“…The approaches considered in the papers by Gurbanova [26,27] made it possible to assess the toxic effect on the environment of both inorganic components and organic components of foaming agents. At the same time, as an element of the integrated use of petroleum products, it should be noted the use of naphthenic acids as a component of a foaming agent [28] which surpasses fluorinated film-forming foams in terms of environmental characteristics.…”

The paper provides a review of up-to-date approaches for extinguishing oil and petroleum products. The variability of extinguishing methods and fire extinguishing agents is noted. Fire extinguishing agents used in extinguishing petroleum products are considered in more detailed way, and their environmental characteristics are discussed. The ambiguity of using various foams for extinguishing the fire is shown. A new method for extinguishing oil and petroleum products, based on the acoustic effect, and the capabilities of acoustic fire extinguishers for preventing and eliminating the combustible hydrocarbon fires, and their identification are analyzed. The further development of known approaches and the simultaneous emergence of innovative methods for extinguishing oil and petroleum products are shown. Keywords: oil; petroleum products; extinguishing agent; environmental characteristics; extinguishing foam; acoustic method.

“…The use of gel-forming compounds (GFC) allows the use of gel-forming compounds (GFC) to significantly reduce the loss of fire-extinguishing agent from blowing and deposition of powder particles when extinguishing fires in a pressurized space. Due to the adhesion of GFC to the surface of the fire extinguishing object, a fire-resistant layer of gel is created, which is quite firmly self-fixed on inclined and vertical surfaces, and this, in comparison with the use of other fire extinguishing agents, significantly reduces their losses [21].…”

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.

“…As a rule, water is used for extinguishing solid combustible substances, and water foam -for extinguishing flammable liquids [6,7]. However, in some cases, the possibility of using water-foam fire-extinguishing substances in the form of compressed air foam for extinguishing solid combustible substances has been proven [8] or to help protect forest resources from wildland fires [9,10], or in the form of a cooling two-layer foamed glass-gel material [11], etc.…”

The prototype of the compressed air foam system was improved based on the evaluation of the numerical parameters obtained with the help of the developed mathematical model of the foam generation process and the pneumatic-hydraulic scheme. The prototype provides the possibility of foam generation both in autonomous mode, due to the installation of cylinders with compressed gas, and in stationary mode, due to the supply of compressed air from an external source. This allows the use of an improved model of the compressed air foam system both in stationary mode (dry pipes, gas stations, etc.) and for use on heavy and light fire trucks, which is important for large cities. Testing of the improved prototype of the system for extinguishing model fires was carried out. The system provides extinguishing of model fires of class 183 B and 144 B when using both a general-purpose foaming agent and a special film-forming foaming agent. When using a film-forming foaming agent, the extinguishing time was reduced by 1.75 times, the consumption of fire extinguishing solution by 1.47 times. But at the same time, it should be taken into account that the cost of the film-forming foaming agent Sofir (sofirafff 6 %) is more than 3.2 times the cost of the general-purpose foaming agent Sofir. The effectiveness of the improved model in extinguishing class A fires was also confirmed. The autonomous compressed air foam system ensures extinguishing of a class 4 A model fire in 90 seconds. Dry foam with a factor of 14 is noted to be more effective in extinguishing solid combustible substances.
