Metallurgy is exposed to a complex of production factors, the levels of which often exceed the hygienic standards. Working conditions are characterized by grade 3 (harmful) 2-4 degrees, which determine the level of occupational morbidity (PZ). The PP indicator at ferrous metallurgy plants in recent years has fluctuated from 11.9 to 20.2 cases per 10,000 employees that have passed their MEP. In the structure of PZ 59.5% of cases are respiratory diseases. A trend has been established in these enterprises to increase deaths in the workplace, mainly from diseases of the cardiovascular system.
