| dc.description.abstract | This study conducts an in-depth analysis of hydrofluoric acid (HF) tanker leakage accidents during transportation in the Taoyuan area and explores corresponding response strategies. The research methods include a literature review, field investigations, and risk scenario simulations combined with local wind direction and meteorological data. The study employs the ALOHA toxic dispersion model to simulate the hazard range of a potential HF tanker accident on National Highway No. 1 and calculates overlapping hazard areas and risk values. GIS software is used to visualize population risk values for each village in graphical form, serving as a basis for emergency response and drills.
The simulation results show that under Scenario 1 (based on the 5-year average wind speed), population risk values range from 2,400 to 120,000 people/km2. Under Scenario 2 (based on the 5-year maximum wind speed), the risk values range from 2,333 to 110,000 people/km2. In Scenario 3 (with a lower leakage volume), the risk values range from 1,400 to 14,000 people/km2. Higher risk values are observed in Taoyuan, Zhongli, Luzhu , and Yangmei. The hazard range is significantly influenced by variables such as wind speed, wind direction, leakage volume, atmospheric stability, and temperature, which affect the dispersion outcomes.
The study concludes with recommendations to conduct practical drills in high-risk areas and provide chemical knowledge training to residents to enhance emergency response capabilities. Expanding the scope of the study could improve the accuracy of the results. Additionally, integrating emergency response resources is essential for enhancing disaster response speed. | en_US |
