FIELD: fire safety. ^ SUBSTANCE: invention relates to fire extinguishing compositions, which can be used in fire-fighting classes A2, B, C, D. Fire-fighting powder composition contains potassium chloride, water-proofed, and muscovite with a particle size less than 10 microns in the following ratio, wt %: Potassium Chloride - 93.8 - 96.0; muscovite - 3.5 - 5.0; metiltrihlorsilan - 0.07. ^ EFFECT: due to using muscovite as additive, having high moisture resistance, and one of the best insulating materials, extinguishing powder has a low caking and effective for extinguishing electrical installation, under voltage up to 5000 V and higher (with safety factor 2). ^ 1 tbl, 3 dwg |
