HAZARD CLASSIFICATION SYSTEM

The hazard class of dangerous goods is indicated either by its class (or division) number or name.
Placards are used to identify the class or division of a material. The hazard class or division number
must be displayed in the lower corner of a placard and is required for both primary and subsidiary
hazard classes and divisions, if applicable. For other than Class 7 or the OXYGEN placard, text
indicating a hazard (for example, “CORROSIVE”) is not required. Text is shown only in the U.S. The
hazard class or division number and subsidiary hazard classes or division numbers placed in
parentheses (when applicable), must appear on the shipping document after each proper shipping
name.
