다양한 사고분석 기법을 활용한 컨베이어 끼임사고 심층분석

Abstract

Objective: The aim of this study is to show that it is effective to use of a set of different and appropriate accident analysis methods for comprehensive accident analysis. Background: When an accident happens, investigation and analysis of the accident can be conducted for various purposes. The most important purpose among them is to prevent any similar accident by analyzing the root causes, and consequently establishing and implementing preventative measures. To achieve it, the identification and elimination of the fundamental causes of the accident rather than superficial causes should be emphasized. In reality, however, there is a tendency to conduct only perfunctory investigation and analysis due to the limited time and technology. Method: In this study, several official accident analysis methods with different strengths and areas of application were used as a set, and the stuck-in-the-conveyor belt accident was analyzed in depth. The accident analysis methods used in this study were 'Events & Causal Factors Charting and Analysis', 'Barrier Analysis', 'Change Analysis', 'Root Cause Analysis', and 'SINTEF models for accident cause analysis'. Also, the method of 'analysis of major events at each stage of the facility life cycle' was presented and applied in the study as a new additional analysis method for systematic analysis. Results: By using a set of accident analysis methods, we were able to analyze the cause of the accident systematically and in-depth. Conclusion: Accident investigation and analysis using appropriate investigation methods contribute more effectively and objectively to derive causal factors, such as contributing factors and root causes. Application: It may be used as a suitable technique for investigating and analyzing accidents at workplaces and accident investigation agencies.
