Which organization regulates transportation safety for propane?

• A. Environmental Protection Agency (EPA).
• B. Department of Transportation (DOT).
• C. Food and Drug Administration (FDA).
• D. Occupational Safety and Health Administration (OSHA).

Answer: (B)

Transportation safety for propane is overseen by the Department of Transportation because propane is a hazardous material that must move under specific federal rules. The DOT, mainly through PHMSA, enforces the Hazardous Materials Regulations, which cover how propane is packaged, labeled, documented, and transported, plus driver training and routing rules for highway, rail, and water shipments. This ensures safe handling and minimizes risk during transit. The EPA focuses on environmental impacts, FDA on foods and drugs, and OSHA on workplace safety—none regulate the day-to-day safety of moving propane from one location to another.
