Maintaining proper temperature and humidity is about preserving the chemical and physical integrity of ammunition so it stays safe and reliable over time. Heat accelerates chemical reactions in propellants and primers, which can lead to degraded performance or unsafe pressure when fired. Humidity allows moisture to penetrate casings and metal components, promoting corrosion and moisture-related damage that can weaken parts, foul primers, or affect seals. Keeping conditions stable and moderate slows both degradation and corrosion, helping to preserve shelf life and reliability. The other options don’t address the factors that affect stability and safety—environmental controls won’t maximize explosive power, influence lighting, or directly reduce theft risk.
