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:
- Environmental analysis
- Human resources
- Dangerous products (both present in the structure or originated by the transformation/modification of the dangerous substances)
- Activities; infrastructures; plants and instruments
- Safety and security
- Consequences of the accident (overpressure waves; primary fragmentation; seismic waves; dangerous gasses; thermal radiations; iso-damage areas)
- Environmental damage (combustion; explosion; dispersion)
- Analysis of the surrounding environment
- Territorial compatibility of the deposit
- Precaution to prevent accidents (both on a project and organisation level)
- Critical situations; emergencies
- Containment systems
Furthermore; practical cases are discussed.
