assessed risks. Specific measures
put into place by the plan may vary
commensurate with the level of threat
at a particular time. At a minimum, a
security plan must include the fol-
lowing elements:
(1)
Personnel security.
Measures to
confirm information provided by job
applicants hired for positions that in-
volve access to and handling of the haz-
ardous materials covered by the secu-
rity plan. Such confirmation system
must be consistent with applicable
Federal and State laws and require-
ments concerning employment prac-
tices and individual privacy.
(2)
Unauthorized access.
Measures to
address the assessed risk that unau-
thorized persons may gain access to
the hazardous materials covered by the
security plan or transport conveyances
being prepared for transportation of
the hazardous materials covered by the
security plan.
(3)
En route security.
Measures to ad-
dress the assessed security risks of
shipments of hazardous materials cov-
ered by the security plan en route from
origin to destination, including ship-
ments stored incidental to movement.
(b) The security plan must also in-
clude the following:
(1) Identification by job title of the
senior management official responsible
for overall development and implemen-
tation of the security plan;
(2) Security duties for each position
or department that is responsible for
implementing the plan or a portion of
the plan and the process of notifying
employees when specific elements of
the security plan must be imple-
mented; and
(3) A plan for training hazmat em-
ployees in accordance with § 172.704
(a)(4) and (a)(5) of this part.
(c) The security plan, including the
transportation security risk assess-
ment developed in accordance with
paragraph (a) of this section, must be
in writing and must be retained for as
long as it remains in effect. The secu-
rity plan must be reviewed at least an-
nually and revised and/or updated as
necessary to reflect changing cir-
cumstances. The most recent version of
the security plan, or portions thereof,
must be available to the employees
who are responsible for implementing
it, consistent with personnel security
clearance or background investigation
460
49 CFR Ch. I (10–1–23 Edition)
§ 172.804
restrictions and a demonstrated need
to know. When the security plan is up-
dated or revised, all employees respon-
sible for implementing it must be noti-
fied and all copies of the plan must be
maintained as of the date of the most
recent revision.
(d) Each person required to develop
and implement a security plan in ac-
cordance with this subpart must main-
tain a copy of the security plan (or an
electronic file thereof) that is acces-
sible at, or through, its principal place
of business and must make the security
plan available upon request, at a rea-
sonable time and location, to an au-
thorized official of the Department of

§ 172.804
Relationship to other Federal
requirements.
To avoid unnecessary duplication of
security requirements, security plans
that conform to regulations, standards,
protocols, or guidelines issued by other
Federal agencies, international organi-
zations, or industry organizations may
be used to satisfy the requirements in
this subpart, provided such security
plans address the requirements speci-
fied in this subpart.
§ 172.820
Additional planning require-
ments for transportation by rail.
(a)
General.
Each rail carrier trans-
porting in commerce one or more of
the following materials is subject to
the additional safety and security plan-
ning requirements of this section:
(1) More than 2,268 kg (5,000 lbs.) in a
single carload of a Division 1.1, 1.2 or
1.3 explosive;
(2) A quantity of a material poi-
sonous by inhalation in a single bulk
packaging;
(3) A highway route-controlled quan-
tity of a Class 7 (radioactive) material,
as defined in § 173.403 of this sub-
chapter;
(4) A high-hazard flammable train
(HHFT) as defined in § 171.8 of this sub-
chapter; or
(5) A quantity of UN1972 (Methane,
refrigerated liquid or Natural gas, re-
frigerated liquid) when transported in a
rail tank car.
(b) Not later than 90 days after the
end of each calendar year, a rail carrier
must compile commodity data for the
previous calendar year for the mate-
rials listed in paragraph (a) of this sec-
tion. The following stipulations apply
to data collected:
(1) Commodity data must be col-
lected by route, a line segment or se-
ries of line segments as aggregated by
the rail carrier. Within the rail carrier
selected route, the commodity data
must identify the geographic location
of the route and the total number of
shipments by UN identification number
for the materials specified in para-
graph (a) of this section.
(i) A rail carrier subject to additional
planning requirements of this section
based on paragraph (a)(5) of this sec-
tion that has yet to transport UN 1972,
must factor in planned shipments of
UN 1972 to the commodity data for use
in the paragraph (c) route analysis
prior to initial transport of the mate-
rial.
(ii) [Reserved]
(2) A carrier may compile commodity
data, by UN number, for all Class 7 ma-
terials transported (instead of only
highway route controlled quantities of
Class 7 materials) and for all Division
6.1 materials transported (instead of
only Division 6.1 poison inhalation haz-
ard materials).
(c)
Rail transportation route analysis.
For each calendar year, a rail carrier
must analyze the safety and security
risks for the transportation route(s),
identified in the commodity data col-
lected as required by paragraph (b) of
this section. The route analysis must
be in writing and include the factors
contained in appendix D to this part, as
applicable.
(1) The safety and security risks
present must be analyzed for the route
and railroad facilities along the route.
For purposes of this section, railroad
facilities are railroad property includ-
ing, but not limited to, classification
and switching yards, storage facilities,
and non-private sidings. This term does
not include an offeror’s facility, pri-
vate track, private siding, or con-
signee’s facility.
(2) In performing the analysis re-
quired by this paragraph, the rail car-
rier must seek relevant information
461
Pipeline and Haz. Matls. Safety Admin., DOT
§ 172.820
from state, local, and tribal officials,
as appropriate, regarding security risks
to high-consequence targets along or in
proximity to the route(s) utilized. If a
rail carrier is unable to acquire rel-
evant information from state, local, or
tribal officials, then it must document
that in its analysis. For purposes of
this section, a high-consequence target
means a property, natural resource, lo-
cation, area, or other target designated
by the Secretary of Homeland Security
that is a viable terrorist target of na-
tional significance, the attack of which
by railroad could result in catastrophic
loss of life, significant damage to na-
tional security or defense capabilities,
or national economic harm.
(d)
Alternative route analysis.
(1) For
each calendar year, a rail carrier must
identify practicable alternative routes
over which it has authority to operate,
if an alternative exists, as an alter-
native route for each of the transpor-
tation routes analyzed in accordance
with paragraph (c) of this section. The
carrier must perform a safety and secu-
rity risk assessment of the alternative
routes for comparison to the route
analysis prescribed in paragraph (c) of
this section. The alternative route
analysis must be in writing and include
the criteria in appendix D of this part.
When determining practicable alter-
native routes, the rail carrier must
consider the use of interchange agree-
ments with other rail carriers. The
written alternative route analysis
must also consider:
(i) Safety and security risks pre-
sented by use of the alternative
route(s);
(ii) Comparison of the safety and se-
curity risks of the alternative(s) to the
primary rail transportation route, in-
cluding the risk of a catastrophic re-
lease from a shipment traveling along
each route;
(iii) Any remediation or mitigation
measures implemented on the primary
or alternative route(s); and
(iv) Potential economic effects of
using the alternative route(s), includ-
ing but not limited to the economics of
the commodity, route, and customer
relationship.
(2) In performing the analysis re-
quired by this paragraph, the rail car-
rier should seek relevant information
from state, local, and tribal officials,
as appropriate, regarding security risks
to high-consequence targets along or in
proximity to the alternative routes. If
a rail carrier determines that it is not
appropriate to seek such relevant in-
formation, then it must explain its rea-
soning for that determination in its
analysis.
(e)
Route Selection.
A carrier must use
the analysis performed as required by
paragraphs (c) and (d) of this section to
select the route to be used in moving
the materials covered by paragraph (a)
of this section. The carrier must con-
sider any remediation measures imple-
mented on a route. Using this process,
the carrier must at least annually re-
view and select the practicable route
posing the least overall safety and se-
curity risk. The rail carrier must re-
tain in writing all route review and se-
lection decision documentation and re-
strict the distribution, disclosure, and
availability of information contained
in the route analysis to covered per-
sons with a need-to-know, as described
in parts 15 and 1520 of this title. This
documentation should include, but is
not limited to, comparative analyses,
charts, graphics or rail system maps.
(f)
Completion of route analysis.
(1) The
rail transportation route analysis, al-
ternative route analysis, and route se-
lection process required under para-
graphs (c), (d), and (e) of this section
must be completed no later than the
end of the calendar year following the
year to which the analyses apply.
(2) The initial analysis and route se-
lection determinations required under
paragraphs (c), (d), and (e) of this sec-
tion must include a comprehensive re-
view of the entire system. Subsequent
analyses and route selection deter-
minations required under paragraphs
(c), (d), and (e) of this section must in-
clude a comprehensive, system-wide re-
view of all operational changes, infra-
structure modifications, traffic adjust-
ments, changes in the nature of high-
consequence targets located along, or
in proximity to, the route, and any
other changes affecting the safety or
security of the movements of the mate-
rials specified in paragraph (a) of this
section that were implemented during
the calendar year.
462
49 CFR Ch. I (10–1–23 Edition)
§ 172.822
(3) A rail carrier need not perform a
rail transportation route analysis, al-
ternative route analysis, or route se-
lection process for any hazardous ma-
terial other than the materials speci-
fied in paragraph (a) of this section.
(g)
Rail carrier point of contact on rout-
ing issues.
Each rail carrier must iden-
tify a point of contact (including the
name, title, phone number and e-mail
address) on routing issues involving
the movement of materials covered by
this section in its security plan and
provide this information to:
(1) State and/or regional Fusion Cen-
ters that have been established to co-
ordinate with state, local and tribal of-
ficials on security issues and which are
located within the area encompassed
by the rail carrier’s rail system; and
(2) State, local, and tribal officials in
jurisdictions that may be affected by a
rail carrier’s routing decisions and who
directly contact the railroad to discuss
routing decisions.
(h)
Storage, delays in transit, and noti-
fication.
With respect to the materials
specified in paragraph (a) of this sec-
tion, each rail carrier must ensure the
safety and security plan it develops
and implements under this subpart in-
cludes all of the following:
(1) A procedure under which the rail
carrier must consult with offerors and
consignees in order to develop meas-
ures for minimizing, to the extent
practicable, the duration of any stor-
age of the material incidental to move-
ment (see § 171.8 of this subchapter).
(2) Measures to prevent unauthorized
access to the materials during storage
or delays in transit.
(3) Measures to mitigate risk to pop-
ulation centers associated with in-
transit storage.
(4) Measures to be taken in the event
of an escalating threat level for mate-
rials stored in transit.
(5) Procedures for notifying the con-
signee in the event of a significant
delay during transportation; such noti-
fication must be completed within 48
hours after the carrier has identified
the delay and must include a revised
delivery schedule. A significant delay
is one that compromises the safety or
security of the hazardous material or
delays the shipment beyond its normal
expected or planned shipping time. No-
tification should be made by a method
acceptable to both the rail carrier and
consignee.
(i)
Recordkeeping.
(1) Each rail carrier
must maintain a copy of the informa-
tion specified in paragraphs (b), (c), (d),
(e), and (f) of this section (or an elec-
tronic image thereof) that is accessible
at, or through, its principal place of
business and must make the record
available upon request, at a reasonable
time and location, to an authorized of-
ficial of the Department of Transpor-
tation or the Department of Homeland
Security. Records must be retained for
a minimum of two years.
(2) Each rail carrier must restrict the
distribution, disclosure, and avail-
ability of information collected or de-
veloped in accordance with paragraphs
(c), (d), (e), and (f) of this section to
covered persons with a need-to-know,
as described in parts 15 and 1520 of this
title.
(j)
Compliance and enforcement.
If the
carrier’s route selection documenta-
tion and underlying analyses are found
to be deficient, the carrier may be re-
quired to revise the analyses or make
changes in route selection. If DOT finds
that a chosen route is not the safest
and most secure practicable route
available, the FRA Associate Adminis-
trator for Safety, in consultation with
TSA, may require the use of an alter-
native route. Prior to making such a
determination, FRA and TSA will con-
sult with the Surface Transportation
Board (STB) regarding whether the
contemplated alternative route(s)
would be economically practicable.

The following are Munsell notations and
Commission Internationale de L’Eclairage
(CIE) coordinates which describe the Office
of Hazardous Materials Transportation Label
and Placard Color Tolerance Charts in tables
1 and 2, and the CIE coordinates for the color
tolerances specified in table 3. Central colors
and tolerances described in table 2 approxi-
mate those described in table 1 while allow-
ing for differences in production methods
and materials used to manufacture labels
and placards surfaced with printing inks.
Primarily, the color charts based on table 1
are for label or placard colors applied as
opaque coatings such as paint, enamel or
plastic, whereas color charts based on table
2 are intended for use with labels and plac-
ards surfaced only with inks.
For labels printed directly on packaging
surfaces, table 3 may be used, although com-
pliance with either table 1 or table 2 is suffi-
cient. However, if visual reference indicates
that the colors of labels printed directly on
package surfaces are outside the table 1 or 2
tolerances, a spectrophotometer or other in-
strumentation may be required to insure
compliance with table 3.

Maximum chroma is not limited.

For the colors green and purple, the minimum saturation (chroma) limits for porcelain enamel on metal are lower than for
most other surface coatings. Therefore, the minimum chroma limits of these two colors as displayed on the Charts for compari-
son to porcelain enamel on metal is low, as shown for green (grayish B) and purple (gray).

A. This appendix sets forth the minimum
criteria that must be considered by rail car-
riers when performing the safety and secu-
rity risk analyses required by § 172.820. The
risk analysis to be performed may be quan-
titative, qualitative, or a combination of
both. In addition to clearly identifying the
hazardous material(s) and route(s) being ana-
lyzed, the analysis must provide a thorough
468
49 CFR Ch. I (10–1–23 Edition)
Pt. 173
description of the threats, identified
vulnerabilities, and mitigation measures im-
plemented to address identified
vulnerabilities.
B. In evaluating the safety and security of
hazardous materials transport, selection of
the route for transportation is critical. For
the purpose of rail transportation route
analysis, as specified in § 172.820(c) and (d), a
route may include the point where the car-
rier takes possession of the material and all
track and railroad facilities up to the point
where the material is relinquished to an-
other entity. Railroad facilities are railroad
property including, but not limited to, clas-
sification and switching yards, storage fa-
cilities, and non-private sidings; however,
they do not include an offeror’s facility, pri-
vate track, private siding, or consignee’s fa-
cility. Each rail carrier must use best efforts
to communicate with its shippers, con-
signees, and interlining partners to ensure
the safety and security of shipments during
all stages of transportation.
C. Because of the varying operating envi-
ronments and interconnected nature of the
rail system, each carrier must select and
document the analysis method/model used
and identify the routes to be analyzed.
D. The safety and security risk analysis
must consider current data and information
as well as changes that may reasonably be
anticipated to occur during the analysis
year. Factors to be considered in the per-
formance of this safety and security risk
analysis include:
1. Volume of hazardous material trans-
ported;
2. Rail traffic density;
3. Trip length for route;
4. Presence and characteristics of railroad
facilities;
5. Track type, class, and maintenance
schedule;
6. Track grade and curvature;
7. Presence or absence of signals and train
control systems along the route (‘‘dark’’
versus signaled territory);
8. Presence or absence of wayside hazard
detectors;
9. Number and types of grade crossings;
10. Single versus double track territory;
11. Frequency and location of track turn-
outs;
12. Proximity to iconic targets;
13. Environmentally sensitive or signifi-
cant areas;
14. Population density along the route;
15. Venues along the route (stations,
events, places of congregation);
16. Emergency response capability along
the route;
17. Areas of high consequence along the
route, including high consequence targets as
defined in § 172.820(c);
18. Presence of passenger traffic along
route (shared track);
19. Speed of train operations;
20. Proximity to en-route storage or repair
facilities;
21. Known threats, including any non-pub-
lic threat scenarios provided by the Depart-
ment of Homeland Security or the Depart-
ment of Transportation for carrier use in the
development of the route assessment;
22. Measures in place to address apparent
safety and security risks;
23. Availability of practicable alternative
routes;
24. Past incidents;
25. Overall times in transit;
26. Training and skill level of crews; and
27. Impact on rail network traffic and con-
gestion.
