A system for detecting gas leakage within a battery pack includes a battery pack, a controller, and a detector. The battery pack comprises a plurality of cells which may be subject to a gas leakage. The detector is remotely mounted from the battery pack and is connected to the battery pack via airtight tubing. A fan conducts air from the battery pack to the detector. The detector is configured to read a concentration value of one or more gases. The detector is electrically connected to the controller and is configured to a return signal indicative of no alarm, a first alarm level, or a second alarm level to the controller. The controller is configured to output no alarm, a first alarm level or a second alarm level in response to the return signal. Emergency response procedures are implemented based on the level of gas leakage within the battery pack.

A valve assembly for a pressure vessel is disclosed that includes a valve housing operatively associated with an outlet of the pressure vessel, a frangible hermetic disc sealing the outlet of the pressure vessel, and a poppet valve mounted for movement within the valve housing between a first position supporting the frangible hermetic disc within the outlet of the pressure vessel and a second position spaced apart from the frangible hermetic disc to permit the frangible disc to burst under pressure and permit the egress of pressurized material from the pressure vessel through the outlet.
