The Risk Assessment is an important legal requirement which should be carried out in industries in order to prevent any incident in future and manage emergencies better. In this article a typical LPG (Liquefied Petroleum Gas) storage bullet of capacity 14.7m3 and truck tanker of capacity 18 m3 were selected for the study. Risk assessment was carried out for various fire scenarios such as BLEVE, VCE, and Jet fire which can happen in LPG storage area. The inputs used in the estimation are collected from various articles and from a typical LPG handling and storing industry in the southern part of Tamil Nadu. The meteorological conditions for the assumed Madurai region are given as an input data in the ALOHA software for dispersion predictions of various scenarios. The accident situations are selected from various reports and literatures of LPG storages around the world. By using the ALOHA software, the dispersion models are used to estimate dispersion concentrations, Blast effects, Flammable effects, Thermal radiation and Toxic effects. The results are arrived from the predicted and user defined inputs in ALOHA software with the references and industrial investigations.
