The task of effectively extinguishing fires during fires is relevant. Its solution is related to the problem of a safe non-toxic flame arrester. There are various principles for extinguishing fires [1].

Isolation of the source of combustion from the access of air occurs when inert (not supporting the combustion process) gases and other materials are supplied to the combustion zone. In another case, substances that can take heat due to the evaporation process (water, freons) or substances capable of an endothermic decomposition reaction (ammonium phosphate, crystalline hydrates) are fed into the combustion zone. Inhibitors of radical oxidation-reduction processes containing halogens, phosphorus, salts of potassium and sodium.

The use of metal-containing compounds (red and yellow blood salts) [2,3], in particular, 30% aqueous solution of K3 [Fe (CN) [Fe (CN) 6] (red blood Sol ) [4].

As additives to aqueous solutions, when using aerosols, such compounds as NaCl, KCl, LiI, CH3COOK, CoCl2, NiCl2, NaOH, NaHCO3, MgCl2, CaCl2, MnCl2, FeCl2 and others were added. Some of these compounds have been found to be more effective inhibitors of combustion than freons such as CF3Br. However, the most effective flame arresters are complex compounds of potassium and iron [5].

A good effect is extinguishing with the help of submicron aerosol of aqueous solutions of red and yellow blood salt. This technology can be used to extinguish large-scale foci of flame, including the fire of a wooden structure and a tank with oil products [6].

It is known that the most effective is the extinguishing of fires of flammable liquids with powder compositions. One of the new proposals of the composite composition of fire extinguishing powders is the introduction of alumino-potassium alum into the composition of the basic salt, which reduces caking and increases the fluidity of the powder. At the same time, fire safety of equipment and apparatus at chemical and oil refineries is optimized [7].

A good effect of extinguishing with powder substances is provided by the inclusion of an additive in their mixture: zinc oxide (dusting of the composition, reduction in caking of the powder, ensuring flowability),potassium alum (provide the necessary fluidity of the mixture) and alumina (helps to cool the combustion zone).

New patent research based on the patentological approach [8] can optimize the creation of modern patent technical solutions for extinguishing forest fires. Patentological approach is used in the development of new production technologies [9], in the implementation of design developments [10].
