PREDICTION OF RISK IN DEPENDENCE FROM DISEASE AND WORKING CONDITIONS OF EMPLOYEES WHICH EMPLOYED IN EXTRACTION OF IRON ORE

Abstract

Introduction: The assessment and management of occupational risks has the purpose conducting of analysis and assessing the health of workers by timely, complete and adequate passing of the previous and periodic medical examination, registration and analysis of morbidity and establishment of cause-and-effect relationship with working conditions. The aim:Prediction of occupational risk based on study of diseases with temporary disability was conducted in the analysis of disability sheets and the report on causes of temporary disability in workers extraction of iron ore. Materials and methods: Hygienic, epidemiological and statistical methods of research were used to solve this purpose. Results: In the workers involved in the extraction and processing of iron ore the level of morbidity with temporary disability is from 81,87±3,64 to 98,06±2,49 cases (p<0,05), from 806,53±40,51 to 1217,67±63,50 days of disability (p<0,05), the average duration of one case was from 10,00±1,42 to 12,39±0,24, and according to the scale of assessment of the indicators of morbidity rates by L. E. Notkin characterized in days as average; in cases as high. The calculation of morbidity rates (L and OR) makes it possible to predict what degree and class of harmful production factors can lead to the corresponding levels of morbidity. The proposed forecasting method makes it possible to predict the categories of occupational risk in depending on the class of working conditions and the relative risk of morbidity with temporary disability. Conclusions: Studying the morbidity and condition of working conditions is the basis for predicting occupational risk for effective management decisions.
