What type of safety device prevents accidental detonation of a munition?

The safety fuse is designed to prevent accidental detonation of a munition by providing a controlled, safe means of igniting the explosive charge only when intended. This device ensures that the munition can't be unintentionally activated through mechanical shock, temperature changes, or other unintended influences.

In contrast, a detonator is typically the device activated to initiate an explosion once the fuse is in place, while an initiator is often used to start a chain reaction in a munition system. The trigger mechanism, on the other hand, is part of the mechanism that allows for the intentional detonation of the munition at the correct time. Our focus on the safety fuse highlights its crucial role in ensuring the safety and reliability of munitions before they are deliberately detonated.
