Zusammenfassung:	A double safety firing system comprises: a firing line, wherein an end of the firing line is directly or operatively connected to an electrically-activated initiator; a first safety sub-assembly, wherein the first safety sub-assembly is connected to the firing line and comprises: a first shunting line; and a first shunt disabler, wherein the first shunt disabler disables the first shunting line when a predetermined amount of force is applied to the first shunt disabler; and a second safety sub-assembly, wherein the second safety sub-assembly is connected to the firing line and comprises: a second shunting line; and a second shunt disabler, wherein the second shunt disabler disables the second shunting line when a predetermined amount of electric current is applied to the second shunt disabler, wherein after the first and second shunting lines are disabled, electric current flows through the firing line and activates the initiator.
