LABELING HAZARDOUS MATERIALS
A15.1. General Requirements. Unless otherwise specified in this manual, apply the appropriate labels to the outside container
of packages containing hazardous materials.
Use labels meeting the commercial color and specifications outlined in 49 CFR 172.411 through 172.450, ICAO
Technical Instructions or IATA Dangerous Goods Regulation. Do not use labels that are easily confused by their use,
shape, and color, with the standard labels prescribed.
Labels must be diamond-shaped with each side at least 10 cm (4 inches) long and have a solid line border 6.3 mm (0.25
inches) from the edge.
The hazard class and division number must be at least 6.3 mm (0.25 inches) and not greater than 12.7 mm (0.5 inches).
The label text must be at least 7.6 mm (0.3 inches) and will be in capitalized Roman letters.
It is the shipping activitys responsibility to establish procedures to locally fund for and procure hazardous material labels
and commercial forms.
Secondary hazards do not require labels.
A15.2. Hazard Labels.
Place on the outer packaging a primary hazard label and a subsidiary risk label based on the hazard
classification/subsidiary risk provided in columns 3 and 6 of table A4.1. Include the hazard class or division number in
the bottom corner of the label(s). Labels that do not have the class or division number preprinted may be stamped or
overprinted with the appropriate hazard class/division number in the bottom corner of the label.
For explosives, include the division number and compatibility group letter. Ensure the compatibility group letter
is a capitalized Roman letter.
For Division 5.1 oxidizers and Division 5.2 organic peroxides, include the division number in the bottom corner
of the label.
Attach labels to the part of the package bearing the PSN if package size is adequate.
Do not place labels over any identifying data on the container. Remove or obliterate any irrelevant labeling already on
When hazardous materials having different classes are packed in the same packaging or outside container, the outside
container must be labeled as required for each material (including subsidiary risks). If the primary hazard or subsidiary
risk label of another component already adequately identifies a primary or subsidiary risk, it is not required to repeat this
warning by applying another label.
When hazardous materials are palletized on a 463L or warehouse pallet, ensure the label is clearly visible.
Position hazardous cargo loaded in the back of a vehicle so the labels are clearly visible, or apply the labels for each
hazard loaded in the back of the vehicle to a marker board that is clearly visible.
Label each Limited Quantity package for each dangerous good contained in the package.
Excepted Quantities container only requires a completed "Dangerous Goods in Excepted Quantities" label attached to the
Label hazardous waste with the appropriate hazard label and properly completed hazardous waste label.
For items shipped under the PSN Dangerous Goods in Machinery or Dangerous Goods in Apparatus apply primary
and subsidiary risk hazard labels for each hazard contained therein on the machinery, apparatus, or packaging (unless
exempted by A15.4.6). Apply Package Orientation (This Way Up) labels to opposite vertical sides when required to
ensure liquid hazardous materials remain in their intended orientation.
Do not apply hazard labels to a package containing material that is not regulated.
