Analysis of health and safety risks of Abadan gas power plant in operation phase using TOPSIS technique

Precise identification of the risks of power plants as a part of a comprehensive safety analysis is recommended by monitoring organizations. Assessment and risk management techniques in industrial activities through the use of preventive approach to identify hazards, assess and control safety - health risks unit is studied. In this study, risks and effects of Abadan gas power plant were studied and investigated In this study after assessment of different units of power plant from view point of safety-health issues, different kinds of risks in utilization operation phase, a questionnaire was prepared in Delphi technique and was handed to 99 elite and power industry experts and for the analysis of the safety-health risks of Abadan gas power, methods of multiple criteria decision making, e.g.; TOPSIS and eigenvector and Entropy was used. For this purpose, after prioritizing risks of each unit separately using TOPSIS, using one-way ANOVA test, the most priority risks of Abadan gas power plant were determined. Results calculated from the Abadan gas power plant risk show that the risks of MV panels weighting 0/879,work with power keys weighting 0/783 and work with transformations weighting 0/760 in electric unit were known of the most important health and safety risks of the power plant. More solutions to control and reduce the identified risks were presented. Some of these solutions are: using protective and electricity interruption equipment's and developing a safe working condition with safe treatments. Also in order to prevent, control, and decrease damage to the power plant personnel; it was suggested to use self-protection tools and also to choose and maintain devices correctly. At last, to do audit and self-inspection, along with minimizing bad direct and indirect health-safety consequences of Abadan gas power plant, presenting management plans and continuous health-safety was mentioned, and the most important cases of them included: measurement of thermal stress, light, amount of noise, vibration and interval examination of all the needed locations in the power plant.
