The invention relates to low temperature fire extinguishing compositions and reduces corrosivity. The composition includes May. %: potassium acetate 40-45, sodium silicate 0.05-0.2, sodium tetraborate 0.1-0.5, and water the rest. The corrosion activity of the composition for stainless steel decreases from 2.4 10 to 5 g / m3 per day, for the AMg-3 alloy from 2.5 101 to 0, and for alloy D-16 from 7.5 to 5 g / m3 in 1 days |
