An overview of the parameters of the improved system for remote control of the gas situation during the elimination of fires in coal mines, as well as its design features and methods of application by the units of the mine rescue service is presented. It is indicated that the improved system makes it possible to control the gas situation by remote sampling of fire gases along the height and cross-section of mine workings at a safe distance, as well as to reduce the accumulation of condensate in the sampling pipeline and dry the air sample for the purpose of reliable express analysis of its gas concentrations.

The dependence of the consequences of fires on the time of arrival of the first fire Department is considered. The existing features of determining the location and arrival time of fire departments are considered. Approaches to optimizing algorithms for determining the arrival time of the first fire Department are proposed. The proposed approaches are based on categorization of exit areas and software based on map services. The positive and negative aspects of the methods are considered.

The paper reflects the influence of various factors on the height of the flame of solid combustible substances and materials, as well as the need to develop a method for determining this geometric parameter. Existing combustion methods for determining the geometric parameters of fires objectively reflect only the combustion process of combustible gases and liquids, since the height of the flame of such fires depends on the characteristic size of the fire source and the rate of entry of the combustible component in the reaction zone of combustion, which remain relatively constant over a long time. Combustion process of solid substances and materials is more complex and multi-faceted, so that the specific mass burn-up rate, and, accordingly, the height of the flame of such substances are not constant and depend on many additional factors.

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.

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.
