Section 172.102

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

subchapter) have demonstrated that any
hazardous effects from accidental functioning are confined to within the package.
Effective January 1, 2014, for transportation domestically by highway or rail,
this entry may only be used if the results
of Test Series 6(d) of Part I of the UN Manual of Tests and Criteria (IBR, see Section 171.7 of
this subchapter) have demonstrated that
any hazardous effects from accidental
functioning are confined to within the
package. Testing must be performed or
witnessed by a person who is approved by
the Associate Administrator (see Section 173.56(b)
of this subchapter). All successfully conducted tests or reassignment to another
compatibility group require the issuance of
a new or revised approval by the Associate
Administrator prior to transportation on
or after the dates specified for each authorized mode of transport in this special provision.
349 Mixtures of hypochlorite with an ammonium salt are forbidden for transport. A
hypochlorite solution, UN1791, is a Class 8
corrosive material.
350 Ammonium bromate, ammonium bromate aqueous solutions, and mixtures of a
bromate with an ammonium salt are forbidden for transport.
351 Ammonium chlorate, ammonium chlorate aqueous solutions, and mixtures of a
chlorate with an ammonium salt are forbidden for transport.
352 Ammonium chlorite, ammonium chlorite aqueous solutions, and mixtures of a
chlorite with an ammonium salt are forbidden for transport.
353 Ammonium permanganate, ammonium
permanganate aqueous solutions, and mixtures of a permanganate with an ammonium salt are forbidden for transport.
357 A bulk packaging that emits hydrogen
sulfide in sufficient concentration that vapors evolved from the crude oil can present
an inhalation hazard must be marked as
specified in Section 172.327 of this part.
360 Vehicles only powered by lithium batteries must be assigned the identification
number UN3171.
361 Capacitors with an energy storage capacity of 0.3 Wh or less are not subject to
the requirements of this subchapter. Energy storage capacity means the energy
held by a capacitor, as calculated using the
nominal voltage and capacitance. This
entry does not apply to capacitors that by
design maintain a terminal voltage (e.g.,
asymmetrical capacitors.)
362 This entry applies to liquids, pastes or
powders, pressurized with a propellant that
meets the definition of a gas in Section 173.115. A
chemical under pressure packaged in an
aerosol dispenser must be transported
under UN1950. The chemical under pressure
must be classed based on the hazard characteristics of the components in the pro-

pellant; the liquid; or the solid. The following provisions also apply:
a. If one of the components, which can be
a pure substance or a mixture, is classed
as flammable, the chemical under pressure must be classed as flammable in Division 2.1. Flammable components are
flammable liquids and liquid mixtures,
flammable solids and solid mixtures or
flammable gases and gas mixtures meeting the following criteria:
(1) A flammable liquid is a liquid having a
flashpoint of not more than 93 SectionC (200 SectionF);
(2) A flammable solid is a solid that meets
the criteria in Section 173.124 of this subchapter;
or
(3) A flammable gas is a gas that meets the
criteria in Section 173.115 of this subchapter.
b. Gases of Division 2.3 and gases with a
subsidiary risk of 5.1 must not be used as
a propellant in a chemical under pressure.
c. Where the liquid or solid components are
classed as Division 6.1, Packing Group II
or III, or Class 8, Packing Group II or III,
the chemical under pressure must be assigned a subsidiary risk of Division 6.1 or
Class 8 and the appropriate identification
number must be assigned. Components
classed as Division 6.1, Packing Group I,
or Class 8, Packing Group I, must not be
offered for transportation and transported under this description.
d. A chemical under pressure with components meeting the properties of: Class 1
(explosives); Class 3 (liquid desensitized
explosives); Division 4.1 (self-reactive
substances and solid desensitized explosives); Division 4.2 (substances liable to
spontaneous combustion); Division 4.3
(substances which, in contact with
water, emit flammable gases or toxic
gases); Division 5.1 (oxidizing substances); Division 5.2 (organic peroxides);
Division 6.2 (Infectious substances); or,
Class 7 (Radioactive material), must not
be offered for transportation under this
description.
e. A description to which special provision
170 or TP7 is assigned in Column 7 of the
Section 172.101 Hazardous Materials Table, and
therefore requires air to be eliminated
from the package vapor space by nitrogen or other means, must not be offered
for transportation under this description.
f. Chemicals under pressure containing
components forbidden for transport on
both passenger and cargo aircraft in Columns (9A) and (9B) of the Section 172.101 Hazardous Materials Table must not be
transported by air.
