Which practice best supports preventing chemical or physical reactions between munitions?

• A. Storing all munitions together regardless of hazard.
• B. Storing only heavy items at the bottom shelves.
• C. Maintain segregation of incompatible items.
• D. Using the same storage bin for all items.

Answer: (C)

Segregation of incompatible items prevents chemical or physical reactions between munitions by keeping materials with different chemical natures apart. Different munition types—oxidizers, fuels, reactive metals, pyrotechnics, and other energetic components—can interact violently if stored too close, especially under heat, moisture, or friction. By assigning storage areas or bins to specific hazard classes and maintaining physical separation between items that could react, you limit contact, reduce cross-contamination, and minimize the chance of an initiating event spreading from one item to another. This approach directly reduces the risk of unintended reactions and aligns with safe storage practices for munitions. Storing all items together, placing heavy items at the bottom, or using the same bin for everything does not address chemical compatibility and can increase the likelihood of a hazardous interaction.
