Reviewing the history of the development of preventing measures, to ensure suppression of fire clearly reveals, that the most urgent of these measures is the use of environmentally friendly, highly efficiency fire extinguishing means. The best fire-extinguishing means are fire-extinguishing powders, which are characterized by high effectiveness and universality. Fire- extinguishing powders of serial production represents the fine dispersed mineral salts with different additives, which decrease tendency of consolidation and caking of powder. In serial production powders halogen containing, organic hydrophobizators are mainly used as such additives. Thus, most of them are halogen containing and do not satisfy the contemporary demands, in the first place with the view of effective, non-toxic and universal use. It also should be mentioned, that fire- extinguishing powders are characterized with less heat capacity, low permeability and wetting effect compared to water and foams, that’s why at extinguishing large scale fires, particularly - forest fires, use of just fire- extinguishing powders is less effective. This article discusses the elaboration of non-halogen, environmentally friendly, high-efficient, universal fireextinguishing powders on the basis of local mineral raw materials of silicate origin and production of highly effective foam-suspensions based on such powders, the use of which will have higher extinguishing ability than water, foams or powders taken separately. The received fire-extinguishing powders will be used at extinguishing of all classes of fires, as well as, in complex with water and foams for extinguishing of large scale fires – forest fires.
