✦ Synopsis

Outil de SImulation des RISques (OSIRIS) is a hazard simulation tool for the training of firemen or manufacturers during interventions with dangerous raw material transportation. This software allows one to obtain a quick answer regarding areas touched by the accident and to provide assistance for judicious decision taking as well as to define the means to implement and the time of reaction to realise an efficient intervention. OSIRIS simulates different types of accident like calculation of leak flow, calculation of evaporation flow, simulation of toxic gas dispersion, confining, simulation of explosions, simulation of fires. Three types of result are obtained: numerical values, graphs of evolution according to distance, effect distances drawn on a map of the accident site.

In the second part of the publication, a simulation of a toxic gas dispersion accident is realised. OSIRIS is a decision-taking help tool which allows a simple use and a reduced calculation time, and that is able to simulate many cases of technological accidents.
