Hazardous industrial sites have always represented a threat for urban settlements.

Abstract
Hazardous industrial sites have always represented a threat for urban settlements. A tank explosion or an accidental emission of dangerous substances often provoke damages that overcome the borders of industrial sites and affect the surrounding areas. If the industrial sites are located in natural hazard prone areas, “damage chains” could happen too, as in Turkey, during the 1999 Kocaeli industrial region earthquake. In Italy, the Directive 96/82/EC “Seveso II” and Ministerial Decree 9/5/2001 “Essential requirements in matter of regional and urban planning” provide to land use planners a procedure for evaluating the compatibility between land uses and dangerous industrial plants. This procedure does not represent an effective tool to evaluate the links among natural hazards and technological hazards and does not allow us to describe the real world phenomena continuity and complexity. Furthermore, the procedure is based on a quantitative threshold system which does not provide accurate information to decision makers. In order to face the main weaknesses of the current methodologies for technological risk assessment and to move towards a na-tech risk assessment, this paper provides a multi attribute decision making method joined with fuzzy set theory based techniques. In detail, multi attribute ranking method has been applied to deal with factors related both to natural and major accident risks and the fuzzy approach allow us to deal with quantitative and qualitative variables and to overcome the deterministic methods commonly used to assess compatibility of dangerous industrial establishments with urban settlements. Using a GIS application, the method has been tested on a middle size Municipality in the Campania Region, classified as 2nd class seismic area (Ordinance 3274/2003) and affected by the presence, within the city core, of a LPG storage plant, classified as dangerous by the Seveso II Directive (art. 9).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
