Fire Risk Analysis of Petrochemical Plant Facilities through Fire Modeling

In this study, fire case analysis and fire type and risk analysis were conducted for each process according to the ISO 17776 checklist to determine the firefighting activities and worker evacuation areas in case of a fire in a petrochemical plant. Therefore, fire modeling was performed for storage tanks with the largest fire load according to the wind speed and combustibles in order to analyze the radiant heat and smoke behavior. The effects of radiant heat and smoke were increasingly high in the order of n-heptane, gasoline, and diesel. Moreover, the firefighting activities and worker evacuation areas varied greatly depending on the wind speed rather than combustibles. However, because the results of the study cannot exclude the possible dependence on the fire modeling, it is necessary to generalize and standardize the results of the study by accumulating data through various scenarios.
