A mechanism ( 10 ) for releasably confining pressurized fluid in a container ( 18 ) is provided. The mechanism includes a rupturable membrane ( 22 ) in is fluid communication with an interior of the container ( 18 ), thereby exposing the membrane ( 22 ) to the fluid. The membrane ( 22 ) is configured to obstruct flow of the pressurized fluid when externally supported against pressure exerted by the fluid. The membrane ( 22 ) is also rupturable by pressure exerted by the fluid when not externally supported against the pressure exerted by the fluid. A support member ( 28 ) is provided for externally supporting the membrane ( 22 ) against pressure exerted by the fluid. The support member ( 28 ) is configured to be fracturable upon exposure to combustion products formed by activation of a gas generator (66) at least partially encased within the support member ( 28 ).
