According to ICAO/IATA regulations, dangerous goods are defined as capable of causing a hazard to which aspects?

• A. Safety
• B. Property
• C. The environment
• D. All of the above

Answer: (D)

In ICAO/IATA terms, dangerous goods are substances or articles that, because of their chemical or physical properties, may pose hazards to health and safety, to property, or to the environment during air transport. The regulations are built to cover any risk that could affect people on board or on the ground, damage aircraft or infrastructure, or cause environmental harm. Because a single substance can threaten more than one area, the definition deliberately includes all three. That’s why choosing “All of the above” is correct.

Think of a toxic solvent: it can endanger people’s health (safety), potentially damage equipment or ignite hazards that threaten property, and if spilled, could contaminate water or soil and harm ecosystems. The rules require appropriate classification, packaging, labeling, and handling to address risks in all these facets.
