49 CFR Ch. I (10–1–18 Edition)
§ 172.102
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, well-
ventilated place away from sources of heat.
160
This entry applies to safety devices for
vehicles, vessels or aircraft,
e.g.
air bag in-
flators, air bag modules, seat-belt
pretensioners, and pyromechanical devices
containing Class 1 (explosive) materials or
materials of other hazard classes. These ar-
ticles must be tested in accordance with
Test series 6(c) of Part I of the UN Manual
of Tests and Criteria (incorporated by ref-
erence; see § 171.7 of this subchapter), with
no explosion of the device, no fragmenta-
tion of device casing or pressure vessel,
and no projection hazard or thermal effect
that would significantly hinder fire-fight-
ing or other emergency response efforts in
the immediate vicinity. If the air bag in-
flator 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 de-
scribed in § 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 ship-
ping description.
163
Substances must satisfactorily pass
Test Series 8 of the UN Manual of Tests
and Criteria, Part I, Section 18 (IBR, see
§ 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 § 171.7 of this sub-
chapter). 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 tem-
peratures. Decomposition can be initiated
by heat, moisture or by impurities (e.g.,
powdered metals (iron, manganese, cobalt,
magnesium)). During the course of trans-
portation, 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 mate-
rial.
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 com-
ponents 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
§ 171.8 of this subchapter), rep-
resentative samples of each new lighter de-
sign must be examined and successfully
tested as specified in § 173.308(b)(3). For cri-
teria in determining what is a new lighter
design,
see
§ 173.308(b)(1). For transpor-
tation of new lighter design samples for ex-
amination and testing,
see
§ 173.308(b)(2).
The examination and testing of each light-
er 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
§ 173.308(a)(4). For continued use of approv-
als dated prior to January 1, 2012,
see
§ 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 Adminis-
trator prior to being offered for transpor-
tation or transported in commerce. In
addition, a lighter design intended to
contain a non-pressurized Class 3 mate-
rial is excepted from the examination
and testing criteria specified in
§ 173.308(b)(3). An unused lighter or a
lighter that is cleaned of residue and
purged of vapors is not subject to the re-
quirements of this subchapter.
169
This entry applies to lighter refills (
see
§ 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 con-
tained therein. In addition, a container ex-
ceeding 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 § 173.306(h) of this subchapter.
170
Air must be eliminated from the vapor
space by nitrogen or other means.
