Analyzing the cause of human electrical accidents using Swiss Cheese model

Purpose This study aims to explore the factors influencing electrical accidents. Here, the authors aim to understand and model the causes of electrical accidents at multiple levels. Design/methodology/approach In the study, the authors have tried to put causes of accidents in the electricity distribution segment, in the framework of the Swiss Cheese model. Delphi kind of expert survey was conducted to find the Cheese Slice (level) and the causes (holes) for electrical accidents. Inputs from a hundred experts having more than five years of experience in electrical utility companies have been used to find Cheese Slice and holes, to explain the occurrence of an electrical accident. Findings Effective training for safe work practices, safe knowledge and closer supervision would go a long way to plug the holes in the Cheese Slice in human factors. The difference in perception of managers, supervisors and workers on the importance of various causes of electrical accidents are also presented and discussed. Research limitations/implications This research is based on expert opinion and survey where respondent perception is reported. Actual accident data has not been used here. Practical implications The holes or causes of accidents at different levels (Cheese Slice) have been identified for plugging or removal for better safety. Social implications Electrical energy is widely used, and therefore, electrical safety is a social concern and also improving it is a social need. Originality/value The study contributes to electrical safety issues in the electrical utility sector.
