Hazmat certification is required to be obtained by workers who remove, handle, or transport hazardous materials. This comprises careers in transportation and shipping, firefighting and emergency rescue, construction and mining, as well as waste treatment and disposal.

Certification involves having the knowledge of the risks and safety measures for handling these materials.
