The complex research method is used in the work, which includes: analysis and generalization of scientific achievements in the field of fire safety, application and processing of statistical data; application as analytical methods of research by collecting, generalizing and analyzing the current normative documents of the State Emergency Service of Ukraine and statistical methods of probability theory, geospatial, mathematical modeling, methods of system analysis. Research Object: The risk of death from fire in public buildings and structures. The purpose of the work is risk evaluation of death from fires in public buildings. Research methods. The complex method of researches is used in the work, which includes: analysis and application of statistical methods of data processing, verification of reliability of the obtained results, mathematical modeling and other analytical methods. The concept of the risk is described in the article and the main normative documents are outlined that treat them. The basic methods and methods of risk assessment for public buildings are analyzed. Fire risk assessment is the calculation of individual fire risk for residents, staff and visitors in a public building. The numerical expression of an individual fire risk is the frequency of exposure of hazardous fire factors to a person in a building or structure. The frequency of exposure to hazardous fire factors is determined for fire-hazardous situations, which are characterized by the greatest danger to the life and health of people in the building. The CFAST program simulated the occurrence of limit concentrations of hazardous factors during fires for two typical public buildings. It is also suggested how to evaluate the results on a specific color scale that allows you to create risk maps for visualization. The draft methodology proposes to consider the follow-up time of fire and rescue units when determining the evacuation time. The main methods and methodologies of risk assessment for buildings and public facilities have been analyzed. For two facilities, the risk of death from fire in buildings and facilities has been estimated. The results of evaluation have been suggested in a color scale, which allows creating maps to visualize the risks. The simulation of the limit concentrations of hazardous factors during the fires for two typical public facilities has been done in CFAST software. Mapping the risks of death from a fire in the appropriate group in the appropriate colors allows you to build a map of the risks of death from a fire and fire and rescue workers know the possible risks and dangers of the objects. The start time of the evacuation, in the absence of warning systems, is determined depending on the time the fire and rescue units follow to the fire site. The proposed calculation methodology and visualization tools allow the rescuer, who makes the decision, to comprehensively assess the situation during the design and to avoid the possible consequences of an emergency, which will increase the level of security.
