With the growth of the chemical industry, the types and amounts of chemical substances used have steadily increased, process conditions have become more complex, and operating processes have become harsher. Although management measures to prevent accidents are proposed through regulations, in the industrial field, awareness and information are insufficient to require technical and academic support, and there is insufficient prior data that can be referred to for risk assessment and follow-up management for the processes and materials used in this study. Therefore, in this study, risk assessment techniques were applied to the process of manufacturing urethane foam using 4,4’-Diphenylmethane diisocyanate(MDI) and Toluene diisocyanate(TDI) mixtures to convey the concept of risk management through the process of deriving results and create data that is easily accessible from an engineering standpoint. The entire process in which the study material is transported was divided into four zones, and accident scenarios for escape were analyzed and risk levels were calculated through qualitative risk assessment(HAZOP). In addition, the initial initiating event and occurrence frequency corresponding to the accident scenario were identified through semi-quantitative risk assessment(LOPA), and the reduction rate(PFD) for passive/active mitigation measures(IPL) was applied and compared with the risk tolerance standard. Quantitative risk assessment(CA) was conducted for scenarios that did not meet risk tolerance standards. The ALOHA program was used to predict the diffusion distance in the event of a toxic substance leak.
