The main regulatory requirements in the field of fire safety of sports complexes are considered. It is noted that when forming fire safety requirements for sports complexes, it is also necessary to take into account the requirements of sports organizations. The main technical and design solutions of modern sports complexes are considered. Based on the analysis of the fire hazard of the sports complex, fire scenarios were selected and field modeling of the dynamics of the spread of fire hazards was carried out. The results of calculations of evacuation time for various scenarios are presented.

The article presents a study of the heat resistance of intumescent flame retardants for hydrocarbon combustion conditions by synchronous thermal analysis. The results of the study are shown for a composition based on a silicone binder and compositions modified with silicon-containing components – wollastonite and aluminosilicate microspheres. Further, the data were compared with the indicators obtained during fire tests to determine the fire-retardant effectiveness in the installation for testing the fire-retardant effectiveness of fire protection equipment. The study showed that the fire-resistant compositions that showed the best result in tests for fire-resistant effectiveness also have a higher degree of heat resistance, which indicates the possibility of using the proposed method as a means of evaluating the “ productivity” of fire-resistant materials of the intumescent type.

The article describes the device and the procedure for working with the installation, which allows you to obtain information about the distribution of fire extinguishing powder at the control points of the cross-section of an unsteady gas stream. Such information can be used to increase the efficiency of extinguishing a fire source using powder fire extinguishers by regulating the distribution of fractions in the gas-powder stream.

Questions are presented on a special assessment of the working conditions of a repair facility and the State Institution of the Russian Ministry for Emergencies in St. Petersburg (units of the federal fire service). The hazard characteristics of workplaces are considered, comparisons of the degree of danger and the severity of work of workers (minimum, average and maximum) are given.

Problems of estimation and calculation of social fire risk based on statistical data are considered. Social fire risk was assessed for groups of similar objects (five-storey and nine-storey residential buildings). It is shown that the obtained estimates of social fire risk do not differ for five-story and nine-story residential buildings. It is concluded that when assessing the social fire risk, it is not the number of people in the building that is important, but the number of people at risk who are exposed to fire hazards.
