Abstract :

Background and Objective: Increased rate of chemicals production and their consumption in various industrial processes are consiederd as characteristics of an industrial community. Improper management and incorrect use of them will cause accidents and harmful damage to human health and the environment. Method: In this paper, considering the safety and health risks and the environmental aspects associated with storage, preservation and working with chemicals produced in sugar factory, these chemicals were identified by Walking & Talking Through method. Then, the multi-criteria decision-making methods such as AHP, TOPSIS and Eigenvector technique were used for analyzing the risks of the identified chemicals. Finally, the chemicals were divided into three categories in terms of risk by determining the median in SPSS. Findings: The results of calculating the risk of the chemicals used in sugar factory show that ethyl alcohol with weight of 0.646, ammonia with weight of 0.566 and caustic soda with weight of 0.558 are the most important chemicals affecting the safety, health and environment of the factory and the surrounding area. Accordingly, the strategies to control and reduce the risks of chemicals were identified. Discussion and Conclusion: In this study, introducing a multi-criteria method for calculating the risk factor, the highest number of features inducing the risk of a substance to the personnel is used in the calculation.
