The number of accidents and deaths in the industry continues to increase. In this study, 30 occupational accidents in process industries between 2011 and 2021 were examined. This study proposes a customized Human Factor Analysis and Classification System for Process Industry to accommodate occupational accident investigation in the process industry.
