Excessive heat triggers chemical and material changes in munitions that threaten safety and reliability. Propellants can thermally decompose when overheated, producing gases and increasing internal pressure, which can distort or rupture the casing and push the fuze timing off. Fuzes are temperature-sensitive and may become unreliable or detonate unpredictably when exposed to heat. Seals and gaskets can soften or degrade, leading to leaks or compromised containment. Because of these risks, heat can degrade casings, propellants, or fuzes, making temperature control and proper storage essential. The other options misstate the effects, as heat does not strengthen seals, nor does proper storage eliminate heat risks, and it certainly doesn’t lessen the need for temperature control.
