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. The results of the work can be used in the design of electrostatic precipitators, taking into account the local properties of the captured dusts, their composition, dispersion, and performance of the installed ventilation system. Also, the results of experimental use can be used in the development of methodological recommendations aimed at determining the optimal operation modes of electrostatic precipitators, instructions for their safe operation
