FIELD: fire fighting, particularly aqueous fire-extinguishing foams based on surfactants and adapted to extinguish combustible materials and flammable liquids in open and closed spaces.
SUBSTANCE: fire-extinguishing composition comprises magnesium chloride hydrate taken as aqueous solution and water-based film-forming foam. Above components are taken in the following amounts (% by composition volume): magnesium chloride hydrate solution - 85-88%, water-based film-forming foam - remainder. Magnesium chloride content in the composition is 15-25% by composition weight.
EFFECT: increased efficiency fire extinguishment with low-expansion foam and reduced time of suppression of fires seated on horizontal and vertical planes, possibility of composition storage under low temperatures.
