What are dangerous goods?

• A. A type of nonhazardous cargo.
• B. The aviation term for hazardous materials; hazmat incidents may initially appear as medical aid, fire, vehicle accident, or aircraft accident.
• C. Only flammable liquids.
• D. Only explosive materials.

Answer: (B)

Dangerous goods are substances or items that pose hazards to people, property, or the environment during transport due to factors like flammability, toxicity, reactivity, corrosivity, or radioactivity. In aviation, this is called hazmat—hazardous materials—and there are specific rules for how they are packed, labeled, and handled on aircraft. The correct choice captures this aviation term and notes that hazmat incidents can show up as medical aid scenes, fires, vehicle accidents, or aircraft accidents because dangerous goods can be involved in many different types of emergencies. Remember, dangerous goods aren’t limited to flammable liquids or explosives; they cover a wide range of hazards, including toxic substances, corrosives, oxidizers, compressed gases, and batteries. For responders, recognizing hazmat guides protective measures, scene control, decontamination, and coordination with hazmat specialists.
