Abstract
The invention relates to a security device forming a pressurized gas release valve, said device including a body that defines a gas flow channel extending between a first upstream end, to be placed in contact with a source of pressurized gas, and a second downstream end, to be placed in contact with the outer atmosphere, the device including a stopper that is located on the channel so as to prevent the flow of the gas between the upstream end and the downstream end in a normal situation, the stopper being fusible and/or frangible so as to release the gas passage in the event of a dangerous situation when a pressure and/or a temperature exceeds a predetermined threshold. Said device is characterized in that said device includes a tank of an unstable, exothermically decomposable gas that is placed in communication with the pressurized gas released during the melting/breaking of the stopper.
