FIELD: fire safety; nanotechnology.
SUBSTANCE: invention relates to nanotechnologies in the field of fire-fighting equipment. Proposed technical solution is easy in operation and can be used in a normal powder fire extinguisher using in its operation in series both the volumetric extinguishing method with the use of nanopowders with a considerable inhibitory action on the flame, and the method of extinguishing throughout the surface of burning materials and substances with the help of a powder fire-extinguishing substance made in the form of a coarse fire-extinguishing powder for final extinguishing of repeated combustion spots due to insulation of the burning surface and termination of the air oxygen access to the burning materials at all levels of combustion.
EFFECT: proposed technical solution can be used to feed powder fire-extinguishing substances of various dispersion to the fire source in zones with presence or absence of people.
