COMBINED METHOD OF ISOLATION AND EXTINGUISHING CREEPING FOREST AND GRASSLAND FIRES

摘要

FIELD: fire-fighting means.;SUBSTANCE: method is implemented with the help of pressure hose charge. At a safe distance for operators-fire fighting personnel from the fire-front a reference surveying rod is set. In accordance with the intensity of the fire the flame height is estimated, and the charge is placed behind the surveying rod at a distance Δ in the direction of fire. The distance Δ is determined by the ratio where: T₁ - is flame temperature, T* - is the temperature of destruction of the charge shell, T₀ is the temperature of the environment, H - is height of the flame, T' - is temperature of the pyrolysis zone. When approaching the edge of the fire to the reference surveying rod the charge is exploded. Certain flame sources are extinguished with a disintegrator.;EFFECT: combined method allows to increase the effectiveness of firefighting and provides safety of operations.;4 dwg
