“…Research papers [11,12] state that the wood pyrolysis results in the formation of the wood char and also liquid and gaseous products. Liquid products leave the hot zone partially in the drop phase partially in vapors and in combination with uncondensed gases form the steam-gas mixture.…”

Consideration was given to the issue of the integrated evaluation of the flammable properties and factors of wooden products (Oriented Strand Boards, OSB and Wood Particle Boards, WPB) as basic flammable construction materials exposed to the action of fire. The experimental data obtained for flammable wooden products during the experiments carried out to define the dependence of temperature on the time of fire impact, to measure and substantiate the charring depth of wooden products, to determine degradation zones affected by fire and their sizes (area, width and length) and to compare a change in the specimen mass before and after the tests have been given. The experimental data confirm and substantiate the pyrolysis processes of wooden products during the fire spread.

“…It should be noted that synthetic materials can potentially release twice as much thermal energy during the combustion. Under the action of thermal energy, these materials are much easier decomposed into the fuel in a gaseous aggregate state capable of burning [24]. The products of the thermal decomposition of the synthetic fuel are also subject to much easier inflammation in comparison to the products derived from the natural fuel [8,25].…”

Consideration was given to the issue of flammability during the thermal decomposition of synthetic materials used for the constructions to isolate the process equipment and building structures. The experimental research data obtained for the thermal decomposition of synthetic materials with the measurements of temperature as a function of the time of thermal radiation were given including a change in the mass and structure of the specimens of synthetic materials exposed to the thermal radiation during the fire. The obtained experimental data enabled the substantiation of the process of the thermal decomposition of synthetic materials depending on time and temperature and also a change in the mass of the specimens of synthetic materials before and after the tests.

“…Moreover, the undercarriage space is an almost inaccessible location of the indicated fire load [5]. In addition, it must be said that the main part of the materials and equipment of the wagons contributes to the rapid spread of the flame and the spread of the leakage of toxic gases, which create a danger of poisoning people with combustion products in the event of a fire [6], injury and death of personnel [7,8], lead to the destruction and damage of industrial facilities [9], pollution of atmospheric air [10,11], surface water and grounds [12,13]. All this determines the corresponding difficulties in carrying out work for fire-rescuers [14].…”

For operational extinguishing of fire-hazardous equipment under a subway car, a modernized under-weight extinguishing trolley is proposed. For supplying components of gel-forming compositions Na2O·2,7SiO2 + NH4H2PO4 sprayers of the "segener wheel" type were used. This made it possible to create a finely dispersed fog of gel-forming compounds under the subway car, ensuring uniform and stable adhesion of the gel layers to all surfaces under the car. When conducting experimental studies on the extinguishing of model fires, which are close in their configuration to a sub-weighted space, the effective parameters of the dispersion of drops of gel-forming compositions in 1,6 mm were determined. Uniformly stable adhesion of gel-forming compositions when finely dispersed allowed to reduce the consumption of fire extinguishing agent by at least 25% compared to previously used technical solutions.
