Which document should be consulted to verify proper grounding practices on a site?

• A. NFPA 70
• B. OSHA 1910
• C. DoD 4145
• D. AFI 32-1065

Answer: (D)

Grounding practices in an explosives environment are governed by the service’s own electrical safety rules, not just general electrical codes. In the Air Force, AFI 32-1065 lays out the specific requirements for electrical safety, including how grounding and bonding must be done on installations that handle munitions. It details how to design and maintain a proper grounding electrode system, how to bond equipment and structures, how to test continuity, and how to keep the system in safe, up-to-date condition to prevent static buildup or stray currents from causing ignition. Civilian standards like NFPA 70 or OSHA 1910 provide broad safety guidance, but they do not tailor to the explosive safety context or Air Force procedures, and DoD 4145 covers different procedural areas. Therefore, AFI 32-1065 is the document to consult for proper grounding practices on a site.
