Abstract

The chemical industries have used large amounts of chemicals. If an accident occurs, it caused physical and human damage. We intended to investigate risk assessment for the prevention of accidents. The risk assessment by HAZOP technique has been applide to major chemical industries, and that result has been utilized efficiently. In this study, we analyzed Bow-Tie and HAZOP technique, and risk assesment was performed by Bow-Tie on toxic material process. As a result, the risk that can not be found in the risk assessment of the other is derived, and improvements of 14 to remove the dangers derived. Bow-Tie risk assessment is suitable to derive the applicability of risk factors in the field and to establish the improvement measures.

화학공장은 다량의 화학물질을 사용하기 때문에 사고가 발생하면, 많은 피해가 발생한다. 따라서 사고를 예방하기 위하여 위험성평가를 실시하고 있다. 화학공정은 HAZOP 기법을 이용하여 위험성평가를 실시하고 그 결과를 많이 활용하고 있다. 이 연구에서는 HAZOP 기법과 Bow-Tie 기법을 분석하고, Bow-Tie 위험성평가를 수행하였으며, 그 결과 다른 위험성평가에서 발견할 수 없었던 위험성이 도출되었고, 그 위험성을 제거하기 위한 14개의 개선사항이 도출되었다. Bow-Tie 위험성평가가 현장의 적용성과 위험요인을 도출하고 개선대책을 수립하는데 적합하다는 것을 확인하였다.
