1. Introduction

This report tries to summarize the main aspects that characterize the hot debate about the risks of the LNG industry, which represents a very attractive energy entry point for the economies of the industrialized and developing countries. Unfortunately still a great divergence exists on the safety aspects between those who favour the new LNG plants and those who are scared by their impact: one of the most controversial points are the exclusion zones around such facilities in order to avoid the consequences of an uncontrolled release that can affect the people and the environment. This is often due to a poor understanding of the physical phenomena that may occur and to the intrinsic inaccuracies related to the model used for estimating such distances.
The intent of this report is to provide a better understanding of the
