The hazard of dangerous goods is indicated either by it’s class or it’s class and division. A large placard is used as an identifier on each side any container or vehicle being used for transport. A primary hazard class placard must have the hazard class or division number displayed in the lower corner of the placard. No hazard class or division number may be displayed on a placard representing the secondary hazard of a material. With the exception of Class 7 and the OXYGEN placard text indicating the hazard is not required.

Labels are used as identifiers on all small containers / packages being used to ship hazardous materials. They are smaller versions of placards with either the same or similar designs. Labels may have symbols which indicating the packing group or division rather than the class.

Shipping documents are required which give the details of the materials being shipped along with their hazard class or their hazard class and division number for each type of material in the shipment.
