Labels

Labels are approximately 4-inch diamond-shaped stickers applied to individual hazardous materials packages.

There are more labels specific to hazards than there are placards, i.e. radioactive labels and infectious substances labels. According to 49 C.F.R., most hazardous materials packages that are to be transported must be labeled.

Each label should be printed in the appropriate color. The labels should be durable and withstand exposure to transportation conditions.
Labels may be affixed to packages when not required by regulations provided each label presents a hazard of the material contained in the package.
The appropriate hazard class or division must be displayed in the lower corner of a primary and subsidiary hazard label.

Eight rolls of hazardous materials labels, one green placard with a cylinder, next to a red placard with a white flame on top, below that a blue placard with a white flame on top, next to a yellow placard with a black flame on top, with a white placard with a black and white striped top half. Below that, another black and white striped placard label, a red label with a white flame, next to a half black and a half white placard with a cylinder spilling liquid onto a hand and a flat surface.
