Detonators 12
Detonators 12 : The term commonly used to describe the device employed in initiating the decomposition of explosive compounds such as dynamite and blasting gelatin. Detonators generally require two types of explosives; one being sensitive to heat or fire, such as the safety fuses, which will explode a second more powerful charge that detonates or boosts to the principal explosive. Lead azide is commonly used as the first detonator because of its high sensitivity. The detonators are usually designed to attach to the safety fuse or another remote triggering device and are contained inside a tubular copper or aluminum case, with an attachment suitable for crimping. Detonators are commonly designed for electrical activation
