Which publication should be used to mark a package containing blasting caps?

The correct publication for marking a package containing blasting caps is MIL-STD-129R. This standard provides specifications for the identification marking of military supplies and equipment, and it includes requirements relevant to packaging and marking items that pose safety hazards, such as explosives and blasting caps. Proper marking is essential for ensuring safety during storage, handling, and transport, as it informs personnel of the contents and potential dangers associated with the materials.

Other options, while important in their respective contexts, do not specifically address the marking requirements for blasting caps. Understanding the specific regulations helps ensure compliance with safety standards and minimizes risks associated with the handling and storage of explosive materials.
