Abstract

The European Directive 96/82/EC; “Seveso II”; required companies to quantify the impact caused by a major accident. However; due to new knowledge about dangerous substances and because of severe accidents involving dangerous products (Baia Mare; Romania and Donana; Estonia); it was felt necessary to improve the Seveso II legislation.

Through the Directive; 2003/105/EC; more detailed plans were introduced as well as information needed to assess the potential damage caused by major accidents involving explosives. In fact; the new directive proposes a drastic reduction of the quantities of dangerous substances allowed; new and more detailed information both on the structure and on the surrounding areas and more specific and focused controls by competent authorities.

In this article; algorithms and procedures are given to asses danger; risk and total impact after 5 years of practice and confrontation with fire departments and local environmental authorities. The procedure is presented through the following categories:

  1. Environmental analysis
  2. Human resources
  3. Dangerous products (both present in the structure or originated by the transformation/modification of the dangerous substances)
  4. Activities; infrastructures; plants and instruments
  5. Safety and security
  6. Consequences of the accident (overpressure waves; primary fragmentation; seismic waves; dangerous gasses; thermal radiations; iso-damage areas)
  7. Environmental damage (combustion; explosion; dispersion)
  8. Analysis of the surrounding environment
  9. Territorial compatibility of the deposit
  10. Precaution to prevent accidents (both on a project and organisation level)
  11. Critical situations; emergencies
  12. Containment systems
  13. Insurance

Furthermore; practical cases are discussed.
