FIELD: medicine, life saving equipment.
SUBSTANCE: method of volume firefighting and related equipment enables to increase efficiency of firefighting procedures due to decreased temperature and losses of fire-control aerosol by introduction thereof with pyrotechnic composition resulted from combustion, thus charges are inflamed from lower non-reserved end face, and produced aerosol is let through channels between charges and through cellular plaster filter. Thereafter aerosol is exhausted to protected volume through clearances of outlet cone. Firefighting unit consists of working body, injector assembly and two fire-resistant grids, and also contains block cellular plaster filter for aerosol cooling, mounted between fire-resistant grids, and outlet cone for uniform distribution of produced aerosol.
EFFECT: provided increase of firefighting efficiency.
