Analysis of Cause of Excavator Safety Accidents according to the Accident Case Study

중대재해사례를 통한 굴삭기 안전사고 원인분석

In line with the construction projects, which have been increasingly getting larger and complex, safety accident has been on the rise, particularly those in association with the construction equipment. In a bid to prevent the safety accident, it's needed to analyze the cause of such accidents. The thesis was intended to identify the cause of safety accident by reviewing the cases of construction disaster complied by Korea Occupational Safety and Health Agency. The cases subject to study were limited to the accident by excavator. Summarizing the study is as follows. 1) Among the cause of accidents caused by excavator were, in order of high frequency, being caught in equipment or machine, falling, being crashed or bumped. 2) Among the causes of accident were, in order of high frequency, worker's unauthorized presence within the range of equipment operation. inappropriate use, failure of equipment inspection prior to starting work and inappropriate work method. The study is highly expected to pave the foundation for further study as well as to make commitment to mitigating the safety accident.

최근 건설업의 대형화, 복잡화됨에 따라 안전사고가 증가하고 있다. 특히, 건설장비에 의한 사고 발생수가 증가하고 있다. 이런 사고의 예방을 위해서는 발생원인을 분석할 필요가 있다. 본 논문은 한국산업안전공단의 건설재해사례를 통해 안전사고 원인을 분석한다. 연구의 범위는 굴삭기 장비로 한정하였다. 본 연구의 결과를 요약하면 다음과 같다. 1) 굴삭기 재해 발생 형태는 협착${\cdot}$감김, 낙하${\cdot}$비래, 충돌${\cdot}$접촉 순으로 분석되었따. 2) 재해원인은 작업반경 내에 근로자출입, 주용도 이외의 용도로 사용함, 작업시작 전 저멈불량${\cdot}$ 작업방법불량 순으로 분석되었다. 이 연구결과는 차후 연구의 기초를 정립하고, 안전사고를 줄이는 기대효과를 가질 것이다.
