The article provides data on the use of pumping and hose systems by fire and rescue units in the Siberian Federal District over the past three years. The analysis of the data is carried out and the shortcomings of the existing pumping and hose systems noted by the Main Directorates of the Ministry of Emergencies of Russia of the subjects of the Siberian Federal District from 2017 to June 2020. Based on the results of the analysis of the use of tubing systems, conclusions were drawn on the future development of these systems.

The article is devoted to the features of depressurization of the fuel system of motor vehicles in conditions of low temperatures in the sharply continental climate of the Siberian region. The mechanism of destruction of fuel lines made of polymer materials as a result of reducing the elasticity of the fuel line tube under the influence of low temperatures is shown, and a method for studying the remains of the fuel line after exposure to the heat of a fire is proposed.

The relevance of monitoring and control of the mine environment during elimination of fires at the mining enterprises has been presented. The investigation results of the temperature field in the mine working of the coal mine in the vicinity of the seat of fire have been presented. It has been established that if the temperature behind the seat of fire does not depend much on the temperature diffusivity coefficient, then the length of the temperature «plume» before the seat of fire substantially depends on it. The dependence of the distribution of relative temperatures in front of and behind the seat of fire in the mine working of a coal mine has been presented. According to the proposed methodology it is possible to find the distribution of temperatures along the entire length of the mine working with a seat of fire. The further promising areas of theoretical and experimental studies of the unsteady distribution of fire gases along the length and cross section of the mine workings of coal mines during the accidents have been adduced.

The article describes the process of recreating the real physical environment of a dwelling and creating conditions for a fire as a result of an emergency fire hazardous operation of the electrical network and electrical equipment. The models of fire occurrence were created on the basis of practical experience in the study of real fires by specialists of the forensic institution of the FPS IPL in the Krasnoyarsk Territory, together with employees of the Main Directorate of the Ministry of Emergencies of Russia in the Krasnoyarsk Territory. The experiments carried out made it possible to reliably assess the incendiary ability of these fire hazardous phenomena, the peculiarities of the occurrence of combustion and the development of a fire due to them. The work carried out made it possible to create videos with the purpose of a visual demonstration to the population of how domestic fires can start and what consequences they can lead to. The videos were shown in early 2020 on television in the Krasnoyarsk Territory and were posted on the Internet on the popular video hosting «YouTube».

The article is devoted to the issues of self-heating of oiled fibrous and porous household materials at public catering facilities. The article shows the complexity of the investigation of the causes of fires occurred from spontaneous combustion of substances and materials during the fire and technical expertise. The article presents the results of the study of self-heating of oils of vegetable origin, previously deposited on the porous surface of household materials. Revealed that the self-ignition of vegetable oils are more prone to oils with an expired shelf life. Materials based on viscose with the addition of polyester fiber have the advantages to enhance the process of spontaneous combustion with respect to other household fibrous materials.

The article provides an overview of literary materials related to explosions and fires at the reprocessing plants and caused by the formation, accumulation and uncontrolled decomposition of traces of tributyl phosphate-based extractant (TBP). The reason for such explosions was the presence in the extractant of its decomposition products — dibutyl phosphoric and monobutyl phosphoric acids (DBP and MBP). To date, the effect of DBP and MBP on the flash and ignition temperatures of an extractant based on TBP has not been determined. The article presents the method of hydrolysis of TBP for accumulation of DBP and MBP in the extractant. The process of measuring the flash point temperature and ignition point temperature of a pure extractant and extractant with different contents of DBP and MBP is described. The dependence of changes the flash point temperature and ignition point temperature on the different contents of DBP and MBP in TBP is shown.

The article is devoted to increasing the efficiency of service activities using automated devices for the technical maintenance and repair of pressure head fire hoses. To reduce fatigue during repair work and increase the efficiency of maintenance, it is proposed to use a new prototype combined machine for maintenance and repair of fire pressure hoses. The main stages from the analytical review to the creation of a unique idea are considered. The authors structurally designed a new two-level mobile platform, which involves the placement of three technical modules: module turning fire hoses at the coupling head, module fold and roll sleeveless to the new edge module repair vulcanizer. The proposed design of the machine makes it unique and multifunctional.

Artificial intelligence technologies are actively introduced in various industries of the country, including in the field of fire safety of oil and gas complexes. Today, there are more than 110 million synthesized substances, and their fire hazard properties have been partially studied and only for a few thousand compounds. This creates difficulties in calculating the intensity of the thermal radiation of the flow for fire strait limit ketones. To solve the problem, we applied a method for predicting the fire hazard properties of oil products based on molecular descriptors and artificial neural networks. The specific mass burnup rate and the average surface density of the thermal radiation of the flame for a sample of substances were predicted, a comparative analysis was carried out. The relative error is determined, not exceeding 5%. Thus, using a digital approach to solving the problem of the lack of information on the properties of substances, we have expanded the existing database, which can be used to develop a fire safety system.

The mechanism of forming the resource needs of territorial fire departments is described. Various ways of assessing the level of fire danger of territories are analyzed. The factors influencing the state of resources of territorial fire protection units are studied. The analysis of the existing legal framework for the organization of fire fighting and emergency rescue operations. An approach is proposed in which for the optimal state of fire protection resources in order to neutralize the factors that generate fire danger, the number of main fire vehicles is dependent on the level of fire danger in the area of departure of the fire protection unit.
