ANALYSIS OF THE AVAILABLE SUBSTANCES USE AND METHODS OF THEIR DELIVERY FOR FIRE EXPANSION
Every year from fires there is a set of accidents, considerable material losses are put, the environment is destroyed, people perish. In recent years, there has been a tendency to increase the occurrence of significant fires in arsenals, oil storage facilities, chemical plants, which requires fundamentally new approaches to their elimination. The question of effective work of the personnel of the state emergency service of Ukraine in various destructive situations and the minimum risk to their lives is relevant.
In the reviewed work the authors analyzed the use of fire extinguishing agents and methods of their delivery for fire fighting purposes. The advantages and disadvantages of the use of various fire extinguishing agents. The idea of optimal extinguishing of complex fires with the help of discrete delivery of various fire extinguishing substances by fire-rescue units over long distances (more than 100 m) is proposed, a drawing of the method of their supply is given and an example of a container (container) that delivers the fire extinguishing agent to the fire place is developed. The existing target model of fire extinguishing requires further careful research, especially in the field of ballistics and design of the container (container) for the delivery of various fire extinguishing agents, which make an error in the results, but will help to solve the actual problem of effective fire extinguishing. The analysis shows that many different types of fire extinguishing agents have been developed, but a universal fire extinguishing agent that would meet the requirements of efficiency, environmental safety and fire extinguishing efficiency, and most importantly to extinguish all classes of fires is not developed. Therefore, the goal of further research is the modernization of the methods of delivery of these agents. Modern methods of extinguishing fires by supplying fire extinguishing agents are not always safe for the life of firefighters-rescuers, so we believe that the use of methods and devices for supplying fire extinguishing substances from a safe distance is a priority for the development of fire fighting. As one of the directions of solving the problem of extinguishing fires of different classes from a safe distance, it is proposed to use stem installations for discrete supply of various mixtures of fire extinguishing substances.
The results of the research presented in the reviewed work are of theoretical and practical interest, and therefore are promising for study and can be recommended for publication in scientific journals.
Keywords: extinguishing agent, installation of a discrete supply of extinguishant substances, fire extinguishing.
