  1. Industrial risk: main issues (Scira Menoni, Politecnico di Milano)

  2. A relevant problem of planning is that everything has to be done so quickly .… My experience is that the overall time of design and implementation is shorter if there is enough time to think to the entire project (M. Andersson, Swedish Railway Adm.)

  3. Accidents menacing people, houses, infrastructures Contamination of neighborhoods, rural areas… Groundwater contamination/toxic release Air pollution/toxic cloud

  4. Chemical risk Contamination * Delayed * Long term effects * Chronic/degenerative effects Severe accident * Sudden * Acute effects * Explosion/fires/release * Accident during hazmat transportation

  5. Contamination risk: epidemiological studies Exposure and vulnerability * Exposure factors * Individual susceptibility (cancerogenic markers) Hazard * Toxic substances * Context conditions must be considered: geological, metereological…

  6. Reference legislation in the EU • Seveso Directive II: 96/82/CEE 2. Seveso Directive III: 2003/105/EC 3. D.lgs 334/1999 eD.lgs 238/2005 4. DM 151, 9/5/2001

  7. Seveso Directive II: 96/82/CEE e DGL 334/1999; Seveso Directive III: 2003/105/EC e Dlgs 238/2005 • Safety management and policy in the firm • Control over land uses • Right to be informed • External emergency plan

  8. Classification of plants * Plants subject to safety report * Plants subject to notification only

  9. Probabilistic risk analysis R= H* V*E Scenarios: choosing a specific event and its characteristics Difference between probabilistic risk analysis and scenario approach Vulnerabity Hazard Risk

  10. P1 P2 P3 A way to bring scenario approaches closer to probabilistic risk assessment (PRA)

  11. Hazard analysis: - probability of each scenario; - Analysis of types of failures in the plant - Chain of failures

  12. Vulnerability assessment: • Other plants (domino effects); • lifelines (domino effects); • transportation networks;

  13. Vulnerability assessment: • - Public buildings; • - Dwellings; • - Population

  14. Differences between Seveso I and II • Seveso I • Need to make hazardous installations safer (inspection, technical devices) • Internal emergency plan • Citizens’ right to know • Seveso II Seveso 1 + • Safety policy in the plant • Focus from inside to outside: • Domino effects; • Land use planning • External emergencyplants

  15. and: hazmat transportation. A future directive?

  16. And last but not least: brownfield cleaning up (DM 447/1999)
