The Impact of Safety Programs on Accident Indicators in a combined cycle power plant

Background: The effectiveness of safety systems is critical to the realization of their goals. Thereششfore, this study was conducted to investigate the role of safety management systems on accidents and the status of safety performance indicators in a combined cycle power plant in 2011. Materials and Methods: This descriptive-analytical research was carried out in two stages in all Yazd Combined Cycle Power Plant units on accident victims in a period of 8 years (2004-2011). The AFR, ASR, and FSI indices were derived from the OSHA standard using the formulas and data obtained from the questionnaire and interviews with the people. The sampling method was also the census. Results: The total number of accidents was 287 cases in the 8-year period (2004-2011). The results showed, there was a significant relationship between age and work experience, as well as between age and marital status. The main causes of accidents were unsafe acts. The lowest level of personal protective equipment was used in 2004 (15.2%) and the highest rate was in 2011 (30%). After the implementation of the IMS, the trend of accident indicators in the years was decreasing with regard to the washing time. Also, the amount of AFR, ASR and FSI indices of the accident in terms of work shift in 2004 compared to the years after implementation has decreased substantially. Conclusion: Safety and health management systems is an appropriate tool for reducing accident rates and accident indicators might also a good way of monitoring the safety performance and safety and health management systems. Background: Nowadays, safety management plans have an effective role in reducing the incidence of accidents. Therefore, this study was conducted to investigate the role of safety management systems on accidents and the status of safety performance indicators in a combined cycle power plant in 2011. Materials and Methods: This descriptive-analytical research was carried out in two stages in all Yazd Combined Cycle Power Plant units on accident victims in a period of 8 years (2004-2011), according to the documentation of previous years. The Accident Frequency Rate (AFR), Accident Severity Rate (ASR), and Frequency Severity Rate (FSI) indices were derived from the OSHA standard using the formulas and data obtained from the questionnaire and interviews with the people. The sampling method was also the census. Results: The total number of accidents was 287 cases in the 8-year period (2004-2011). The results showed, there was a significant relationship between age and work experience, as well as between age and marital status. The main causes of accidents were unsafe acts. The lowest level of personal protective equipment was used in 2004 (15.2%) and the highest rate was in 2011 (30%). After the implementation of the Integrated Management Systems (IMS), the trend of accident indicators in the years was decreasing with regard to the washing time. Also, the amount of AFR, ASR and FSI indices of the accident in terms of work shift in 2004 compared to the years after implementation has decreased substantially. Conclusion: According to the results, due to the positive impact of safety programs (IMS), incident indicators have a downward trend and unsafe acts have decreased.
