Which statement about lightning protection systems (LPS) for ammo storage is correct?

• A. Only outdoor ammo areas require LPS
• B. LPS is optional
• C. LPS is only for high-risk facilities
• D. All areas storing ammo require a lightning protection system (LPS)

Answer: (D)

Lightning protection for ammo storage focuses on preventing ignition by diverting lightning energy safely to ground. The risk from a direct strike or a surge can affect any area where ammunition is kept, not just outdoor spaces or only the most exposed facilities. A properly designed system provides a clear, low-impedance path for lightning energy, limits voltage differences between structures and equipment, and reduces the chance of sparks, heat, or arcing reaching stored primers or propellants. Because every area that stores ammunition could be irradiated by a lightning event or a surge entering through power or communication lines, protection should be applied across the entire storage site. That's why the correct approach is that all areas storing ammo require a lightning protection system. Limiting protection to outdoor areas, to only high-risk facilities, or deeming it optional would leave potential ignition paths unprotected.
