Abstract: “Safety is seen as a key factor for a successful business and an inherent element of business performance.

It is also necessary to face the risks and accidents that can occur. In this paper, the aim is to present ontology for risk assessment in industrial case to feed a case based reasoning data base in order to evaluate risks and then regulate human behavior and the system parameters.”
