The article presents an analysis of the modern state of fire resistance of building structures. Special attention is paid to the directions of improvement of methods of fire resistance of building structures, buildings and structures. The special value of the actual fire resistance of the building enclosing structures in providing fire protection of the object is shown.

The work is devoted to the issues of the efficiency of using electrical filtering and dust removal equipment at fire and explosion hazardous objects of high content of dust and combustible fibers, for example of the Krasnoyarsk feed mill. The article presents the results of the pilot application of an electrostatic precipitator in the ventilation system of a feed mill, proving the possibility of its safe use and a high degree of dusty air purification, which will significantly reduce the risk of primary and secondary dust explosions. Also, the article  provides a description of the device of the proposed electrostatic precipitator, which allows for the process of dust removal in fire-hazardous premises, characterized by an increased concentration of organic fine dust in the air.

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.
