Zusammenfassung:FIELD: fire-extinguishing equipment. SUBSTANCE: device has body with smoke discharging holes and accommodated in body charge with aerosol-forming fire-extinguishing composition with initiating unit and air ejector. The charge is made of at least two members and at least one of them is made of exothermal, while the rest of endothermal compositions with their weight ratio of (1-15):(0.5-2). Exothermal member is made of mixture, mas.%: potassium nitride, 65-75; phenol-formaldehyde resin, 10-20; and endothermal member is made of mixture of the same components in ration 50-40:10-40:40-50, respectively. The device compares favorably with the prototype by fire-extinguishing concentration by 1.15-1.7 times and by temperature of aerosol at the outlet by 2.4-3.8 times. EFFECT: absence of sparks and flame in operation. 4 cl, 1 dwg, 3 tbl
