초록

화학공장의 협력업체 사고는 기술적, 관리적 문제점 외에도 원청과 협력업체 간의 관계에서 발생하는 문제점과 같은 사회구조적인 문제점이 원인으로 작용할 수 있다. 이에 본 연구에서는 화학공장에서 협력업체가 정비보수작업 중 발생한 화학사고의 원인을 사회기술시스템의 통합적 측면에서 분석하고 사고원인요소 간의 연결 관계를 파악하고자 하였다. 최근 5년간 국내의 공정안전관리 대상 사업장에서 협력업체가 정비보수작업을 수행하던 중 발생한 화학사고 21건을 분석 대상으로 선정하였다. AcciMap을 이용하여 계층별 사고원인요소를 파악하였고, 업무처리절차를 이용한 분석을 통해 각 업무단계에서의 사고원인요소를 분석하였다. 분석 결과 화학공장 협력업체 사고는 단순히 관리적, 기술적, 인적인 문제뿐만 아니라 간헐적으로 수행하는 정비보수작업이라는 특성과 원청과 협력업체라는 관계에서 발생하는 구조적인 문제점이 복합적으로 작용한 결과인 것으로 나타났다. 따라서, 협력업체의 사고를 예방하기 위해서는 사회적인 측면과 기술적인 측면을 모두 고려하여 사고원인을 분석하고 예방대책을 마련할 필요가 있다.

Accidents involving subcontractors at chemical plants can be caused by not only technical and managerial issues but also socio-structural problems, such as those arising from the relationship between the company and the subcontractor(s). Therefore, this study aims to analyze the causes of chemical accidents that occurred during maintenance and repair work by subcontractors at chemical plants from an holistic socio-technical systems perspective and to identify the relationships between accident causal factors. Twenty-one accidents that occurred at domestic process safety management companies during maintenance and repair work over the past five years were analyzed. AcciMap was utilized to identify causal factors at each hierarchical level, and an procedure-based analysis was conducted to examine causal factors in each work stage. As a result, it was found that chemical plant subcontractor accidents were the result of complex interactions of not only management, technical, and human factors, but also structural problems that occurred due to the characteristics of maintenance and repair work that is performed intermittently and the relationship between the company and subcontractors. Therefore, in order to prevent subcontractor accidents, it is necessary to analyze accident causes and establish countermeasures considering both social and technical aspects.
