It contains requirements for applying side flash separation distances around nuclear weapons, STMS, and facilities. It also specifies conditions for temporary infringements, reduced distances, and approved deviations.
Applies to: This publication applies to all AFMC units.
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.
Deviations from paragraph 5.10 must be approved by AFSEC/SEW.
