The paper describes the ARIPAR project aimed at the assessment of the major accident risks connected with storage, process and transportation of dangerous substances in the densely populated Ravenna area in Italy, which includes a large complex of chemical and petrochemical plants and minor industries, essentially distributed around an important commercial port. The project started by making a complete inventory of fixed installations and transportation activities capable of provoking major fire, explosion and toxic release events; Relevant accident scenarios were then developed for the single hazard sources; probabilities were assigned to the events and consequences were evaluated. Finally iso-risk contours and F-N diagrams were evaluated both for the single sources and for the overall area. The methodological approach and the results have proved to be very useful for the priority-ranking of risk mitigating interventions and physical planning in a complex area.
