摘要：Conduct field investigation and engineering analysis of a plastics processing and manufacturing enterprise in an industrial park according to the characteristics of chemical industry, to pick out the typical toxic substances, e.g. noise and dust. Adopt the fuzzy comprehensive risk evaluation method to evaluate the occupational health risk level of this enterprise. Utilize the concentration grading of occupational health hazards to determine the weights of indicators at each grade, use the ratio of exposed workers to determine the weight coefficient, and calculate according to the principle of maximum membership degree to determine that the occupational health risk is Grade I, which represents the negligible risks. As judged based on the numerical values assigned for the descriptive grade set, determine the result of the comprehensive evaluation of enterprise working environment and occupational health risk as Grade II, which represents the "Good, Low risk". As compared with other methods often used at present for evaluating the occupational hazards, the results from the fuzzy comprehensive evaluation can better deal with the fuzzy characteristics of occupational hazard evaluation in addition to the realization of comprehensive evaluation on multiple hazards, more objective and realistic as using fuzzy vectors to replace exact point values in the evaluation results.
