2 Accidental Risk Assessment Methodology for IndustrieS in the framework of SEVESO II directive General Presentation of the Project O. SALVI Direction des Risques Accidentels Institut National de l Environnement Industriel et des Risques Parc Technologique Alata, BP 2 - F Verneuil-en-Halatte, France telephone : , fax : ,

3 EC Work Programme extract 5 th 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.

4 CONTENTS Context and objectives Work description The Consortium, Review Team & collaborations

5 Major Accident Hazard Assessment in the context of Seveso II UNIT AUNIT B How to assess … the major accident hazards ? the prevention management effectiveness ? + PPAM + SMS + Technical Safety You cannot manage if you cannot measure NEED OF INDICATORS

6 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

7 A R A M I S The Methodology Major Accident Hazards Reference Accident Scenarios Industrial UNIT

8 Major Accident Hazards A. Algorithm for Major Accident Hazards identication based on industrial equipement combined to hazardous substances (67/548 CE) B. Review of safety devices commonly used (norms, regulation, state of the art...) using the bow tie approach WP 1 : Scenario identification

9 Critical Event (LOC,…) Initiating Event Undesirable Event Current Event Sec. Critical Event Dangerous Phenomena Major Events Bow Tie Approach

10 WP 1 : Scenario identification Reference Accident Scenarios State of the art in policies conception operation and control mitigation Lessons learnt from accidents Industrial UNIT Major Accident Hazards Algorithm

11 Major Accident Hazards A. Algorithm for Major Accident Hazards identication based on industrial equipement combined to hazardous substances (67/548 CE) B. Review of safety devices commonly used (norms, regulation, state of the art...) Lessons learnt C. Lessons learnt from accidents and analysis of the most common Causes Reference Accident Scenarios D. Definition of Reference Accident Scenarios Using risk analysis methods (HAZOP, Preliminairy Hazards and Consequences Analysis, FMEA...) Taking into account some safety barriers WP 1 : Scenario identification
