RESUMEN
There were performed biochemical and cytological studies of blood in healthy workers of chrysotile asbestos plant in order to determine the functional state of the body, depending on the length of service and working conditions. Mentioned differences between the functional state of the organism were determined in the longitudinal study, under construction on schedule time series with the test group at specified intervals (every year for 7 years surveyed, the same group of healthy workers). The differences between the indices allow one to discriminate different levels of the functional state of the organism for the workers employed at processing complex with experience of 4 and 5 years, and for the employees in the mining and transport workshop with the experience of 5 and 6 years. As a result the work experience of 5 years is considered to be an occupational hazard for workers at processing complex, and 6 years of experience - as an occupational hazard for workers of mining and transport workshop.

Studies of allowable (safe) length of service in occuptions of mining transport enterprise "Kostanaiskie mineral" JSC were conducted to forecast occurrence of dust lung diseases in workers exposed to chrysotile-asbestos dust. To calculate allowable length of service, the authors used values of average shift concentration of chrysotile-asbestos dust. Based on the calculated data of the allowable length of service in chrysotile-asbestos production, the authors forecasted course of dust lung diseases.
