A fire extinguisher includes a body defining a storage chamber containing an extinguishing agent, a gas generator configured to pressurize the extinguishing agent in order to dispense it outside the body through an exit opening. The exit opening is equipped with a misting nozzle, and the extinguishing agent has a solidification temperature less than &#x2212;10&#xb0; C., the saturating vapor concentration of the extinguishing agent taken at &#x2212;10&#xb0; C. and at 1 bar being less than the extinguishing concentration of the extinguishing agent determined according to the ISO 14520 standard for a heptane fire at 1 bar.

A breaker device for connecting in an electrical circuit, the device includes a pyrotechnic initiator and a body having present therein: a pressurizing chamber in communication with an outlet from the pyrotechnic initiator; at least one electrically conductive portion for connection to the electrical circuit; at least one fusible element connected in series with the conductive portion, the initiator being connected to the terminals of the fusible element and the fusible element being configured to trip when the current passing through it exceeds a predetermined value, thereby actuating the initiator; and a movable breaker element; the pyrotechnic initiator being configured to cause the breaker device to pass from a current-passing first configuration to a circuit-breaking second configuration, the movable breaker element being moved on passing from the first configuration to the second in order to disconnect the conductive portion.

The present invention relates to a process for the self-regulated production as a function of the demand, under submerged conditions, of a gas (G), said gas (G) being generated by a chemical reaction between a liquid (L) and a solid (S) (hydrogen generated by hydrolysis of a metal hydride, for example) and not being polluted between the generation thereof and the delivery thereof. The present invention also relates to a device suitable for the implementation of said process.
