In-hole and surface detonators are provided which are essentially free from primary explosives. The detonators utilize a high energy pyrotechnic mixture of a fuel and an oxidizer for initiation of a base charge enclosed in the detonator, or for the initiation of an adjacent shock tube.

In-hole and surface detonators are provided which are essentially free from primary explosives. The detonators utilize a high energy pyrotechnic mixture of a fuel and an oxidizer for initiation of a base charge enclosed in the detonator, or for the initiation of an adjacent shock tube. Improved safety during manufacture of detonators is achieved.
