ABSTRACT:
An improved safe-arm method and apparatus is provided for preventing unwanted detonation of shaped charge perforating guns while in storage and in transport, yet providing quick and easy arming at the well site. An interrupter member is inserted within an air gap between an ignitor section and an explosive charge section. To ready the perforating gun for use, a lanyard connected to the interrupter and extending externally from the perforating gun housing is pulled, removing the interrupter from the gap and arming the perforating gun section.
