Which statement about the requirements around dangerous goods training is true?

The statement that all personnel involved must be fully trained reflects the comprehensive nature of regulations surrounding dangerous goods (DG) training. Under various regulations, such as those set by the International Air Transport Association (IATA) and the US Department of Transportation (DOT), it is mandatory for anyone who handles, prepares, or transports dangerous goods to receive proper training. This ensures that all individuals involved in the supply chain, including shippers, freight forwarders, ground handlers, and carriers, understand how to recognize, handle, and respond appropriately to dangerous goods, thereby enhancing safety and compliance.

Training is not limited to any one subset of personnel—including only forwarders or carriers—because the risk associated with dangerous goods can arise at any point in the transport process. Additionally, the weight of the cargo does not exempt anyone from needing training; all involved must be aware of the hazards, regardless of the quantity being transported. The approach ensures a holistic understanding and preparedness among all roles to minimize risks associated with dangerous goods transportation.
