A significant spread of the problem of dust and gas contamination of the working area air at the enterprises of the mineral resource complex, a high degree of risk of acquiring occupational diseases by employees performing work in unfavorable conditions. Purpose and objectives of the study: The purpose of the work is to normalize the working conditions of the staff of LLC "Shakhtinskaya Keramika". Tasks: 1. Analysis of technological and organizational factors that lead to the formation of dust. 2. Assessment of the state of the air environment by the dust factor. 3. Selection of measures aimed at minimizing the impact of the dust factor. Subject and object of research: The object of the study is the workplaces of electric and gas welders at LLC "Shakhtinskaya Keramika". The subject of the study is the dust situation at LLC "Shakhtinskaya Keramika" and ventilation equipment designed to reduce dust and gas pollution in the air of the working area of the electric and gas welder. Theoretical and methodological basis: A systematic, comprehensive, cyclical approach to the study of the aspiration process, as well as the choice of effective measures to improve the equipment and the process of capturing dust particles from the air of the working area. Scientific novelty of the work: The dependence of the durability of the filter material of the bag filter on the physical and chemical properties of the fibers of this material is proposed.
