Hygienic evaluation covered work conditions of main occupations in ferroalloys production on a plant in Ural regions. The occupations are: ferroalloy furnace operator, ferroalloy furnace worker and crane operator. The findings proved that the workers are exposed to a complex of occupational hazards among which dust and unfavorable microclimate play major role. At the enterprise, occupational dust disease cases (silicosis from exposure to silicon-containing dust) are registered, with average development duration of 28.7 +/- 6.2 years.
