Which guidance governs grounding systems?

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

Answer: (D)

Grounding systems in Air Force facilities are governed by the Air Force Instruction that specifically covers electrical grounding and bonding. This instruction lays out the design, installation, testing, and maintenance requirements for grounding systems, including electrode arrangements, conductor sizing, and bonding of all metallic parts. It’s the direct, official guide used to ensure consistency, safety, and mission readiness across Air Force installations. General references like NFPA 70 provide the broader electrical code framework, and OSHA 1910 covers workplace electrical safety, but they do not constitute the Air Force’s specific governing document for grounding. DoD 4145-related policies exist at a higher DoD level, but for Air Force facilities the AFI directs the grounding and bonding practices.
