What is one requirement for controlling ammunition and explosives locks and keys?

One important requirement for controlling ammunition and explosives locks and keys is the necessity to replace a lost key immediately. This is critical for maintaining security and safety protocols in handling ammunition and explosives. If a key is lost, it raises the potential for unauthorized access, which could lead to dangerous situations or security breaches. Promptly replacing the lost key ensures that all locks remain secure and that the integrity of the storage is maintained.

In the context of maintaining controls, not addressing a lost key could compromise the safety measures in place. This requirement emphasizes vigilance and proactive measures in managing access to sensitive materials. Ensuring that all keys are accounted for and replacing any that go missing is a fundamental aspect of responsible ammunition handling practices.
