METHOD OF FOREST FIRE SITE LOCATION Russian patent published in 2008 - IPC A62C3/00 

FIELD: agriculture.

SUBSTANCE: method of forest fire site location implies specifying the most fire-hazardous peatbog sectors, installing vertical perforated pipes on the sector area, filling the pipes with smoke-forming pyrotechnic composition, putting the pipes coordinates onto a forest fire map, developing patrol routes, patrol smoke monitoring, specifying the fire boundaries according to the location of smoke over the pipes, fixing its coordinates on the forest fire map. Feature of novelty consists in the fact that prior to installation of the perforated pipes the lower pipe ends are flattened, then waterproof thermoplastic cases are put into the pipes, the cases are filled with smoke-forming pyrotechnic composition and the pipes are forced vertically into the peat layer. The cases are made out of polymer film 80-100 mcm thick, for example polyethylene or polyvinylchloride.

EFFECT: increasing accuracy of locating boundaries of underground fire on peatbogs by 60% and reducing labour intensity due to unnecessity of boring wells.
