Abstract |
: |
Electricity generation operations involve a wide range of occupational safety and health (OSH) hazards which lead to increased fatal and non-fatal injury rates. Therefore, electricity companies apply OSH management systems to reduce these rates. Risk assessment and management is one of the key elements in such management systems. The objective of the current study is to perform risk assessment in the isolated power plants (IPPs) of the Saudi Electricity Company (SEC). The risk assessment was conducted based on the five-star OSH management system using a combined hazard severity/ probability risk assessment matrix. Furthermore, a risk management model was developed to prioritize risk management plans using a hybrid approach of AHP-TOPSIS based on five criteria: (1) number of hazards, (2) cumulative risk rating, (3) number of extreme and high risks, (4) no of workers, and (5) no of 5-star elements. The results of the OSH risk assessment in the IPPs indicate that there is a variety of hazards in the IPPs, such as fire, electric hazards, physical and chemical hazards, and injury hazards. Most of the identified OSH hazards had high or medium risk levels, indicating the need for many action plans to control these hazards on the short or the long run. Because of the similarity of all IPPs, the results of the current study apply to all IPPs and, hence, the SEC may use them for planning OSH management in all IPPs. Based on the AHP-TOPSIS technique, the 16 common locations in IPPs were classified into 5 groups, according to their priority for risk management. The first group included the generators area and the control room as the most hazardous locations, followed by a second group containing the engine room and the fuel station, and a third group containing the mechanical and electrical workshops, and the diesel tank area. These locations had most of the hazards with moderate to high & extreme risk levels, and therefore, too many 5-star elements applied to them. The study recommends applying the proposed risk assessment and management model to IPPs and developing similar ones for operations with similar activities in the SEC. Additionally, further research on hazard control measures that eliminate or reduce the risks is recommended. |
