Which term is used for international transport of hazardous materials?

• A. Dangerous Goods
• B. Hazardous Materials
• C. OSHA HAZWOPER
• D. NFPA 1991

Answer: (A)

Dangerous goods is the term used for international transport because the global system built by the United Nations, and adopted by IATA, ICAO, IMDG, and ADR, labels substances that pose hazards during movement across borders as dangerous goods. This terminology spans air, sea, road, and rail, providing a universal language for shipping hazardous materials worldwide. In domestic US contexts, the same materials are often referred to as hazardous materials under 49 CFR, but that is a domestic labeling convention rather than the international standard. OSHA HAZWOPER relates to hazardous materials operations and emergency response regulations, not transport terminology, and NFPA 1991 addresses protective ensembles rather than how materials are classified for transport. So the international label you’d encounter across all modes of transport is dangerous goods.
