What is the term for hazardous materials under the UN model?

• A. Dangerous goods
• B. Hazardous substances
• C. Toxic items
• D. Regulated materials

Answer: (A)

In international transport rules, hazardous materials are referred to as dangerous goods. This is the standard term defined in the UN Recommendations on the Transport of Dangerous Goods Model Regulations and used across global systems (air, sea, road, and rail) to classify and handle materials that pose risks during shipping. The term covers a wide range of hazards—flammability, explosiveness, corrosivity, toxicity, radioactivity—not just toxicity. Hazardous substances is a general phrase for any substance with hazards, but it isn’t the formal UN model term for transport. Toxic items focus only on toxicity and miss other hazard types. Regulated materials is a broad regulatory label used in different contexts and doesn’t pinpoint the UN model’s specific transport terminology.
