Abstract: (1049 Views)
Introduction: About 60 to 90 percent of an accident in the industry is caused by human error. This study aimed to assess the effectiveness of safety procedures in reducing human error in Yazd Combined Cycle Power Plant employees.
Materials and Methods: The present study is a quasi-experimental intervention that was conducted aimed to measure the human error of 121 employees of Yazd Combined Cycle Power Plant in 5 occupational groups (safety and firefighting, generator operation, generator operation, chemical refinery, warehouse keeping, and generator repair) in 2020. First, job safety analysis (JSA) was performed. Safety procedures related to each job were prepared, and with the help of their items and observing the process of doing work, the percentage of human error before and after the investigation was calculated. The data were analyzed using descriptive statistical indicators including mean, standard deviation, median, interquartile range, frequency and frequency percentage, and Wilcoxon nonparametric test by SPSS software version 24. The significance level was considered 0.05.
Results: A study on five main jobs, according to Wilcoxon test results showed, the highest and lowest human error percent before the intervention was related to generator repair occupational groups (58.59%) and warehouse keeping (4.16%). A significant difference was between human error percent before (433.41 ± 35.14) and after (440.21 ± 29.29) the intervention (p <0.001).
Conclusion: This study showed that performing job safety analysis and implementing safety procedures related to each job will decrease people's human error percent. Therefore, the implementation of safety procedures related to each job was suggested to the industry. This procedure must be obtained by careful job analysis, and an appropriate procedure should be developed using a panel of experts.
