Section 172.102

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

this subchapter for inner packagings may
be increased to 5 kg (11 pounds).
159 This material must be protected from
direct sunshine and kept in a cool, wellventilated place away from sources of heat.
160 This entry applies to safety devices for
vehicles, vessels or aircraft, e.g. air bag inflators,
air
bag
modules,
seat-belt
pretensioners, and pyromechanical devices
containing Class 1 (explosive) materials or
materials of other hazard classes. These articles must be tested in accordance with
Test series 6(c) of Part I of the UN Manual
of Tests and Criteria (incorporated by reference; see Section 171.7 of this subchapter), with
no explosion of the device, no fragmentation of device casing or pressure vessel,
and no projection hazard or thermal effect
that would significantly hinder fire-fighting or other emergency response efforts in
the immediate vicinity. If the air bag inflator unit satisfactorily passes the series
6(c) test, it is not necessary to repeat the
test on the air bag module. This entry does
not apply to life saving appliances described in Section 173.219 (UN2990 and UN3072).
162 This material may be transported under
the provisions of Division 4.1 only if it is
packed so that at no time during transport
will the percentage of diluent fall below
the percentage that is stated in the shipping description.
163 Substances must satisfactorily pass
Test Series 8 of the UN Manual of Tests
and Criteria, Part I, Section 18 (IBR, see
Section 171.7 of this subchapter).
164 Substances must not be transported
under this entry unless approved by the
Associate Administrator on the basis of
the results of appropriate tests according
to Part I of the UN Manual of Tests and
Criteria (IBR, see Section 171.7 of this subchapter). The material must be packaged
so that the percentage of diluent does not
fall below that stated in the approval at
any time during transportation.
165 These substances are susceptible to
exothermic decomposition at elevated temperatures. Decomposition can be initiated
by heat, moisture or by impurities (e.g.,
powdered metals (iron, manganese, cobalt,
magnesium)). During the course of transportation, these substances must be shaded
from direct sunlight and all sources of heat
and be placed in adequately ventilated
areas.
166 When transported in non-friable tablet
form, calcium hypochlorite, dry, may be
transported as a Packing Group III material.
167 These storage systems must always be
considered as containing hydrogen. A
metal hydride storage system installed in
or intended to be installed in a vehicle or
equipment or in vehicle or equipment components must be approved for transport by

the Associate Administrator. A copy of the
approval must accompany each shipment.
168 For lighters containing a Division 2.1
gas (see Section 171.8 of this subchapter), representative samples of each new lighter design must be examined and successfully
tested as specified in Section 173.308(b)(3). For criteria in determining what is a new lighter
design, see Section 173.308(b)(1). For transportation of new lighter design samples for examination and testing, see Section 173.308(b)(2).
The examination and testing of each lighter design must be performed by a person
authorized by the Associate Administrator
under the provisions of subpart E of part
107 of this chapter, as specified in
Section 173.308(a)(4). For continued use of approvals dated prior to January 1, 2012, see
Section 173.308(b)(5).
For non-pressurized lighters containing a
Class 3 (flammable liquid) material, its
design, description, and packaging must
be approved by the Associate Administrator prior to being offered for transportation or transported in commerce. In
addition, a lighter design intended to
contain a non-pressurized Class 3 material is excepted from the examination
and
testing
criteria
specified
in
Section 173.308(b)(3). An unused lighter or a
lighter that is cleaned of residue and
purged of vapors is not subject to the requirements of this subchapter.
169 This entry applies to lighter refills (see
Section 171.8 of this subchapter) that contain a
Division 2.1 (flammable) gas but do not
contain an ignition device. Lighter refills
offered for transportation under this entry
may not exceed 4 fluid ounces capacity
(7.22 cubic inches) or contain more than 65
grams of fuel. A lighter refill exceeding 4
fluid ounces capacity (7.22 cubic inches) or
containing more than 65 grams of fuel
must be classed as a Division 2.1 material,
described with the proper shipping name
appropriate for the material, and packaged
in the packaging specified in part 173 of
this subchapter for the flammable gas contained therein. In addition, a container exceeding 4 fluid ounces volumetric capacity
(7.22 cubic inches) or containing more than
65 grams of fuel may not be connected or
manifolded to a lighter or similar device
and must also be described and packaged
according to the fuel contained therein.
For transportation by passenger-carrying
aircraft, the net mass of lighter refills may
not exceed 1 kg per package, and, for
cargo-only aircraft, the net mass of lighter
refills may not exceed 15 kg per package.
See Section 173.306(h) of this subchapter.
170 Air must be eliminated from the vapor
space by nitrogen or other means.
