Kalashnikov I. Scientific and methodological tools for assessing territorial risk at chemically hazardous sites

The dissertation is devoted to the development of effective methods for assessing the potential territorial risk of toxic and thermal damage to workers in case of emergencies at chemically hazardous sites. A methodology for assessing potential territorial risk in the event of extreme situations at potentially dangerous sites has been developed. For the first time, methods of spatial-temporal assessment of the potential territorial risk of toxic damage to humans in case of accidental emissions of toxic substances at potentially dangerous objects are proposed, which take into account the presence of buildings, chemical transformation of dangerous substances in the air. Methods for assessing the safe location of storages of chemically hazardous substances have been further developed, which also allow to quickly determine the safety zone for important objects in terrorist acts with the use of chemical agents. To assess the risk of toxic damage to workers in the workplace in the event of an emergency leak of chemically hazardous substances, a method has been developed to calculate the movement of hazardous substances in the respiratory tract of the employee when he inhales polluted air. The results obtained in the dissertation, developed methods and software packages are used in the State Emergency Service of Ukraine and in the educational process of the Dnipro National University of Railway Transport named after Academician V. Lazaryan. Key words: labour protection, territorial risk, potentially dangerous object, toxic damage to workers, thermal damage to workers, numerical methods, protection of work areas from chemical pollution, air curtain, air shower in the workplace, protective screens.
