The article is devoted to a review of the available scientific approaches to assess the role of hazardous factors of physical and chemical nature, which are very important for the management of occupational risks of workers in dust-hazardous industries using the example of welders. General approaches and models for assessing the risk to public health in general are presented quite fully, the mechanisms of the effect of dust particles on the development of occupational pathologies in welders, including toxic and carcinogenic ones, have been studied in depth, a number of articles are devoted to the study of the effect of a thermal (physical) factor of a chronic nature. The above studies are of a scattered nature, the combined effect of physical and chemical factors are not taken into account, based on the S. Arrhenius equation, which is especially important in the closed spaces of the working area. There is no comprehensive methodology for assessing health risks for workers in dust-hazardous industries and welders. The development of the above-mentioned comprehensive methodology for assessing health risk of workers in dust-hazardous industries based on taking into account hazardous factors of physical and chemical nature is very promising in the near future.
