On the basis of experimental studies it was revealed that adding of electrolyte - ammonium chloride - into solution of film-forming foaming agent leads to decrease of interfacial tension on a border with heptane, and increase of surface tension on a border with air. It is experimentally shown that dependence between specific consumption and flow rate of foaming agent passes through the minimum point that allowed defining influence of electrolyte on a value of minimum specific consumption and optimum flow rate of foam during extinguishing of a hydrocarbon flame. The structure of spreading in a foaming agent solution – hydrocarbon system defines the value of fire extin-guishing efficiency of foam decreasing together with lowering of spreading coefficient and interfacial tension.
