What type of hand tools do Gunner's Mates (GMs) use when working around explosives?

Gunner's Mates (GMs) use nonferrous tools when working around explosives primarily to minimize the risk of sparking or creating a reaction with the explosive materials. Nonferrous tools, which are made from materials that do not contain iron, such as aluminum, brass, or plastic, are essential in explosive handling because they are less likely to cause sparks upon impact with other surfaces.

The use of nonferrous materials is crucial in ensuring safety when working with sensitive materials, as even a small spark can lead to dangerous outcomes. In contrast, tools made from ferrous materials (which contain iron) can rust, corrode, and pose a higher risk in explosive environments due to their magnetic properties and tendency to spark if struck against other hard surfaces. This is a critical safety consideration in preventing accidents during the handling and maintenance of munitions and related equipment.
