49 CFR Ch. I (10–1–18 Edition) 

§ 172.102 

subchapter) have demonstrated that any 
hazardous effects from accidental func-
tioning are confined to within the package. 
Effective January 1, 2014, for transpor-
tation 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 Man-
ual of Tests and Criteria (IBR, 

see 

§ 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 

§ 173.56(b) 

of this subchapter). All successfully con-
ducted 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 author-
ized mode of transport in this special pro-
vision. 

349

Mixtures of hypochlorite with an ammo-

nium salt are forbidden for transport. A 
hypochlorite solution, UN1791, is a Class 8 
corrosive material. 

350

Ammonium bromate, ammonium bro-

mate aqueous solutions, and mixtures of a 
bromate with an ammonium salt are for-
bidden for transport. 

351

Ammonium chlorate, ammonium chlo-

rate aqueous solutions, and mixtures of a 
chlorate with an ammonium salt are for-
bidden for transport. 

352

Ammonium chlorite, ammonium chlo-

rite aqueous solutions, and mixtures of a 
chlorite with an ammonium salt are for-
bidden for transport. 

353

Ammonium permanganate, ammonium 

permanganate aqueous solutions, and mix-
tures of a permanganate with an ammo-
nium salt are forbidden for transport. 

357

A bulk packaging that emits hydrogen 

sulfide in sufficient concentration that va-
pors evolved from the crude oil can present 
an inhalation hazard must be marked as 
specified in § 172.327 of this part. 

360

Vehicles only powered by lithium bat-

teries must be assigned the identification 
number UN3171. 

361

Capacitors with an energy storage ca-

pacity of 0.3 Wh or less are not subject to 
the requirements of this subchapter. En-
ergy 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 § 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 char-
acteristics of the components in the pro-

pellant; the liquid; or the solid. The fol-
lowing 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 pres-
sure must be classed as flammable in Di-
vision 2.1. Flammable components are 
flammable liquids and liquid mixtures, 
flammable solids and solid mixtures or 
flammable gases and gas mixtures meet-
ing the following criteria: 

(1) A flammable liquid is a liquid having a 

flashpoint of not more than 93 

°

C (200 

°

F); 

(2) A flammable solid is a solid that meets 

the criteria in § 173.124 of this subchapter; 
or 

(3) A flammable gas is a gas that meets the 

criteria in § 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 pres-
sure. 

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 as-
signed 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 trans-
ported under this description. 

d. A chemical under pressure with compo-

nents meeting the properties of: Class 1 
(explosives); Class 3 (liquid desensitized 
explosives); Division 4.1 (self-reactive 
substances and solid desensitized explo-
sives); 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 sub-
stances); 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 
§ 172.101 Hazardous Materials Table, and 
therefore requires air to be eliminated 
from the package vapor space by nitro-
gen 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 Col-
umns (9A) and (9B) of the § 172.101 Haz-
ardous Materials Table must not be 
transported by air.
