Which label denotes material that can be shipped for a limited time without refrigeration?

The designation of materials that can be shipped for a limited time without refrigeration is indicated by the DD Form 1502-2. This form is specifically utilized to communicate that the contents being shipped are perishable but can withstand certain environmental conditions for a specified duration. The labeling system in the DD Form series categorizes different types of shipments and their requirements, ensuring that personnel involved in logistics and transportation can manage and handle materials accordingly.

Understanding the differentiation between the forms is crucial. The other options, such as the DD Form 1502, 1502-1, and 1502-3, pertain to different specifications or conditions for material handling and shipping. For example, DD Form 1502 might not specifically denote limitations on refrigeration, while the other two have their respective usages unrelated to the time-sensitive non-refrigeration aspect. This organization helps maintain clarity in logistics processes and assists in the proper management of perishable goods within the Air Force supply chain.
