Human Errors Assessment for Board Man in a Control Room of Petrochemical Industrial Companies using the extended CREAM

One of the important characteristic features of modern industries is the precise control of key components of the industry through central control rooms. Thus, committing an error by the control room staff can be catastrophic. The present study was conducted with the aim of identifying and evaluating human errors in the control room of one of the petrochemical industries.
The present descriptive-analytic study was conducted in a control room of one of the petrochemical industries. In this research, the job tasks in the main control room were first analyzed using hierarchical analysis. Then, using the extensive CREAM method, in addition to identifying human errors, probabilistic user controls and cognitive probability errors for job tasks were determined and evaluated. All stages of this research were conducted ethically.
The results of the study showed that the type of control style for the Board man tasks was strategic in 88% of the cases and the remaining 12% was of the instant type. Based on the results of the CREAM method, execution errors (55%), interpretation errors (20%), planning errors (14.9%) and observational errors (10.1%) were respectively the most determined errors.
Regarding the determination of the role of the most important factors in the implementation of tasks, the review and redevelopment of the program of shift work and optimization of the communication system were among the most important suggestions of the present study.
