Abstract

The present invention relates to a fire-fighting device that comprises: - a casing (2) that defines an inner cavity (3) in which at least one dispersible extinguishing agent (4) is deposited, and - pyrotechnic means (5) suitable for generating an explosion causing the casing (2) to rupture and the extinguishing agent (4) to be dispersed, the pyrotechnic means (5) comprising: - at least one explosive charge (6), generating the explosion, and - detonating means (7) intended to trigger the explosion of the at least one explosive charge (6), and the detonating means (7) comprise: - an ignition device (8) designed such that, in an active state, it triggers the explosion of the at least one explosive charge (6), and - an impact sensor (9) designed to detect a mechanical impact received by the device (1) and to place the ignition device (8) in the active state when the mechanical impact is detected.

IPC Classes  ?

• A62C 3/02 - Fire prevention, containment or extinguishing specially adapted for particular objects or places for area conflagrations, e.g. forest fires, subterranean fires
