It addresses lightning-safe configurations, side flash separation distances, and operations in hardened or protective aircraft shelters. It requires approved deviations from paragraph 5.10 and specifies when seven-foot separation applies.
Applies to: This instruction applies to all civilian employees and uniformed members of AFGSC Regular Air Force, Air Force Reserve, and Air National Guard.
Weapon specific technical orders may apply additional lightning safe configurations for weapon and /or personnel safety.
The required side flash separation distance is properly applied to a nuclear weapon (or STMS) when an unobstructed minimum seven-foot clear zone exists between the weapon (or STMS) and the facility’s walls, ceiling, or any other structural member capable of conducting electrical energy (e.g., steel columns, rebar-reinforced interior walls, columns or beams).
Objects in the floor such as concrete rebar, floor grounds, and structural members of the Weapon Storage Vault, when the vault is in a full down position, do not require the application of the side flash separation distance.
Transient or temporary infringement of the side flash separation distance requirement can be permitted.
