The operator must retain a copy of which document at ground level until the shipment has reached its destination?

• A. Dangerous Goods Manifest
• B. Air Waybill
• C. Shipper's Declaration
• D. Packing List

Answer: (C)

The key idea is understanding which document proves that dangerous goods have been properly declared and handled. The Shipper's Declaration is the formal certificate completed by the shipper stating that the dangerous goods are properly classified, packaged, labeled, and documented in compliance with all applicable regulations. Because it documents compliance and safety details, the operator must keep a copy at ground level for the entire journey, so it’s available for regulatory checks and in case of any incident or audit until the shipment reaches its destination. Other documents serve different roles (the transport contract, packing details, or flight manifests) and are not the specific declaration that establishes regulatory compliance which the operator must retain at the ground.
