Abstract
ABSTRACTThis research was conducted to assess health, safety, and environmental risks of a gas power plant in southern Iran. In order to identify the subject risks of the power plant at operational phase a questionnaire was designed using the Delphi method. The questionnaires were put at the disposal of 99 electricity industry experts. Risk assessment was done using multicriteria decision-making methods such as technique for order of preference by similarity to ideal solution (TOPSIS), entropy, and Eigenvector technique. Following prioritization of risks at each power plant unit, top-priority risks were determined by one-way ANOVA. The obtained results indicated that the risk of working with medium voltage boards with a weight of 0.879 at the power plant's Electricity Unit is the most important safety and health risk in the studied power plant while risk of servicing the unit with fuel of gas weighting 0.807 and delivery of gas fuel with weight of 0.630 in the Exploiting Unit and work on liquid fuel clutch with weight of 0.603 in the Mechanical Unit are the most important environmental risks in the gas power plant. In conclusion, this study concludes that health, safety, and environmental risk assessment can be a structured and used as a systematic approach to plan for environmental protection and personnel health.
