Background & objectives: In total, 80% of accidents results from human errors. Preventing and reducing the number of accidents requires reduction in human errors. The most commonly used method for identifying human error is SHERPA (Systematic Human Error Reduction and Prediction Approach). The purpose of this study was to evaluate the human errors in tasks of a cement factory control room staffs using this technique.
Methods: In this case study research all tasks of "chief engineer", supervisor, and shift operator in the control room were studied. Hierarchical tasks analysis of tasks and sub-tasks was performed and then variety of errors was examined using SHERPA technique and their risk levels were determined.
Results: The findings from the HTA technique include 20 main task and 77 sub-tasks.
Generally, out of 155 errors detected by SHERPA, 49.68% was related to “Action error" which is the highest error type.
Conclusions: The studied risk levels showed that 72.9% errors related to "acceptable risk level without revision" and 16.13% to “unfavorable risk level”. In this study, the most important and prone to human error tasks were identified as “supervision on problem solving by supervisor", "removal of warning signs by operator" and "adoption of a methodology on abnormal situations by chief engineer".
Keywords: Control Room, Human Error, SHERPA.
