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 [deg]C (5 [deg]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 material must be packaged in accordance with
packing method OP6 in Sec. 173.225 of this subchapter. If the SADT of
the technically pure substance is higher than 75 [deg]C, the technically
pure substance and formulations derived from it are not self-reactive
materials and, if not meeting any other hazard class, are not subject to
the requirements of this subchapter.
39 This substance may be carried under provisions 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 exceed 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 Sec. 171.7 of this subchapter).
40 Polyester resin kits consist of two components: a base material
(Class 3, Packing Group II or III) and an activator (organic peroxide),
each separately packed in an inner packaging. The organic peroxide must
be type D, E, or F, not requiring temperature control, and be limited to
a quantity of 125 mL (4.22 ounces) per inner packaging if liquid, and
500 g (1 pound) if solid. The components may be placed in the same outer
packaging provided they will not interact dangerously in the event of
leakage. Packing group will be II or III, according to the criteria for
Class 3, applied to the base material.
43 The membrane filters, including paper separators and coating or
backing materials, 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 Sec.
171.7 of this subchapter). 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, subsection 33.2.1 (IBR, see
Sec. 171.7 of this subchapter), nitrocellulose membrane filters in the
form in which they are to be transported that do not meet the criteria
for a Division 4.1 material are not subject to the requirements of this
subchapter. Packagings must be so constructed that explosion is not
possible by reason of increased internal pressure. Nitrocellulose
membrane filters covered by this entry, each with a mass not exceeding
0.5 g, are not subject to the requirements of this subchapter 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 neither 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
Manual of Tests and Criteria (IBR, see Sec. 171.7 of this subchapter),
nor classed as a Division 4.1 (flammable solid) when tested in
accordance with the procedures specified in Sec. 173.124 of this
subchapter (chips, if necessary, 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 between 18 [deg]C (64.4 [deg]F) and
40 [deg]C (104 [deg]F). Tanks containing solidified methacrylic acid
must not be reheated during transport.
46 This material must be packed in accordance with packing method OP6
(see Sec. 173.225 of this subchapter). During transport, it must be
protected from direct sunshine and stored (or kept) in a cool and well-
ventilated 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, each
packaging must correspond to a design type that has passed a
leakproofness test at the Packing Group II level. Small inner packagings
consisting of sealed packets containing less than 10 mL of a Class 3
liquid in Packing Group II or
[[Page 331]]
III absorbed into a solid material are not subject to this subchapter
provided there is no free liquid in the packet.
48 Mixtures of solids which are not subject to this subchapter and toxic
liquids may be transported under this entry without first applying the
classification criteria of Division 6.1, 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. Each packaging must correspond to
a design type that has passed a leakproofness test at the Packing Group
II level. This entry may not be used for solids containing a Packing
Group I liquid.
49 Mixtures of solids which are not subject to this subchapter and
corrosive liquids may be transported under this entry without first
applying the classification criteria of Class 8, 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. Each packaging must
correspond to a design type that has passed a leakproofness test at the
Packing Group II level.
50 Cases, cartridge, empty with primer which are made of metallic or
plastic casings and meeting the classification criteria of Division 1.4
are not regulated for domestic transportation.
51 This description applies to items previously described as ``Toy
propellant devices, Class C'' and includes reloadable kits. Model rocket
motors containing 30 grams or less propellant are classed as Division
1.4S and items containing more than 30 grams of propellant but not more
than 62.5 grams of propellant are classed as Division 1.4C.
52 This entry may only be used for substances that do not exhibit
explosive properties of Class 1 (explosive) when tested in accordance
with Test Series 1 and 2 of Class 1 (explosive) in the UN Manual of
Tests and Criteria, Part I (incorporated by reference; see Sec. 171.7
of this subchapter).
53 Packages of these materials must bear the subsidiary risk label,
``EXPLOSIVE'', and the subsidiary hazard class/division must be entered
in parentheses immediately following the primary hazard class in the
shipping description, unless otherwise provided in this subchapter or
through an approval issued by the Associate Administrator, or the
competent authority of the country of origin. A copy of the approval
shall accompany the shipping papers.
54 Maneb or maneb preparations not meeting the definition of Division
4.3 or any other hazard class are not subject to the requirements of
this subchapter when transported by motor vehicle, rail car, or
aircraft.

subchapter by the Associate Administrator.
56 A means to interrupt and prevent detonation of the detonator from
initiating the detonating cord must be installed between each electric
detonator and the detonating cord ends of the jet perforating guns
before the charged jet perforating guns are offered for transportation.
57 Maneb or Maneb preparations stabilized against self-heating need not
be classified in Division 4.2 when it can be demonstrated by testing
that a volume of 1 m3 of substance does not self-ignite and
that the temperature at the center of the sample does not exceed 200
[deg]C, when the sample is maintained at a temperature of not less than
75 [deg]C 2 [deg]C for a period of 24 hours, in
accordance with procedures set forth for testing self-heating materials
in the UN Manual of Tests and Criteria (IBR, see Sec. 171.7 of this
subchapter).
58 Aqueous solutions of Division 5.1 inorganic solid nitrate substances
are considered as not meeting the criteria of Division 5.1 if the
concentration of the substances in solution at the minimum temperature
encountered in transport is not greater than 80% of the saturation
limit.
59 Ferrocerium, stabilized against corrosion, with a minimum iron
content of 10 percent is not subject to the requirements of this
subchapter.
60 After September 30, 1997, an oxygen generator, chemical, that is
shipped with its means of initiation attached must incorporate at least
two positive means of preventing unintentional actuation of the
generator, and be classed and approved by the Associate Administrator.
The procedures for approval of a chemical oxygen generator that contains
an explosive means of initiation (e.g., a primer or electric match) are
specified in Sec. 173.56 of this subchapter. Each person who offers a
chemical oxygen generator for transportation after September 30, 1997,
shall: (1) ensure that it is offered in conformance with the conditions
of the approval; (2) maintain a copy of the approval at each facility

rubidium, and caesium.
65 The group of alkaline earth metals includes magnesium, calcium,
strontium, and barium.
[[Page 332]]
66 Formulations of these substances containing not less than 30 percent
non-volatile, non-flammable phlegmatizer are not subject to this
subchapter.
70 Black powder that has been classed in accordance with the
requirements of Sec. 173.56 of this subchapter may be reclassed and
offered for domestic transportation as a Division 4.1 material if it is
offered for transportation and transported in accordance with the
limitations and packaging requirements of Sec. 173.170 of this
subchapter.
74 During transport, this material must be protected from direct
sunshine and stored or kept in a cool and well-ventilated place, away
from all sources of heat.
77 For domestic transportation, a Division 5.1 subsidiary risk label is
required only if a carbon dioxide and oxygen mixture contains more than
23.5% oxygen.
78 This entry may not be used to describe compressed air which contains
more than 23.5 percent oxygen. An oxidizer label is not required for any
oxygen concentration of 23.5 percent or less.
79 This entry may not be used for mixtures that meet the definition for
oxidizing gas.
81 Polychlorinated biphenyl items, as defined in 40 CFR 761.3, for which
specification packagings are impractical, may be packaged in non-
specification packagings meeting the general packaging requirements of
subparts A and B of part 173 of 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 subchapter.
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 escape.The articles may be transported as in Division
1.4 Compatibility Group D (1.4D) if all of the conditions specified in
Sec. 173.63(a) of this subchapter are met.
103 Detonators 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 that more than 90 percent of
the devices tested in a package explode practically simultaneously.
Limited propagation means that if one detonator near the center of a
shipping package is exploded, the aggregate weight of explosives,
excluding ignition and delay charges, in this and all additional
detonators in the outside packaging that explode may not exceed 25
grams.
105 The word ``Agents'' may be used instead of ``Explosives'' when
approved by the Associate Administrator.
106 The recognized name of the particular explosive may be specified in
addition to the type.
107 The classification of the substance is expected 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 Sec. Sec. 173.57 and 173.58
of this subchapter.
108 Fireworks must be so constructed and packaged that loose pyrotechnic
composition will not be present in packages during transportation.
109 Rocket motors must be nonpropulsive in transportation unless
approved in accordance with Sec. 173.56 of this subchapter. A rocket
motor to be considered ``nonpropulsive'' 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 may include installed
actuating cartridges (cartridges, power device of Division 1.4C or
1.4S), without changing the classification of Division 2.2, provided the
aggregate quantity of deflagrating (propellant) explosives does not
exceed 3.2 grams per extinguishing unit.
111 Explosive substances of Division 1.1 Compatibility Group A (1.1A)
are forbidden for transportation if dry or not desensitized, unless
incorporated in a device.
113 The sample must be given a tentative approval by an agency or
laboratory in accordance with Sec. 173.56 of this subchapter.
114 Jet perforating guns, charged, oil well, without detonator may be
reclassed to Division 1.4 Compatibility Group D (1.4D) if the following
conditions are met:
a. The total weight of the explosive contents 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 Sec. 173.62 of this subchapter.
115 Boosters with detonator, detonator assemblies 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
propagation means that if one booster near the center of the package is
exploded, the aggregate weight of explosives, excluding ignition and
delay charges, in this and all additional boosters in the outside
packaging that explode may not exceed 25 g.
116 Fuzes, detonating may be classed in Division 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
[[Page 333]]
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 contained 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.
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, provided 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 Sec. 171.7 of this subchapter).
120 The phlegmatized substance must be significantly less sensitive than
dry PETN.
121 This substance, when containing less alcohol, water or phlegmatizer
than specified, may not be transported unless approved by the Associate
Administrator.
123 Any explosives, blasting, type C containing 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 mixtures 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 Sec. 171.7 of this subchapter) and
approved by the Associate Administrator. Testing must be conducted on at
least three packages as prepared for transport. Mixtures containing at
least 98%, by mass, of phlegmatizer are not subject to the requirements
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 organic materials transported
under this entry may not meet the definition and criteria of a Class 1
material. (See Sec. 173.50 of this subchapter.)
128 Regardless of the provisions of Sec. 172.101(c)(12), aluminum
smelting by-products 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 material and transported under this
entry. The presence of a Class 8 hazard must be communicated as required
by this Part for subsidiary hazards.
129 These materials may not be classified and transported unless
authorized by the Associate Administrator on the basis of results from
Series 2 Test and a Series 6(c) Test from the UN Manual of Tests and
Criteria (IBR, see Sec. 171.7 of this subchapter) on packages as
prepared for transport. The packing group assignment and packaging must
be approved by the Associate Administrator for Hazardous Materials
Safety on the basis of the criteria in Sec. 173.21 of this subchapter
and the package type used for the Series 6(c) test.
130 For other than a dry battery specifically covered by another entry
in the Sec. 172.101 Table, ``Batteries, dry'' are not subject to the
requirements of this subchapter when they are securely packaged and
offered for transportation in a manner that prevents the dangerous
evolution of heat (for example, by the effective insulation of exposed
terminals) and protects against short circuits.
131 This material may not be offered for transportation unless approved
by the Associate Administrator.
132 This entry may only be used for uniform, ammonium nitrate based
fertilizer mixtures, containing nitrogen, phosphate or potash, meeting
the following criteria: (1) Contains not more than 70% ammonium nitrate
