  Abstract

An analysis of worldwide incidents in chemical plants found multiple root causes and the lack of preventive measures was catastrophic. Therefore, the main objective of this study was to determine the factors contributing to and main predictive indicators for catastrophic incidents, such as fires and explosions, in the chemical plants. In this study, 94 accidents, including the incident investigation data reported by Chemical Safety Board for catastrophic incidents and recent domestic incidents at chemical plants, were reviewed. Common contributing factors were identified, and frequency analysis was conducted. Moreover, bow tie analysis was applied to determine the prevention and mitigation measures for each catastrophic incident. Accordingly, common contributing factors behind 16 categories of catastrophic incidents were derived and analyzed, and leading indicator candidates were presented in three priority groups. Presumably, the leading indicator can be used to determine what to prioritize in preventing catastrophic incidents in chemical plants.
