Abstract: The object of the inventive method and device for controlling and/or extinguishing fires is to extend the range of means for transporting devices to a fire site, substantially reduce the time for the operating preparation thereof and to exclude a fragmentation field caused by the device explosion which ensures the momentary conversion of a fire-extinguishing composition into a fine cloud associated with a simultaneous airblast effect produced to a fire area and a maximum distribution of said fire-extinguishing composition through the fire volume. Said method for controlling and/or putting out a fire consists in effecting the fire area by an airblast and the high-speed flow of the air-dispersed mixture of the fire-extinguishing composition (7) produced by the explosion of a fire-suppressing device (2) which comprises a dispersing charge (8) and a container (6) with the fire-extinguishing composition (7).
