What is a Safety Firing Head?

The Safety Firing Head offers a method of mechanical activation for setting bridge plugs, perforators or other devices without the use of E-Line. The tool relies on downward jarring to sever a shear pin allows a firing pin to activate a charge in the tool connected beneath the Safety Firing Head. To avoid unplanned activations of charges at surface this tool comes equip with a safety sleeve which can be threaded against the top sub which effectively disables the shear mechanism. When the tool is ready to be lowered into the well bore the safety sleeve is threaded away from the fishneck which allows the shear pin to be sheared upon downward jarring.
