Which of the following statements is true regarding air shipments of dangerous goods?

The statement that all dangerous goods must be packed according to specific regulations is true and reflects the stringent safety protocols in place for air transport. Dangerous goods, which can include solids, liquids, and gases, are materials that pose risks to health, safety, property, or the environment during transportation. Therefore, they must be packaged, labeled, and documented in accordance with regulations such as those established by the International Air Transport Association (IATA) and other governing bodies.

The requirement for compliance with specific regulations is crucial because improper handling and packing of these goods can lead to serious safety hazards during air transport. These regulations dictate how substances should be classified, labeled, and handled, ensuring that all necessary precautions are taken to mitigate any risks associated with air shipments of dangerous materials.

This focus on regulation also distinguishes it from options suggesting that transportation is less regulated than other modes or that no regulations apply at all, which is not the case. Proper training and adherence to guidelines are essential for anyone involved in shipping dangerous goods by air.
