DEVICE FOR PREVENTION AND EXTINGUISHING OF FOREST, INDUSTRIAL AND EMERGENCY-TRANSPORT FIRES AND LAYING OF BARRIER STRIPS WITH FAST-HARDENING FOAM Russian patent published in 2019 - IPC A62C3/02 

FIELD: fire safety.

SUBSTANCE: invention relates to fire prevention and suppression of large-scale forest, peat, soil, steppe, industrial and emergency transport fires and creation of barrier strips ahead of fires at localization of upper and lower forest, soil, peat, steppe and other fires. Device for prevention and extinguishing of forest, industrial and emergency-transport fires and laying of barrier strips with fast-hardening foam contains sealed housing located in protective frame with possibility of accommodation in it of component A of fire extinguishing agent in the form of an aqueous solution of a mixture of sodium silicate and a synthetic hydrocarbon foaming agent and component B of the fire extinguishing agent in form of an aqueous solution of acetic acid, means for mixing components A and B of the fire extinguishing agent and foaming mixture of components A and B of the fire extinguishing agent to obtain fire-extinguishing substance in the form of a foamed silica gel forming a fast-setting foam, means of supplying components A and B of the fire extinguishing substance from the housing to a means for mixing components of the fire-extinguishing substance under action of pressure inside the housing, means for creating pressure inside the housing in the form of at least one solid-fuel gas generator placed in a sealed housing with the possibility of creating pressure during the combustion inside the housing.

EFFECT: higher efficiency of functioning and simplification of design with simultaneous improvement of its compactness.
