A jet cutter venting apparatus and method for venting gases generated during deflagration. The venting apparatus and method including vent grooves inside the jet cutter providing a pathway for deflagration gases to escape. The venting apparatus and method also may include using notches or holes placed inside the jet cutter to facilitate the venting of gases during deflagration. The venting of the gases during deflagration facilitates pressure relief within the jet cutter and increases safety from accidental detonation during a fire.
