The purpose of this study is to analyze which programs are suitable for field activities of firefighters in the event of chemical leakage by comparing the actual leakage range of silicon tetrachloride and the predicted damage impact range using a risk assessment program. Three risk assessment programs are used in the experiment: KORA and ALOHA, including CARIS, which firefighters currently use in case of chemical leakage. The researchers compared the damage impact range to see the difference between the predicted results from each program based on the program's process and weather condition data input and the actual scope of accident damage.
