The agency historically used to cover 9 classes of hazardous materials is which?

• A. OSHA
• B. DOT used to cover 9 classes
• C. EPA
• D. UN model codes and regulations

Answer: (B)

In the U.S., the system of nine hazard classes used for transporting hazardous materials was established by the Department of Transportation. The DOT’s Hazardous Materials Regulations group hazmats into nine classes: Explosives; Gases; Flammable liquids; Flammable solids; Oxidizers and organic peroxides; Toxic substances and infectious substances; Radioactive materials; Corrosives; and Miscellaneous dangerous goods. This framework guides packaging, labeling, and shipping requirements across highway, rail, air, and water. OSHA focuses on workplace safety, not the transport classification; the EPA handles environmental protection; and UN model regulations provide international guidelines, not a U.S. agency.
