The fire-fighting charge is designed for remote fire extinguishing in inaccessible or difficult to access and remote fires. It comprises a spherical casing (1), filled by fire-fighting powder (2). Inits geometrical centre a explosive charge (4) is fitted, which is firing connected to a propellant charge (9) with an electric fuse (10), fitted in a cylindrical volume under the spherical casing (1)by means of a pyrotechnic delayed action charge (5), ending by firing accelerator (7) immersed into the charge (9). By firing from the staring installation the delayed action charge (5) is ignited, which after its burning during the flight ignites the explosive charge (4) causing the explosive destruction of the casing (1) and the complete spreading of the fire-fighting powder (2) over the fire of the fire to which the charge (1) has been directed. Charge (9) can be replaced by an explosive gaseous mixture.
