Modeling the major accident prevention legislation change process within Europe

The factors giving impulse to changing major accident prevention legislation within Europe, the so-called Seveso Directive, have not been thoroughly studied and molded into an understandable model thus far. For example the exact relationship between major industrial accidents and an ever changing legislation is still unexplored. This paper thoroughly investigates the parameters having influenced the change of the 1996 Seveso II Directive into the 2003 Seveso Directive Amendment 2003/105/EC and develops the accompanying legislation change process. The official major accident reports of Baia Mare, Enschede and Toulouse are studied in-depth, as well as many other official EU documents. Furthermore, experts from academia, government and industry who witnessed and/or participated into the legislation change process were interviewed in-depth. More profound insights into the societal debate following a major accident may help private companies to adapt their safety management system and their prevention policies, and may aid the legislator to develop more efficient and effective regulations. This way, the societal demand to change legislation in an ad hoc manner may be unpressurized.
