What safety device is often employed to secure explosive materials?

Safety pins or clips are commonly employed to secure explosive materials because they provide a reliable mechanism for preventing inadvertent functioning or ignition of explosive devices. These devices act as a physical barrier, ensuring that the explosive component remains inactive until it is intentionally removed by a qualified individual. This is particularly important in managing the risk associated with handling, transporting, or storing explosives.

For instance, when working with grenades or other munitions, safety pins or clips are designed to hold the firing mechanism in a safe position until the device is ready for deployment. Once the pin is removed, it allows the device to function as intended. The simplicity and effectiveness of this method make it a standard safety procedure in explosive ordnance disposal and other explosive handling scenarios.

Other options, while they may have security applications in various contexts, do not provide the same level of direct safety and immediate functionality in securing explosive materials.
