In addition to any other markings re-

quired by this subpart:

be marked ‘‘Inhalation Hazard’’ in as-
sociation with the required labels or 
placards, as appropriate, and shipping 
name when required. The marking 
must be on two opposing sides of a bulk 
packaging. (See § 172.302(b) of this sub-

ard’’ appear on the label, as prescribed 
in §§ 172.416 and 172.429, or placard, as

quired on the package. 

(b) Each non-bulk plastic outer pack-

aging used as a single or composite 
packaging for materials meeting the 
definition of Division 6.1 (in § 173.132 of 
this subchapter) shall be permanently 
marked, by embossment or other dura-
ble means, with the word ‘‘POISON’’ in 
letters at least 6.3 mm (0.25 inch) in 
height. Additional text or symbols re-
lated to hazard warning may be in-
cluded in the marking. The marking 
shall be located within 150 mm (6 
inches) of the closure of the packaging. 

(c) A transport vehicle or freight con-

tainer containing a material poisonous 
by inhalation in non-bulk packages 
shall be marked, on each side and each 
end as specified in § 172.332 or § 172.336, 
with the identification number speci-
fied for the hazardous material in the 
§ 172.101 table, subject to the following 
provisions and limitations: 

(1) The material is in Hazard Zone A 

or B; 

(2) The transport vehicle or freight 

container is loaded at one facility with 
1,000 kg (2,205 pounds) or more aggre-
gate gross weight of the material in 
non-bulk packages marked with the 

same proper shipping name and identi-
fication number; and 

(3) If the transport vehicle or freight 

container contains more than one ma-
terial meeting the provisions of this 
paragraph (c), it shall be marked with 
the identification number for one ma-
terial, determined as follows: 

(i) For different materials in the 

same hazard zone, with the identifica-
tion number of the material having the 
greatest aggregate gross weight; and 

(ii) For different materials in both 

Hazard Zones A and B, with the identi-
fication number for the Hazard Zone A 
material.

vision 6.1 PG III material, ‘‘PG III’’

SON label. (See § 172.405(c).)

tity requirements in part 173 of this
