Except a few petrochemical industrial zones, majority industrial zones in Taiwan do not carry out risk potential assessment for chemicals they are dealing with prior to their setup. Although some government divisions in Taiwan have started analyzing risk potential of toxic chemicals for presently existing industrial zones, little evaluation or investigation has done for industrial zones that are under the planning or pre-development stage. This study selected an area at Wuchi, Taichung that has not yet been developed into an industrial zone, and then designed this area into a simulating industrial zone. Chemical risk potential simulation was conducted based on local climate data. The acquired information was then submitted into the geographic information software (GIS) to calculate the possible range of area that may be influenced. The result suggested that the risk potential zone of toxic gas diffusion is greater than that of fire and heat radiation. Risk potential zone with a stable wind speed is greater than the one with a wind speed of the yearly average. Toxic gas diffusion and fire and heat radiation risk potential areas are both affected by wind direction. As the quantity of chemicals increases, so is the range of the risk potential zone. Therefore, to control the risk potential zone, one method is to limit the quantity of chemicals used in the industrial zone, while the other method is to develop low-toxicity and low-hazard manufacturing processes or chemical for replacing those toxic ones. These measures can effectively curb the size of risk potential zones, thereby reducing their impacts on the neighboring areas.
