Application of GIS for the Control of Major Accident Hazards

The presented study discusses the importance of GIS in assessing fire and explosion modelling involved major accident hazards. simulation toxic dispersions atmosphere is especially dangerous for densely inhabited areas, or close to sensitive environment, which are called target systems. Therefore, mathematical-physical predictions from hazard programs such as Areal Locations Hazardous Atmospheres (ALOHA) have be combined with a Geographic Information System (GIS) ArcGIS.
