Today, increment of population and technology development cause to increase many pollutions in human societies which have many effects on human health situation. Thus, it is necessary to pay attention coherent planning to reduce risk. Use of methods for evaluation of riskis an important instrument to control health risks. This research is performed to discuss status of health risks of Larestan factory. For this reason, fuzzy Topsis method was used which firstly, four health risks insights including (safety insight, safety performance, comprehend risk and evaluate risk) were discussed. According to results of estimation for Topsis fuzzy, threshold value for risk evaluation was estimated as 0.86, 0.726. The most suitable transmission variable is determined as risk evaluation, in other side; it was suitable pattern for risk transmission evaluation (t) for mild regression with LFUZZY TOPSIS. The findings help managers of occupations in order to reduce health potential risks and provide new insights to solve uncertain in management and control potential risks.
