What caused the Seveso disaster?
Abstract—The accident which occurred during the production of TCP at Seveso. Italy, was possibly caused by an unforeseeable exothermic reaction with increase of temperature, slow decomposition of the reaction mass, formation of gas and rise in pressure.
What happened Seveso?
In July 1976, a chemical plant explosion near Seveso, Italy exposed locals to the highest known levels of 2,3,7,8-tetracholorodibenzo-p-dioxin (TCDD or dioxin) exposure to a residential population (Mocarelli 2001; Pesatori and Bertazzi 2012).
What was the purpose of the Seveso Directive?
Its primary objectives were to prevent major accidents involving dangerous substances and limit the possible consequences of such accidents for human health and the environment. Subsequent incidents led to amendments to the Seveso Directive, and Seveso II (Directive 96/82/EC) was eventually adopted on 9 December 1996.
Why is differentiation no longer made in Seveso 2?
In the Seveso II Directive, differentiation for storage and process of dangerous substances is no longer made. This change is explained by the fact that the application of the Directive is based upon the potential to create a major accident, which is supposed to be identical for the same quantity of dangerous substance wherever it occurs.
What was the difference between Seveso 1 and 2?
Whilst Seveso I targeted specific activities and included a list of dangerous substances, Seveso II introduced a classification system for dangerous substances (toxic, flammable/explosive, and dangerous for the environment) and specified threshold quantities for certain types, categories and group of categories of such substances.
What was the final change introduced by Seveso III?
A final major change introduced by Seveso III is enhanced public participation. Governments are obliged to actively inform the public on a permanent basis about both upper-tier and lower-tier Seveso establishments and guidelines in the event of an accident.
