Application experience and aspects of improving the temperature activated water technology for extinguishing fires and preventing emergencies

Abstract

Introduction. The article considers the experience of application and aspects of improving temperature activated water technology for extinguishing fires as well as preventing and eliminating accidents. The technology for generating temperature activated water is described. The areas of the technology application have been explored. The advantages, disadvantages and some aspects of the technology improvement are presented. The purpose of the study is increasing efficiency of fire extinguishing and emergency prevention via using temperature activated water technology. Development of new technical means for supplying temperature activated water and fire extinguishing agents based on it. Research methods. To obtain the results, general scientific methods of cognition were used – analysis, synthesis, the theory of water boiling and hydro-gas dynamics. Reliability of the results presented in the given work is confirmed by application of the fundamental laws of physics and the proper mathematical tools. The results of the study. The advantages, disadvantages and some aspects of technology improvement are presented. It was explored that temperature activated water in a suspended state is able to dilute and cool the combustible medium and displace the oxygen of the air in enclosures, thereby eliminating the fire. The supply of hot water through hose lines over long distances (no more than 2 km) without loss of quality properties makes it possible to use the technology when extinguishing fires in hard-to-reach places. Low water consumption for extinguishing fires (up to 40 minutes without refueling) has a positive effect on extinguishing fires under conditions of limited water supply. The results of scientific research have been introduced into new models of appliances capable of performing a huge range of tasks set by EMERCOM of Russia. Conclusion. The information presented in the given publication will help managers and users of the technical means based on the temperature-activated water technology to apply and use it correctly for extinguishing fires and eliminating emergencies. The article discusses new aspects of the application, which allow us to suggest the possibility of extinguish fires, preventing and eliminating accidents in underground mine workings, subsurface suppression of municipal solid waste landfills, and extinguishing live electrical installations with temperature-activated water. The main directions for improving the technology are development and creation of new technical means for generating and supplying temperature-activated water and fire extinguishing agents based on it, as well as the study of its application at various protection facilities, including those located in the Arctic zone of the Russian Federation.
