§ 172.403

Class 7 (radioactive) mate-

rial. 

(a) Unless excepted from labeling by 

§§ 173.421 through 173.427 of this sub-
chapter, each package of radioactive 
material must be labeled as provided in 
this section. 

(b) The proper label to affix to a 

package of Class 7 (radioactive) mate-
rial is based on the radiation level at 
the surface of the package and the 
transport index. The proper category of 
label must be determined in accord-
ance with paragraph (c) of this section. 
The label to be applied must be the 
highest category required for any of 
the two determining conditions for the 
package. RADIOACTIVE WHITE-I is 
the lowest category and RADIO-
ACTIVE YELLOW-III is the highest. 
For example, a package with a trans-
port index of 0.8 and a maximum sur-
face radiation level of 0.6 millisievert 
(60 millirems) per hour must bear a 
RADIOACTIVE YELLOW-III label. 

(c) Category of label to be applied to 

Class 7 (radioactive) materials pack-

(d) 

EMPTY label. See § 173.428(e) of 

this subchapter for EMPTY labeling re-
quirements. 

(e) 

FISSILE label. For packages re-

quired in § 172.402 to bear a FISSILE 
label, each such label must be com-
pleted with the criticality safety index 
(CSI) assigned in the NRC or DOE 
package design approval, or in the cer-
tificate of approval for special arrange-
ment or the certificate of approval for 
the package design issued by the Com-
petent Authority for import and export 
shipments. For overpacks and freight 
containers required in § 172.402 to bear 
a FISSILE label, the CSI on the label 
must be the sum of the CSIs for all of 
the packages contained in the over-
pack or freight container. 

(f) Each package required by this sec-

tion to be labeled with a RADIO-
ACTIVE label must have two of these 
labels, affixed to opposite sides of the 
package. (See § 172.406(e)(3) for freight 
container label requirements). 

(g) The following applicable items of 

information must be entered in the 
blank spaces on the RADIOACTIVE 
label by legible printing (manual or 
mechanical), using a durable weather 
resistant means of marking: 

(1) 

Contents.  Except for LSA-1 mate-

rial, the names of the radionuclides as 
taken from the listing of radionuclides 
in § 173.435 of this subchapter (symbols 
which conform to established radiation 
protection terminology are authorized, 
i.e.

99

Mo, 

60

Co, etc.). For mixtures of 

radionuclides, with consideration of 
space available on the label, the radio-
nuclides that must be shown must be 
determined in accordance with 
§ 173.433(g) of this subchapter. For LSA- 
I material, the term ‘‘LSA-I’’ may be 

used in place of the names of the radio-
nuclides. 

(2) 

Activity. The maximum activity of 

the radioactive contents in the pack-
age during transport must be expressed 
in appropriate SI units (

e.g., Becquerels 

(Bq), Terabecquerels (TBq)). The activ-
ity may also be stated in appropriate 
customary units (

e.g.,  Curies (Ci), 

milliCuries (mCi), microCuries (uCi)) 
in parentheses following the SI units. 
Abbreviations are authorized. Except 
for plutonium-239 and plutonium-241, 
the weight in grams or kilograms of 
fissile radionuclides (or the mass of 
each fissile nuclide for mixtures when 
appropriate) may be inserted instead of 
activity units. For plutonium-239 and 
plutonium-241, the weight in grams of 
fissile radionuclides (or the mass of 
each fissile nuclide for mixtures when 
appropriate) may be inserted in addi-
tion to the activity units. 

(3) 

Transport index. (see § 173.403 of 

this subchapter.) 

(h) When one or more packages of 

Class 7 (radioactive) material are 
placed within an overpack, the over-
pack must be labeled as prescribed in 
this section, except as follows: 

(1) The ‘‘contents’’ entry on the label 

may state ‘‘mixed’’ in place of the 
names of the radionuclides unless each 
inside package contains the same 
radionuclide(s). 

(2) The ‘‘activity’’ entry on the label 

must be determined by adding together 
the number of becquerels of the Class 7 
(radioactive) materials packages con-
tained therein. 

(3) For an overpack, the transport 

index (TI) must be determined by add-
ing together the transport indices of 
the Class 7 (radioactive) materials

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.

§ 172.405

Authorized label modifica-

tions. 

(a) For Classes 1, 2, 3, 4, 5, 6, and 8, 

text indicating a hazard (for example 
FLAMMABLE LIQUID) is not required 
on a primary or subsidiary label. 

(b) For a package containing Oxygen, 

compressed, or Oxygen, refrigerated 
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
