인적요인을 중심으로 한 위험요인 도출 방법론에 관한 연구

Abstract

Human factor is one of the major causes to the accidents. A lot of risk identification techniques have been developed for prevention of accidents. Nevertheless, most of them were interested on physical factors, because quantitative evaluation of human factors was difficult quantitatively. According to lack of risk identification techniques about human factors, most of industrial risk assessment for human factors were based on data of accident analysis. In order to develop an effective countermeasure to remove or reduce the risk caused by human factors, a systematic analysis is needed. This study aimed to develop a risk identification technique focused on human factors that could mainly be applied to industrial fields. In this study, Ergo-HAZOP and Comprehensive Human Error Analysis Technique were used for developing the risk identification technique. In the proposed risk identification technique, Ergo-HAZOP was used for broad-brush risk identification. And more critical risks were analysed by Comprehensive Human Error Analysis Technique. In order to verify applicability, the proposed risk identification technique was applied to the work of pile head cutting and coping work. As a consequence, extensive hazards were identified and fundamental countermeasures were established. It is expected that much attention would be paid to prevent accidents by human factors in industrial fields since safety personnel can easily find out hazards of human factors if utilizing the proposed risk identification technique.
