Defining safety functions and safety barriers from fault and event trees analysis of major industrial hazards
The prevention of major accident hazard is the main objective of the SEVESO II directive. It relies notably on risk analysis and on the implementation of a safety management system. However, the methodology for risk analysis is not provided by the directive and different approaches are adopted within the European union. The objective of the European project ARAMIS is to build up a new integrated risk assessment method that will be used as a supportive tool to speed up the harmonized implementation of SEVESO II Directive. ARAMIS not only focuses on the identification and evaluation of the risk but also on the vulnerability of the environment by proposing tools to evaluate it and crosses this result with a spatial representation of the accident effect. A last innovative aspect of ARAMIS is to take explicitly the management into account by defining a management index which reduces or increases the global severity of the dreaded scenarios.
