Which item is not authorized in storage spaces?

• A. Bomb build-up
• B. Unpackaged munitions
• C. Spare tools
• D. Weathered crates

Answer: (A)

In munition storage, everything must be kept at approved quantities and in approved configurations to minimize risk. A bomb build-up represents an unsafe accumulation of explosive material in one area, which increases the chances of accidental initiation, makes fires harder to control, and can block access or hinder emergency response. That situation directly violates safety standards for storage spaces, so it is not allowed. Unpackaged munitions, spare tools, and weathered crates may be managed under specific rules and housekeeping practices, but none of these describe an unsafe buildup of energetic material like a bomb pile would. The key idea is that any accumulation beyond what’s authorized creates a higher, unacceptable level of risk.
