FIELD: fire safety equipment.SUBSTANCE: invention relates to the field of fire-extinguishing and can be used to extinguish fires at various sites both in indoor and outdoor spaces. The method of fire extinguishing consists in main large-drop fire-extinguishing liquid and atomised fire-extinguishing liquid alternately applied to the combustion source, forming the aerosol cloud on the surface of the combustion source, and the subsequent pressing of the aerosol cloud to the surface of the combustion source. Pressing of the aerosol cloud is carried out by additional supplying a portion of the large-drop fire-extinguishing liquid. The additional large-drop fire-extinguishing liquid is supplied onto the combustion source in an amount equal to 10-50% of the amount of the main large-drop liquid.EFFECT: method enables to increase the efficiency of fire-extinguishing with sprayed fire-extinguishing liquid, especially fire with powerful upward heat fluxes, to provide the ability of extinguishing fires in premises with low and high altitudes.6 cl |
