Section 172.102

49 CFR Ch. I (10-1-18 Edition)

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 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 (see UN0143 or UN0150 as appropriate).
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 Section 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 Section 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 Section 173.50 of
this subchapter.)
128 Regardless
of
the
provisions
of
Section 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 re-

sults from Series 2 Test and a Series 6(c)
Test from the UN Manual of Tests and Criteria (IBR, see Section 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 Section 173.21 of this
subchapter and the package type used for
the Series 6(c) test.
130  - Batteries, dry, sealed, n.o.s., -  commonly referred to as dry batteries, are hermetically sealed and generally utilize metals (other than lead) and/or carbon as electrodes. These batteries are typically used
for portable power applications. The rechargeable (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 batteries specifically covered by another
entry in the Section 172.101 Table must be transported in accordance with the requirements applicable to that entry. For example, nickel-metal hydride batteries transported by vessel in certain quantities are
covered by another entry (see Batteries,
nickel-metal hydride, UN3496). Dry batteries not specifically covered by another
entry in the Section 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 accordance with Section 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, scorching of packaging, or other evidence) occurs as a direct result of a dry battery.
For all modes of transportation, a written report submitted, retained, and updated in accordance with Section 171.16 is required if a fire, violent rupture, explosion
or dangerous evolution of heat occurs as
a direct result of a dry battery or battery-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 limited to the following methods:
(i) Packaging each battery or each batterypowered device when practicable, in fully
enclosed inner packagings made of nonconductive material;
(ii) Separating or packaging batteries in a
manner to prevent contact with other
batteries, devices or conductive materials (e.g., metal) in the packagings; or
