Abstract

In order to prevent industrial accidents, this study presented a methodology to ensure that risk aggravating factors are reflected in risk assessments at manufacturing sites and demonstrated it by applying it to actual manufacturing sites. As a result of a statistical analysis of all 242,906 accidents that occurred in the manufacturing industry over the past 10 years, new workers less than 6 months old, foreign workers, older workers over 55 years old, and jobs where hands and arms are exposed to risk areas, Non-routine work performed from 9 o'clock to 12 o'clock showed a significantly high accident rate. In addition, a weighted value was applied to estimate the possibility of an accident at the risk determination stage through focus group interviews. Through the results of this study, risk weighting factors can be quantitatively reflected in risk assessment, which is meaningful in preventing accidents by evaluating the size of the identified risk closer.

본 연구는 산업재해를 예방하기 위하여 제조업 현장에서 위험성평가 시 위험 가중요인이 반영될 수 있도록 방법론을 제시하고 실제 제조업 사업장에 적용하여 실증하였다. 제조업에서 최근 10년간(2012~2021) 발생한 사고 242,906건 전체에 대하여 사례를 통계적으로 분석한 결과 6개월 미만의 신규 작업자, 외국인 작업자, 55세 이상의 고령 작업자 및 손과 팔이 위험구역에 노출되는 작업, 9시에서 12시 전까지 실시되는 비일상 작업은 유의성 있게 사고발생률이 높게 나타났다. 또한 표적집단면접(FGI)을 통하여 위험성 결정 단계에서 사고의 가능성 추정에 가중 값으로 적용하도록 하였다. 본 연구결과를 통하여 위험성평가 시 위험 가중요인을 정량적으로 반영할 수 있고 파악된 위험의 크기를 보다 근접하게 평가함으로써 사고를 예방하는데 그 의의가 있다.
