An analysis of working conditions of rescue service and operational personnel during a fire has been conducted, when open fire is one of the dangerous factors, especially at the oil and gas object territories. It is also considered to be quite an important environmental factor, which under certain circumstances leads not only to deterioration of working conditions of operational personnel at a particular facility, but also to severe environmental pollution. This is especially true of firefighters, rescuers and other civil protection workers who are subjected to harmful effects of high temperature, thermal radiation, as well as hazardous combustion products while eliminating emergency situations. Improvement of working conditions during emergency rescue operations can be achieved by reducing their conduct time, as well as by increasing a distance between a rescuer and ignition point. This can be achieved by using fire extinguishing solutions with additives of surface active agents and polymers in fire suppression systems. These substances are introduced into fire hoses and pipelines, which allows to increase the expense of extinguishing solution, flow range from the jet nozzle and reduce duration of fire suppression operation. The laboratory conducted experiments allowed to select a specific polymer - polyethylene oxide, its molecular weight and solution concentration, which provides the maximum possible reduction of hydraulic resistance in a fire hose and a jet nozzle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
