§ 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.

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
visible at the time the material is loaded

Pipeline and Haz. Matls. Safety Admin., DOT
§ 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

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.

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

‘‘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

document such as an air waybill accom-
panying the shipment.
(d)
Used or spent battery exception.
Used or
spent dry batteries of both non-recharge-
able and rechargeable designs, with a
marked rating up to 9-volt that are com-
bined in the same package and trans-
ported by highway or rail for recycling,
reconditioning, or disposal are not sub-
ject to this special provision or any other
requirement of the HMR. Note that bat-
teries utilizing different chemistries (
i.e.,
those battery chemistries specifically
covered by another entry in the § 172.101
Table) as well as dry batteries with a
marked rating greater than 9-volt may
not be combined with used or spent bat-
teries in the same package. Note also
that this exception does not apply to bat-
teries that have been reconditioned for
reuse.

becomes ineffective at lower temperatures
within the anticipated duration of trans-
port, temperature control is required and
is forbidden by aircraft. In making this de-
termination factors to be taken into con-
sideration include, but are not limited to,
the capacity and geometry of the pack-
aging and the effect of any insulation
present, the temperature of the material
when offered for transport, the duration of
the journey, and the ambient temperature
conditions typically encountered in the
journey (considering also the season of

TP19
The calculated wall thickness must
be increased by 3 mm at the time of con-
struction. Wall thickness must be verified
ultrasonically at intervals midway between
periodic hydraulic tests (every 2.5 years).
The portable tank must not be used if the
wall thickness is less than that prescribed by
the applicable T code in Column (7) of the
Table for this material.
TP20
This hazardous material must only
be transported in insulated tanks under a ni-
trogen blanket.
TP21
The wall thickness must not be less
than 8 mm. Portable tanks must be hydrau-
lically tested and internally inspected at in-
tervals not exceeding 2.5 years.
TP22
Lubricants for portable tank fit-
tings (for example, gaskets, shut-off valves,
flanges) must be oxygen compatible.
TP24
The portable tank may be fitted
with a device to prevent the build up of ex-
cess pressure due to the slow decomposition
of the hazardous material being transported.
The device must be in the vapor space when
the tank is filled under maximum filling
conditions. This device must also prevent an
unacceptable amount of leakage of liquid in
the case of overturning.
TP25
Sulphur trioxide 99.95% pure and
above may be transported in tanks without
an inhibitor provided that it is maintained
at a temperature equal to or above 32.5
°

§ 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
