What AFI states that you will normally de-energize electrical circuits unless approved by the Base Civil Engineer?

The correct reference for the procedure of de-energizing electrical circuits is AFI 91-203. This Instruction provides guidelines on establishing safety rules and practices for personnel working around electrical systems. It emphasizes the importance of de-energizing circuits to ensure safety during maintenance or repair work unless there is explicit approval from the Base Civil Engineer to keep the circuits energized. This approach helps to minimize the risk of electrical shock, accidents, and injuries, which are critical concerns in electrical safety protocols.

Other references mentioned may provide important information regarding electrical safety and system management, but they do not specifically highlight the requirement to de-energize circuits nor do they set the same regulations. AFI 32-1064, for example, deals with the design and installation of electrical systems but does not address the de-energizing protocols in the manner that AFI 91-203 does. Understanding these distinctions is vital for adhering to proper electrical safety practices.
