Abstract
The conditions of suppression of flame combustion and thermal decomposition in model forest and peat fires using water, foam concentrate emulsion (5%), bischofite solution (10%), FR-Les 01 solution (20%), flame retardant solution (vol. 5%), OS-5 solution (15%), and bentonite slurry (5%) were determined. Temperatures in the process of ignition of model fires and extinguishing of the latter by specialized water-based compositions were measured. Minimum volumes of the extinguishing compositions and the time necessary and sufficient to suppress the pyrolysis of plant biomass were established. Minimum irrigation densities of model forest and peat fires using water-based compositions with specialized additives were determined.
