Abstract

This study examined the factors influencing safety scores in air conditioning installation projects, with a specific focus on the characteristics of safety managers and project-specific details. Given the increase in industrial accidents within this sector and the lack of research on smaller-scale operations, this analysis of 7,046 safety data records from Company A aimed to address this gap. The results indicate that the month of project commencement has the most significant impact on safety scores(correlation coefficient of 0.21), followed by the age of the safety manager(correlation coefficient of 0.06). Interestingly, the educational background of the managers did not appear to influence safety outcomes. Furthermore, project cost was found to have a negative correlation with safety scores(-0.1), suggesting that lower-cost projects may be associated with higher risk levels. These findings underscore the importance of developing tailored safety checklists that take into account the specific timing and scale of air conditioning installation projects. Additionally, the results suggest that incorporating both experienced(older) and less experienced(younger) safety managers into safety strategies may be beneficial for achieving optimal safety outcomes. This balanced approach could leverage the strengths of both groups, potentially enhancing overall risk assessment and mitigation efforts.

안전관리자는 체크리스트를 기반으로 자신의 경험, 지식, 및 프로젝트의 특성을 종합하여 작업 환경의 위험을 평가한다. 이러한 방법은 안전관리자 간의 위험 인식의 차이를 가져올 수 있다. 에어컨 시공 분야에서의 산업재해가 증가하고 있음에도 불구하고, 대부분의 연구가 대규모 프로젝트에 집중되어 있어, 에어컨 시공 분야의 특수한 안전관리 요구 사항을 충족시키는 체크리스트 개발에 한계가 있다. 이에 본 연구는 에어컨 설치 공사에 종사하는 안전관리자들의 개인적 특성(연령, 전공)과 공사 관련 요소(공사 비용, 착수 시기)가 체크리스트에 따른 안전 점수에 미치는 영향을 분석하고자 한다. A사로부터 수집한 7,046건의 안전 점수 데이터의 분석 결과, 프로젝트의 착수 시기가 안전 점수에 가장 큰 영향을 미쳤으며(0.21), 안전관리자의 연령 역시 제한적으로 영향을 미치는 것으로 나타났다(0.06). 그러나, 안전관리자의 전공은 점수에 영향을 주지 않았으며, 프로젝트의 공사 비용은 안전 점수와 음의 관계(-0.1)를 보였다. 이 연구는 프로젝트의 규모와 시기를 고려한 맞춤형 안전 작업 체크리스트 개발의 필요성과 다양한 연령의 안전관리자를 균형있게 배치하는 전략의 중요성을 강조한다.
