Which agency regulates labels and placards for transporting hazardous materials?

• A. OSHA
• B. EPA
• C. NFPA
• D. U.S. DOT

Answer: (D)

Labeling and placarding for transporting hazardous materials are regulated by the U.S. Department of Transportation. This agency, through the Pipeline and Hazardous Materials Safety Administration, sets the Hazardous Materials Regulations that specify which labels and placards must appear, how they are displayed, and where they are used on packages and transport vehicles to communicate hazards to handlers and emergency responders. The other agencies don’t control transport labeling: OSHA handles workplace chemical labeling and safety standards, the EPA focuses on environmental protection, and NFPA provides on-site safety standards (like NFPA 704) for fixed facilities rather than transportation.
