ABSTRACT

According to the recent statistics on chemical accidents, 72 cases resulted from transport vehicles and 14 of those cases spilled hydrochloric acid, the most frequently spilled chemical from the accidents. A small leakage occurred in most of the chemical accidents, but the massive spill occurred due to the vehicle rollover. When hydrochloric acid reacts with fire water or rain after leakage, extremely toxic gases such as hydrogen chloride are generated and spread into the atmosphere, causing severe damage. Since responding to vehicle accident is relatively more difficult, it is important to take preventive measures to reduce the risks considering the worst-case scenario such as the rollover. Therefore, this study used ALOHA to compare the end points of ERPG for the rollover accident between the existing vehicle model and an improved one, which confirmed that the improved vehicle could reduce the end points by an average of about 33.3 to 40%.
