49 CFR Ch. I (10–1–18 Edition)
§ 172.102
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
