A substance or material in railcars or containers in railcars for transportation that the Secretary of Transportation has determined to pose an unreasonable risk to health, safety, and property when transported in commerce is called what?

• A. Hazardous Material (Hazmat)
• B. Hazardous Substance
• C. Dangerous Goods
• D. Hazardous Cargo

Answer: (A)

The idea being tested is how safety classifications for freight are defined in transportation law. When a substance or material in railcars or their containers is found to pose an unreasonable risk to health, safety, and property during transport in commerce, the Secretary of Transportation designates it as a hazardous material, or Hazmat. This is the standard term used in the Hazardous Materials Regulations (HMR) to identify items that require specialized handling, packaging, labeling, shipping papers, placards, and training because of their potential dangers in transit. Other terms pop up in different contexts—hazardous substance relates to environmental cleanup rules, dangerous goods is the international terminology used in some regimes, and hazardous cargo isn’t the formal DOT term—so Hazmat is the specific, correct designation for rail transport within U.S. regulations.
