Blasting caps are small explosive devices used to initiate larger explosives, such as dynamite. They contain a sensitive explosive material that detonates when triggered by a fuse or electrical signal. Blasting caps are essential in construction, mining, and demolition, where controlled explosions are necessary. These devices come in various types, including electric blasting caps and non-electric blasting caps. Electric caps use an electrical current to ignite the explosive, while non-electric caps rely on shock waves from a detonator. Proper handling and safety measures are crucial when using blasting caps to prevent accidental detonations.
