Brussels, 28/09/2001 (Agence Europe) - In a letter addressed to the President of the European Commission, Romano Prodi, French Communists Sylviane Ainardi and Francis Wurtz note that the explosion at the AZF plant (classified "Seveso") in Toulouse on 21 September had caused immense human and material damage: over 30 dead, over 2,400 injured, 20,000 private and social housing damaged, teaching establishments, hospitals and shops out of service. "We propose drawing lessons from this serious accident by engaging in a review process of the 1982 and 1996 Seveso Directives and lead to a tightening of security standards and the respect of the environment, as well as new more binding rules for the location of plants", the two MEPs write.
