FIELD: fire-fighting compositions.
SUBSTANCE: powder comprises wastes of cooking salt production having particle dimensions of less than 0.2 mm taken in amount of 90.0-95.0% by weight and hydrophobically-modified porous silicate taken in amount of 5.0-10.0% by weight. Porous silicate is silicon dioxide, Circulite, bentonite, vermiculite or silicate industry waste hydrophobizated with 3-8% solution of methyl-trichlorosilane in toluol or in another inert organic solvent.
EFFECT: increased fire-extinguishing capacity and fluidity.
