What risk arises from ignoring compatibility groups and segregation?

• A. Improved storage efficiency but no safety risk.
• B. No risk; it's only a guideline.
• C. Unintended initiation or sympathetic reactions between incompatible munitions.
• D. Better temperature control.

Answer: (C)

The main idea is that different munitions have varying sensitivities and chemical compatibility. When incompatible items are stored together, a triggering event—like heat, friction, or shock from one munition—can transfer energy or cause a reaction in another. This can lead to unintended initiation or sympathetic reactions, where one item detonates and sets off others. That cascading danger is exactly why segregation by compatibility groups matters. The other options misstate the risk: there is a safety risk, it’s not just a guideline, and it’s not primarily about temperature control.
