Why is bonding and grounding required for metal containers and equipment in ammunition storage?

• A. To prevent static electricity from igniting sensitive materials.
• B. To meet unrelated building codes.
• C. To improve heating efficiency.
• D. To allow easier removal of containers.

Answer: (A)

Bonding and grounding metal containers and equipment in ammunition storage is about controlling static electricity. Handling and moving metal parts can generate an electrostatic charge, and energetic materials like propellants can ignite from a spark even at low energy. When all metal items are bonded to a common conductor, they share the same electrical potential; grounding ties that network to the earth so any charge can safely dissipate. This prevents voltage differences between containers, racks, and other metalwork, reducing the chance of an arc or spark during handling or transfer. The other options aren’t the purpose here—bonding and grounding aren’t about meeting unrelated building codes, heating efficiency, or making removal easier. Their safety value is specifically lowering ignition risk from static discharge in environments with energetic materials.
