When handling packages of explosives, what must you never use?

When handling packages of explosives, it is crucial to avoid using hooks or other metal tools. This is because metal can create sparks, which pose a significant risk of igniting the explosive materials. The potential for a spark from metal tools to cause an accident is a critical safety concern in the handling of explosives.

Using alternative materials like plastic tools can be safer as they do not generate sparks. Gloves and wooden pallets, depending on the context and materials used, can be compatible with safety protocols, provided they do not introduce additional hazards. Therefore, avoiding metal tools is imperative to ensure the safe handling of explosives and to minimize the risk of unintended detonation.
