IATA Hazard Labels

All hazard labels must be in the form of a square, with minimum dimensions of 100 x 100 mm, set at a 45° angle (diamond shaped). Each label has a 5 mm line running along the inside edge. In the upper half, the line must be the same color as the symbol, and in the lower half the line must be the same color as the figure in the bottom corner.

With the exception of Divisions 1.4, 1.5, and 1.6, hazard labels are divided in half. The upper half contains the pictorial symbol, and the lower half contains text, including the class or division number and the compatibility group letter, as appropriate. The symbols, text, and numbers must be shown in black, with the following exceptions:

• Class 8 label, where the text, if any, and class number must appear in white
• Labels with entirely green, red, or blue backgrounds may have white text
• Division 5.2, where the symbol may be shown in white

The DGR recommends using the Pantone® Formula Guide to achieve proper color requirements.

Text indicating the nature of the risk may be included in the lower half of the label in addition to the class, division number, or compatibility group. The text should be in English, unless otherwise required by the State of origin. If another language is used, the English translation must be provided.

A primary hazard label is specified for each listed article and substance, and a secondary hazard label or labels must also be applied for any subsidiary risks. The labels identifying the primary and subsidiary hazards must bear the class or division number, as required.

Salvage packagings must be labeled with all appropriate labels for the dangerous goods contained within the packaging, as well as a "Cargo Aircraft Only," if required.

Empty packaging that previously contained dangerous goods must be labeled as if it still contained the dangerous goods, unless it has been properly cleaned, purged of vapors, and refilled with non-dangerous goods to nullify any hazard.

If two or more dangerous goods are packed in the same outer packaging, the package must be labeled as required for each dangerous good substance. Only one hazard label is required for each class or division contained within the package.
