Which items are typically incompatible to store together?

Which items are typically incompatible to store together?

• A. Plastic and metal components.
• B. Items produced in the same month.
• C. Detonators/initiators with primary explosives; oxidizers with fuels; incompatible packaging or moisture conditions that could precipitate degradation.
• D. Ammunition of different calibers.

Answer: (C)

In storage safety, the guiding rule is to keep reactive or sensitive materials apart to prevent any accidental interaction. Detonators and initiators are highly sensitive starting devices, and pairing them with primary explosives dramatically raises the risk that a minor impact, heat, or friction could trigger a detonation. Oxidizers and fuels represent another dangerous pairing: if they come into contact, they can react exothermically and violently, potentially causing ignition or an explosion. Moisture conditions and degraded packaging can also drive hazards by weakening seals, promoting corrosion, or altering the stability of materials, which is why proper packaging integrity and moisture control are emphasized in storage practices. Together, these factors illustrate why these particular items are stored separately with barriers or distance to maintain safe storage. Other choices don’t reflect inherent incompatibilities in the same way. Plastic and metal components can often be stored together without issue, depending on their materials and packaging. Production date has no bearing on chemical compatibility, and ammunition of different calibers can generally be stored together if handled and organized correctly, though other handling considerations may apply.
