Application of Geographical Information System for Toxic Release from Chemical Process Industry
Abstract:
Pathumthani is one of the most important industrial areas in Thailand. Almost factories are color and insecticide
factories which use hazardous chemicals such as VOC (volatile organic compound), arsenic, DDT (dichloro-diphenyl
-trichloroethane), and hydrogen cyanide. One critical consideration is the release of these hazardous chemicals during
transportation and storage. To estimate the toxic release boundaries and concentration and to generate emergency plan
and response, a chemical dispersion model and a geographical information system (GIS) were applied.
ALOHA; the chemical dispersion model simulator, is used to study the toxic threat zone. In this work, there are three
cases with different sources of release. The color factory is the first case released toluene. The second and the third cases
are the pesticide factories that release hydrogen cyanide. All toxic threat zones are imported into the affected area map
of ArcView GIS 9.1. The results showed that the released chemicals (toluene and hydrogen cyanide) covered villages,
schools, hospitals, factory around the release source and roads. The implementation of these two software can provide
the routes for the best evacuation and the nearest facilities (police men, fire extinguish men, hospital car etc.). These routes
use less travel time than the limitation time of ERPG.
