FIELD: fire safety.
SUBSTANCE: in the combined fire extinguishing method, which includes the supply of an inhibitive aerosol and a fire extinguishing powder simultaneously from the fire extinguishing device as a flow of fire-extinguishing powder, sprayed in a cooled inhibitive aerosol. The said flow speed is limited down to values, where its finely-dispersed system remains sedimentation stable, at the outlet of the fire-extinguishing device this flow is additionally mixed in a blade apparatus, and nano-powder is used as the fire-extinguishing powder. In the fire-extinguishing device, containing a body with a charge of aerosol-forming composition and firing point, a heat-absorbing device, filled with material for cooling the aerosol and a polymer shell with fire-extinguishing powder, installed behind the heat-absorbing device, a device for discharge of aerosol and fire-extinguishing powder, in which the membrane is made in the form of a grid and there is a blade apparatus in its outlet for additional mixing of the flow, sprayed in the cooled inhibitive aerosol of the fire-extinguishing powder, and the fire-extinguishing powder is made as a nano-powder.
EFFECT: effective fire extinguishing of different classes.
