METHOD AND DEVICE FOR LOCATING AND/OR EXTINGUISHING FIRES

摘要

The present invention relates to a method for locating and/or extinguishing fires, wherein said method is mainly intended for fighting violent and large-scale fires in relatively inaccessible areas. This method comprises applying a combined action directly onto the fire region using a fine-dispersion air cloud (4) of a flame-retardant composition, an air shock wave (5) and a rapid air and detonation-product head which are all generated by the explosion of a dispersion load in a fire-extinguishing device (1) when the latter approaches the burning region. The fire-extinguishing device (1) comprises a vessel made of an ecologically clean material that is filled with a flame-retardant composition. The vessel is fitted with a dispersion charge and a sensor for a given parameter, such as altitude, said sensor being set at a given parameter (altitude) value. When the fire-extinguishing device (1) approaches the burning region and when the value is reached, the dispersion load explodes in a given fire sector. The dimensions and locations of the sectors where the fire must be extinguished are selected according to the type of fire and to the dimensions of the fine-dispersion cloud (4) of flame-retardant composition which is to be created.
