Influence of the Density of a Forest Combustible Material on the Suppression of its Thermal Decomposition by a Liquid Aerosol

Experimental investigations on the characteristic time of suppression of the thermal decomposition of the soil cover of coniferous and foliage forests and on the volume of water required for this purpose have been performed. Experiments were conducted with samples of typical forest combustible materials (birch leaves and spruce needles) of different densities under conditions characteristic of a forest fire extinguished by a liquid aerosol with the use of modern fire-extinguishing means. It was established that it makes no sense to increase the volume of water used for suppression of the ignition of a forest combustible material whose density exceeds a definite limiting value.
