Why is static electricity a concern with munitions, and how is it mitigated?

• A. Static can ignite energetic material; mitigated by grounding and bonding equipment, anti-static garments, and keeping the work area dry.
• B. Static is beneficial for charging munitions.
• C. Static only causes minor shocks, no mitigation needed.
• D. Static is eliminated by increasing humidity alone.

Answer: (A)

Static electricity is a concern with munitions because a buildup of electrical charge can discharge as a spark, and that spark can ignite energetic material. To prevent that, the handling area is kept under control to allow charges to be removed safely. Grounding and bonding provide a continuous low-resistance path to earth, so any charge on equipment or personnel is carried away instead of flashing as a spark to a munition. Anti-static garments and footwear reduce the amount of charge generated by movement and handling, limiting how much charge gets introduced into the system. Keeping the work area dry minimizes moisture that could create unintended leakage paths or accelerate discharge through unpredictable routes, helping ensure any stray charges dissipate through the intended grounding system. Static shocks aren’t something to rely on, and humidity alone doesn’t eliminate static; proper grounding, bonding, and anti-static protection are essential.
