Which type of electrical equipment should be avoided in ammunition storage areas?

In ammunition storage areas, it is crucial to ensure that all electrical equipment is suitable for the potentially hazardous conditions present due to explosive materials. Standard electrical equipment that is not rated for explosive environments poses a significant risk because it may not have the necessary safeguards to prevent sparks or overheating, which could lead to ignition of explosive substances.

Choosing equipment specifically designed and rated for explosive environments (such as explosion-proof or intrinsically safe devices) helps ensure that any electrical activity does not compromise safety. These specially designed devices are built to contain any potential ignition sources, thereby minimizing the risk of accidents.

Battery-operated devices can be safe if they are used appropriately and don't generate sparks or heat that could ignite corrosive materials, while heavy-duty extension cords, when rated for use in hazardous locations, may also be acceptable. Hence, the safest approach in ammunition storage areas is to avoid equipment that does not meet explosive environment ratings, making standard electrical equipment an inappropriate choice.
