AZF plant explosion (Toulouse, 2001)

Toulouse, September 21, 2001, 10:17 a.m.: Building 221 at the AZF plant run by Grande Paroisse, a TotalFinaElf subsidiary, explodes. It held several hundred metric tons of off-spec ammonium nitrate, production rejects awaiting recycling. The crater measures several tens of meters across. 31 dead, several thousand injured, and damage across much of the city: homes, schools, the Gallieni high school, the Marchant psychiatric hospital. The bill comes close to 2 billion euros. For insurers, AZF is first a matter of volume. Tens of thousands of claims arrive within a few weeks, for windows, doors and roofs, often under modest homeowners' policies, sometimes with no policy at all. The market organizes itself to move fast: simplified procedures for small claims, payment by the victim's own insurer without waiting for liability to be settled, then recovery against Grande Paroisse. The group chose not to contest civil compensation and paid, without waiting for the criminal case. Victims with no insurance, or beyond their policy, turned to it directly. The criminal case lasted eighteen years: acquittal in 2009 for lack of firm proof of the cause, conviction on appeal in 2012, reversal by the Cour de cassation in 2015. The Paris Court of Appeal convicted again in 2017, and the Cour de cassation upheld that ruling in December 2019. Lawmakers drew the lesson in the law of July 30, 2003, which created the state of technological disaster and technological risk prevention plans. For a claims manager, the file remains the reference for an urban mass loss of industrial origin. Not to be confused with the 2020 Beirut port explosion, another ammonium nitrate case, stored there outside any industrial framework, in a country where home insurance remained rare.
