Introduction. The assessment of the development of work-related and occupational diseases is a base for adoption of decisions on management of occupational risks and it should be directed at development of safe work conditions and prevention of occupational diseases.
Purpose of the study. Occupational risk assessment of disorders in the health status of workers at the leading metallurgical enterprise.
Materials and methods. In order to establish cause and effect relation between development of morbidity of workers and harmful factors of the work environment there have been calculated the following indices; morbidity rates per 1000 workers ®, relative risk (RR), relative risk for individuals who have been exposed to harmful exposure in absolute figures (ARe) and in % ( AR %), relative risk for the population in general in absolute figures (RAR) and in % (PAR %) among workers of the blastfurnace, open-hearth and agglomeration shops.
Results. When assessing a relative risk it was established that workers of the open-hearth department were at the most risk in occurrence of diseases among the examined shops – RR 3,04, CI 95 % (2,83–3,26); the relative risk rate for workers of the blast furnace was also significant and made RR 2,27, CI 95 % (22,07–2,48) and RR 2,0, CI 95 % (1,77–2,09), respectively. As a result of assessment of the risk of disorders on the health of workers of agglomeration shop it is established the highest risk rates were recorded for disease of eyes and their appendixes, muscular-skeletal system, infectious and parasitic diseases, urogenital and respiration system diseases. When assessing the risk of disorders in the health status of workers of the blastfurnace shop it was established that the highest risk rates were recorded in the following nosological types: diseases of the eye and its appendixes, diseases of the skin and subcutaneous tissues, infectious and parasitic diseases, diseases of the muscularskeletal and urogenital systems.The risk health assessment in workers of the open-hearth shop showed that the highest risk rates were recorded for diseases if the ear, skin, eye, infectious and parasitic diseases as well as diseases of urogenital and muscular-skeletal systems, digestive system and respiratory apparatus. A part of diseases, caused y the effect of harmful work conditions according to all diseases in workers of the examined shops (SR,%) exceeded such rates for the population in general (RAR,%), thus proving the effect of harmful work conditions on the workers, health.
Conclusion. The rate of occupational risk in workers of the leading enterprise of the iron-and-steel industry by rates of temporary morbidity in all examined shops can be referred to the category “high” occupation risk. The assessment of occupational risks by the data of the temporary morbidity in the examined shops pointy to a high degree of its occupation relation and require conduction of direct preventive measures.
