Hazardous chemicals

Understand the danger, by degree.

Signal words on product labels help identify and compare the hazard potential of chemicals. DANGER is printed on a red background and identifies a high degree of hazard. WARNING is printed on an orange background and identifies a moderate degree of hazard. CAUTION is printed on a yellow background and identifies a reduced hazard.

USPS ensures employees get information on hazardous chemicals used in their work areas and that the information is communicated in a way they understand.

And that’s smart safety!
