In aviation, the term dangerous goods refers to what?

• A. Hazardous materials.
• B. Nonhazardous materials.
• C. Perishable items.
• D. Domestic freight.

Answer: (A)

Dangerous goods in aviation are materials that can pose hazards to people, aircraft, or the environment during transport because of properties like flammability, toxicity, corrosivity, or radioactivity. They are hazardous materials that must be properly classified, packaged, labeled, documented, and handled under international rules (like the IATA Dangerous Goods Regulations and ICAO Technical Instructions). Nonhazardous materials, perishable items, and domestic freight don’t carry inherent danger in the transport sense, so they aren’t defined as dangerous goods. Understanding this distinction helps ensure proper containment, stowage, and emergency response planning for any item that could pose a risk.
