Which of these regulatory guidance documents governs explosive safety standards?

The correct regulatory guidance document that governs explosive safety standards is indeed the document referenced in the correct answer. This specific publication, DESR 6055.09_AFMAN 91-201, covers the Department of Defense's standards regarding explosive safety with a focus on the protection of personnel, property, and the environment from explosive hazards. It outlines procedures for the safe handling, storage, transportation, and use of explosives, ensuring compliance with safety protocols.

The importance of this document cannot be overstated, as it embodies critical safety regulations that all personnel involved in handling explosives must adhere to. By establishing a comprehensive set of guidelines, it helps mitigate risks associated with explosives, thereby enhancing overall safety and accountability in explosive operations.

Other options, while relevant to safety and operational standards, are not specifically dedicated to explosive safety. Each document has its particular focus, such as broader safety management, weapon system safety, or industrial safety standards, which do not directly address the regulations governing explosive safety in the same detailed manner.
