Final answer:
Crew members must know about Dangerous Goods Regulations to ensure the recognition and safe handling of dangerous goods, make informed decisions about passenger safety, and support ground personnel properly.
Step-by-step explanation:
It is necessary for crew members to have knowledge about Dangerous Goods Regulations (DGR) for several reasons:
- To recognize and handle dangerous goods when found on the aircraft, ensuring the safety of the flight.
- To be aware of the regulations regarding the transportation of such goods, which allows them to make informed decisions about passenger safety when dangerous goods are found in someone's possession.
- To provide essential support to ground personnel, who must handle DGR-compliant items according to established procedures.
Proper training in DGR ensures that the crew can respond effectively to potential emergencies involving dangerous goods, maintain regulatory compliance, and uphold passenger and aircraft safety.
