PREPRODUCTION TESTING OF EXTINGUISHING EFFICIENCY OF A NOVEL WATER-BASED FIRE-EXTINGUISHING AGENT ON BASIS OF K2[CuCl4] COMPOUND

Abstract

The results of laboratory research related to fire-extinguishing action on hydrocarbon flame by aqueous solutions of potassium tetrachlorocuprate(II) at different concentrations are presented in the article. The short-lived influence on front of hydrocarbonaceous flame by aerosol of the aqueous solution (40%) of complex salt of copper(II) – K2[CuCl4] leads to full extinction of burning. A minimum expense of 40% aqueous solution of the potassium tetrachlorocuprate(II) on extinguishing of fire source (B2 class) amounts to 1.1 L/m2. It is ascertained that in case of extinguishing of the inflammations of the various hydrocarbons by means of K2[CuCl4] aerosol (40% aqueous solution) consumption of this water-based fire-extinguishing agent were 4.2 (ethanolamine’s flame) or 3.2 times (hexane’s flame) less than by water aerosol.
