Taiwan EPA is in charge of toxic substance disaster prevention and response work. Thus, it is intended to develop a methodology that can analyze the potential risk in an area in order to help the emergency response system and local operating facilities to have a better understanding of the potential risk, and better prepared in case of emergency. This project aimed at risk potential analysis for toxic substance disasters. The final report is submitted in December 2008. The project has completed the following works: 1. Select routes with high frequency of transporting toxic substances to perform risk potential analysis and risk degree assessment. (1) Collect the toxic transporting forms submitted to EPA to find the statistics data for transporting routes, type of substances, transporting quantities, frequency of transportation. (2) Analyze the characteristics of the toxic transporting data to find five representative substances and perform consequence analysis. 2. Final local parameters for dispersion modeling. Draw the risk potential map. Apply the toxic transporting data to perform the risk potential for routes with high frequency and large quantity of transporting toxic substances. The routes are digitalized and an area risk potential map is drawn, the degree of risk are marked. 3. Complete the risk potential analysis for transporting toxic substances for one demonstration county. From the risk potential map, potential area for hot zone and cold zone can be drawn. The routes for response and evacuation can also be drawn. The possible locations for emergency response center and shelter locations can also be identified in the map. 4. Provide the risk potential analysis results for application by county environmental bureau and disaster rescue supporting units. From the risk potential map, it is possible to assess adequacy of the manpower and available equipment in county environmental bureau and disaster rescue supporting units 5. Provide training and technology transfer Provide continuing, regular training courses to county environmental bureau and disaster rescue supporting units for exchange of experiences and technology development. This will help to reinforce the optimization of response route selection, and allocation of resources. Overall, the response efficiency can be improved and losses from a disaster can be reduced.
