In the aim to prevent and manage major accidents on an industrial site, many methodologies and directives have been developed. But, in France no formalised methodology has been proposed to competent authorities to determine a risk level of an industrial site. A first work of methodologies' synthesis permitted to propose some basis of a new methodology. This one will be based on the industrial site, the environment and the safety management. To reach this aim, four indexes are developed; the first one concerning the hazard source (the establishment), the second one the flux (the vector of propagation of accident considering the specific environment), the third one the vulnerability of targets (human, environmental or equipment), and finally the fourth one concerning the safety management (prevention and protection actions). This new approach will provide a cartography of risk level for an industrial site and its vicinity to bring a decision help for risk managers and competent authorities.
