Abstract
Introduction. Extinguishing fires in buildings causes the need for firefighters to carry out actions in conditions of limited visibility and unsuitable for breathing environment. To ensure fire safety of buildings of increased complexity and basements of complex layout, it is necessary to equip fire protection units with breathing apparatus with extended protective action time. The decision on equipment is made by the head of the territorial body of EMERCOM of Russia. However, at the moment there are no methods and criteria for assessing the degree of complexity of buildings in terms of the actions of fire departments. Accordingly, the person making the decision on equipment is based only on experience in extinguishing similar fires. Goals and objectives. The aim of the study is to develop a model for assessing the degree of complexity of buildings to support decision-making in extinguishing fires. To achieve this goal, it is necessary to develop a model and methodology for assessing the degree of complexity of buildings for firefighters in an inhospitable environment. Methods. In the course of this study, a graph model was used to formalize the description of the degree of complexity of the building. The complexity assessment was carried out according to four parameters relative to the average value obtained for all the studied objects. Simulation modeling was used to assess the reliability of the research results. Results and its discussion. A model and methodology for determining the spatial degree of complexity of the task for the actions of fire departments have been developed, which allow determining the relative complexity index. The comparison of the results of the assessment of the degree of complexity of buildings with the time of the survey by gas and smoke protectors obtained as a result of the simulation modeling was carried out. Conclusions. The application of the results of the study will allow the decision-maker to determine the degree of complexity of buildings, which is necessary when choosing breathing apparatus with an extended protective action time and when predicting the likelihood of large (from the point of view of extinguishing tactics) fires. Keywords: degree of complexity of the building, fire protection units, large fires, graph model, assessment methodology.
