Non-electric detonators are devices used to initiate explosives without the use of electrical energy. They typically rely on shock waves or chemical reactions to trigger the explosive material. These detonators are often preferred in situations where electrical interference or accidental detonation could pose a risk. These detonators can be classified into various types, such as shock tube systems and safety fuse igniters. Non-electric detonators are commonly used in construction, mining, and demolition, where safety and reliability are crucial. Their design minimizes the risk of unintended detonation, making them a safer choice in many applications.
