FIELD: fire safety.
SUBSTANCE: invention relates to fire extinguishing powder composition, which can be used for extinguishing fires of class A, B, C and electric installations. Fire extinguishing dry compound contains sylvinite and target additive, in form of synthetic mineral alloy of fractional composition, wt%: 100–150 mcm – 20–30, 40–50 mcm – 50–60, less than 40 mcm – 10–30. wherein sylvinite is 90.0–95.0 %, and synthetic mineral alloy 5.0–10.0 % of weight of composition. Invention also provides reduced toxicity and adherence to principles of resource saving.
EFFECT: technical result consists in uniformity of composition and properties of powder, high fire extinguishing properties and fluidity, reduced water absorption.
