Abstract

Introduction: Undoubtedly, the first step in controlling accidents is to analyze them to identify the root causes. In this study, the root causes of accidents leading to severe consequences have been analyzed using the beta tripod technique in Lian Oil Company.

Materials and Methods: The research method is descriptive-analytical. In this research, the events of 2020 in two barrel-making and barrel filling units of Lian Oil Refining and Trade Company have been investigated. The tripod-beta method is one of the methods of tracing the roots of accidents, which is widely used in the oil industry because of its special attitude towards the element of human error. Using investigator software, a tripod beta diagram related to three fracture and disability accidents was drawn and after recording and identifying the relevant causes and obstacles, corrective measures were taken to prevent similar accidents. The basis of accident control is the creation of appropriate control and defense systems in such a way as to prevent the interconnection and interaction of the risk factor and the target factor.

Results: The results of this study show that non-compliance with safety principles due to reduced staff awareness and lack of long-term and short-term training are the root causes of accidents studied and had the highest impact on these events. 45% of cases were related to the cause of the accident. Other cases after training have had almost the same effect on the occurrence of events. Each of the cases accounted for 11% of the causes of the accidents.

Conclusion: Beta tripod technique is currently one of the best methods for tracing the roots of accidents. The results also indicate that effective measures in the normal time phase, i.e. employing more talented people, conducting training at the beginning of employment, and upstream perspective, i.e. operator coordination with hardware and methods of implementation in the phase of ideas and thinking and design will greatly prevent accidents.
