What documentation accompanies shipments of dry ice materials?

The correct response is that shipments of dry ice materials are accompanied by DD Form 1502. This form is specifically used for the transportation of hazardous materials, including dry ice, which is considered a refrigerant under regulations concerning the transport of dangerous goods. DD Form 1502 provides essential information about the shipment, including the nature of the hazardous material, handling instructions, and the necessary precautions for safety during transport.

In this context, it’s important to understand that while other forms or labels may be necessary for certain types of shipments, DD Form 1502 is mandated for dry ice transport due to its classification. This ensures compliance with safety regulations and proper handling to mitigate any risks associated with the material.
