5th EC Framework Programme EESD Energy, Environment and Sustainable Development, Part A
EESD RTD activities of a generic nature
(i) The Fight against Major Natural and Technological Hazards
I.2. Technological Hazards
I.2.2. Risk assessment and forecasting. Development of innovative approaches for risk assessment and forecasting technologies. Aspects of integration of hazards in confined spaces or resulting from transport systems; information and early warning systems; interactions between technological hazards and city structures, living / working practices.
I.2.3. Risk mitigation and management. The development of low risk, low environmental impact technologies and practices, risk mitigation, integrated decision making support systems and information and emergency management.

UNIT B
How to assess … the major accident hazards ? the prevention management effectiveness ?
You cannot manage if you cannot measure NEED OF INDICATORS

5. ARAMIS Objectives 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 assessment in the context of Seveso II

30. 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
