49 CFR Ch. I (10–1–18 Edition) 

§ 172.404 

packages contained therein, except 
that for a rigid overpack, the transport 
index (TI) may alternatively be deter-
mined by direct measurement as pre-
scribed in § 173.403 of this subchapter 
under the definition for ‘‘transport 
index,’’ taken by the person initially 
offering the packages contained within 
the overpack for shipment. 

(4) The category of Class 7 label for 

the overpack must be determined from 
the table in § 172.403(c) using the TI de-
rived according to paragraph (h)(3) of 
this section, and the maximum radi-
ation level on the surface of the over-
pack. 

(5) The category of the Class 7 label 

of the overpack, and not that of any of 
the packages contained therein, must 
be used in accordance with Table 1 of 
§ 172.504(e) to determine when the 
transport vehicle must be placarded. 

(6) For fissile material, the criti-

cality safety index which must be en-
tered on the overpack FISSILE label is 
the sum of the criticality safety indi-
ces of the individual packages in the 
overpack, as stated in the certificate of 
approval for the package design issued 
by the NRC or the U.S. Competent Au-
thority.

§ 172.404

Labels for mixed and consoli-

dated packaging. 

(a) 

Mixed packaging. 

When compatible 

hazardous materials having different 
hazard classes are packed within the 
same packaging, or within the same 
outside container or overpack as de-
scribed in § 173.25, the packaging, out-
side container or overpack must be la-
beled as required for each class of haz-
ardous material contained therein. 

(b) 

Consolidated packaging. 

When two 

or more packages containing compat-
ible hazardous materials are placed 
within the same outside container or 
overpack, the outside container or 
overpack must be labeled as required 
for each class of hazardous material 
contained therein, unless labels rep-
resentative of each hazardous material 

in the outside container or overpack 
are visible. 

(c) 

Consolidation bins used by a single 

motor carrier. 

Notwithstanding the pro-

visions of paragraph (b) of this section, 
labeling of a consolidation bin is not 
required under the following condi-
tions: 

(1) The consolidation bin must be re-

usable, made of materials such as plas-
tic, wood, or metal and must have a ca-
pacity of 64 cubic feet or less; 

(2) Hazardous material packages 

placed in the consolidation bin must be 
properly labeled in accordance with 
this subpart; 

(3) Packages must be compatible as 

specified in § 177.848 of this subchapter; 

(4) Packages may only be placed 

within the consolidation bin and the 
bin be loaded on a motor vehicle by an 
employee of a single motor carrier; 

(5) Packages must be secured within 

the consolidation bin by other pack-
ages or by other suitable means in such 
a manner as to prevent shifting of, or 
significant relative motion between, 
the packages that would likely com-
promise the integrity of any package; 

(6) The consolidation bin must be 

clearly and legibly marked on a tag or 
fixed display device with an indication 
of each hazard class or division con-
tained within the bin; 

(7) The consolidation bin must be 

properly blocked and braced within the 
transport vehicle; and 

(8) Consolidation bins may only be 

transported by a single motor carrier, 
or on railcars transporting such vehi-
cles.

(b) For a package containing Oxygen,

liquid, the OXIDIZER label specified in 
§ 172.426 of this subpart, modified to dis-
play the word ‘‘OXYGEN’’ instead of 
‘‘OXIDIZER’’, and the class number 
‘‘2’’ instead of ‘‘5.1’’, may be used in 
place of the NON-FLAMMABLE GAS 
and OXIDIZER labels. Notwithstanding 
the provisions of paragraph (a) of this
