To identify reference scenarios with some safety devices some safety management

To build up a risk level index integrating consequence severity evaluation management effectiveness evaluation environment vulnerability evaluation

To share experience & propose an harmonised approach in risk assessmentin the context of Seveso II

CONCLUSION

A method to assess the major accident hazards based on the evaluation of the consequences

Evaluation of the management efficiency : technical and organisational aspects,to reach the goals of the directive

Evaluation of the environment sensitivity :useful for land-use planning / emergency plans

3 independant indexes for comparability : help for decision making and management

Harmonisation : a hard challenge
