§ 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 
amended by Amdt. 172–32, 41 FR 38179, Sept. 
9, 1976] 

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 

background image

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 

background image

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.

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

§ 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

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

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 

background image

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.

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.

(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.

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.

§ 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.

permanganate, the transport of which is 
prohibited except when approved by the 
Associate Administrator. 

28 The dihydrated sodium salt of 

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

The commercial grade of calcium nitrate 

fertilizer, when consisting mainly of a dou-
ble salt (calcium nitrate and ammonium 
nitrate) containing not more than 10 per-
cent ammonium nitrate and at least 12 per-
cent water of crystallization, is not subject 
to the requirements of this subchapter.

§ 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

Mixtures of solids that are not subject to 

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 
applying the classification criteria of Divi-
sion 6.1, provided there is no free liquid

§ 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

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

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). 

Fertilizers meeting the criteria for this 
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 
in equipment’’ or ‘‘Lithium metal bat-
teries packed with equipment’’ or ‘‘Lith-

§ 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 

background image

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.

§ 172.203

Additional description re-

quirements. 

(a) 

Special permits. 

Except as provided 

in § 173.23 of this subchapter, each ship-
ping paper issued in connection with a 
shipment made under a special permit 
must bear the notation ‘‘DOT–SP’’ fol-
lowed by the special permit number as-
signed and located so that the notation 
is clearly associated with the descrip-
tion to which the special permit ap-
plies. Each shipping paper issued in 
connection with a shipment made 
under an exemption or special permit 
issued prior to October 1, 2007, may 
bear the notation ‘‘DOT–E’’ followed by 
the number assigned and so located 
that the notation is clearly associated 
with the description to which it ap-
plies. 

(b) 

Limited quantities. 

When a ship-

ping paper is required by this sub-
chapter, the description for a material 
offered for transportation as ‘‘limited 
quantity,’’ as authorized by this sub-
chapter, must include the words ‘‘Lim-
ited Quantity’’ or ‘‘Ltd Qty’’ following 
the basic description. 

(c) 

Hazardous substances. 

(1) Except 

for Class 7 (radioactive) materials de-
scribed in accordance with paragraph 
(d) of this section, if the proper ship-
ping name for a material that is a haz-
ardous substance does not identify the 
hazardous substance by name, the 
name of the hazardous substance must 
be entered in parentheses in associa-
tion with the basic description. If the 
material contains two or more haz-
ardous substances, at least two haz-
ardous substances, including the two 
with the lowest reportable quantities 
(RQs), must be identified. For a haz-
ardous waste, the waste code (e.g.,

§ 172.300 

(C) The last rail transporter des-

ignated to handle the waste in the 
United States; and 

(iv) Retain one copy of the manifest 

and rail shipping paper in accordance 
with 40 CFR 263.22. 

(2) Rail transporters must ensure 

that a shipping paper containing all 
the information required on the mani-
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-

the handwritten signature of the next 
non-rail transporter on the manifest; 
and 

(ii) Retain a copy of the manifest in 

accordance with 40 CFR 263.22. 

(5) Before accepting hazardous waste 

from a rail transporter, a non-rail

transporter. 

(g) The person delivering a hazardous 

waste to an initial rail carrier shall 
send a copy of the manifest, dated and 
signed by a representative of the rail 
carrier, to the person representing the 
designated facility. 

(h) A hazardous waste manifest re-

quired by 40 CFR part 262, containing 
all of the information required by this 
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-

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.

shipments by cargo vessel under char-
ter to DOD if at least one required 
label is displayed on each unitized or 
palletized load. 

(3) A package containing a hazardous 

material other than ammunition that 
is— 

(i) Loaded and unloaded under the su-

pervision of DOD personnel, and 

(ii) Escorted by DOD personnel in a 

separate vehicle. 

(4) A compressed gas cylinder perma-

nently mounted in or on a transport 
vehicle. 

(5) A freight container, aircraft unit 

load device or portable tank, which— 

(i) Is placarded in accordance with 

subpart F of this part, or 

(ii) Conforms to paragraph (a)(3) or

radioactive material and surface con-
taminated objects, when transported 
under § 173.427(a)(6)(vi) of this sub-
chapter. 

(8) Packages containing toy plastic 

or paper caps for toy pistols described 
as ‘‘UN0349, Articles, explosive, n.o.s. 
(Toy caps), 1.4S’’ or ‘‘NA0337, Toy caps, 
1.4S’’ when offered in conformance with 
the conditions of § 172.102(c)(1), Special 
provision 382. 

(b) Certain exceptions to labeling re-

quirements are provided for small 
quantities and limited quantities in ap-
plicable sections in part 173 of this sub-
chapter. 

(c) Notwithstanding the provisions of

hazard label is not required on a pack-
age containing a Class 8 (corrosive) 
material which has a subsidiary hazard 
of Division 6.1 (poisonous) if the tox-
icity of the material is based solely on 
the corrosive destruction of tissue 
rather than systemic poisoning. In ad-
dition, a Division 4.1 subsidiary hazard 
label is not required on a package bear-
ing a Division 4.2 label. 

(d) A package containing a material 

poisonous by inhalation (see § 171.8 of 
this subchapter) in a closed transport

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.

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:

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

§ 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

§ 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 

background image

§ 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 

background image

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

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-

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)

§ 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 

background image

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 

background image

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: 

(i) Battery powered equipment. 
(ii) Battery powered vehicle.

§ 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 

background image

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 
Transportation or the Department of 
Homeland Security.

§ 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 

background image

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.

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.

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 

background image

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.
