A blasting cap is a small explosive device used to initiate a larger explosion. It typically contains a sensitive explosive material, such as lead azide, which detonates when triggered by a fuse or electrical signal. Blasting caps are commonly used in construction, mining, and demolition to safely control the timing and intensity of explosions. These devices are crucial for ensuring that larger explosives, like dynamite or ANFO, detonate in a controlled manner. Proper handling and storage of blasting caps are essential to prevent accidental detonations, making them a vital component in industries that rely on controlled explosions for tasks involving heavy materials or rock removal.
