초록

건설 현장의 소규모 굴착현장은 10m 미만의 굴착공사로 주로 전담 안전관리자가 없어 안전관리가 어려운 한계가 있다. 해당 연구의 목적은 소규모 굴착현장에서 작업자 스스로 안전관리를 수행할 수 있는 사고사례 기반의 체크리스트를 개발하는 것이다. 사고사례는 Construction Safety Management Integrated Information(CSI) 시스템에서 최근 5년간 발생한 사고 데이터를 획득하였으며, 이를 기반으로 사고 발생원인, 형태 및 기인물(Contributing Factors) 등을 분석하였다. 분석된 원인은 체크리스트 개별 항목과 연계될 수 있도록 고려하여 새로운 체크리스트를 개발하였으며 작업 전과 작업 중으로 구분하여 총 14개의 항목으로 구성된다. 설정된 14개 항목이 합리적으로 구성되었는지 전문가 그룹을 통한 설문 조사로 각 항목의 쌍대 비교(Pairwise comparison)를 수행하였으며, 비교 결과 모든 항목이 소규모 굴착현장 안전관리에 필수적으로 요구되는 것으로 나타났다. 또한 새롭게 발생한 사고사례를 기반으로 개발된 체크리스트의 신뢰성을 검증하였으며, 모든 사고사례가 체크리스트 항목과 연계되는 것도 확인하였다. 해당 연구에서 제안한 체크리스트는 소규모 굴착현장에서 실질적이고 효과적인 사고 예방에 기여할 수 있을 것으로 판단된다.

Small-scale excavation sites in construction-defined as those involving excavation projects less than 10 meters deep-often lack dedicated safety managers, creating challenges in safety management. This study aims to develop an accident case-based checklist that enables workers to manage safety independently at these sites. Accident data from the past five years were obtained from the Construction Safety Management Integrated Information system, and the causes, types, and contributing factors of accidents were analyzed based on this data. These analyzed causes were linked to specific checklist items, resulting in a new checklist comprising 14 items divided into pre-construction and during-construction phases. To ensure the logical structuring of these 14 items, a group of experts conducted a survey employing pairwise comparisons. The results indicated that all items are essential for safety management at small-scale excavation sites. Furthermore, the reliability of the developed checklist was validated using newly occurring accident cases, confirming that each accident was associated with the checklist items. The checklist proposed in this study is expected to contribute to practical and effective accident prevention in small-scale excavation sites.
