On 21 September 2001, an explosion occurred at the AZF (French initialism for AZote Fertilisant, i.e. nitrogen fertiliser) fertiliser factory in Toulouse, France, belonging to the Grande Paroisse branch of the Total group.

Contents

Three hundred tonnes of ammonium nitrate was stored (the maximum capacity was 2,000 tonnes) in hangar 221 222. [1] The entire factory was destroyed, making a crater with a depth of about 7 metres (23 ft) and a diameter of 40 metres (130 ft). [2] Steel girders were found 3 kilometres (1.9 mi) away from the explosion site. [3] The blast measured 3.4 on the Richter scale, [4] with an estimated power equivalent to 20-40 tons of TNT. [2] The explosion was heard 80 km (50 miles) away. [5] Due to the acoustics of the hills and the loud sound, the explosion was reported as occurring in multiple places. Police at first believed that at least five bombs had simultaneously gone off. There is still controversy over the exact number of explosions[ according to whom? ].

The factory was close to the city: one of the most inhabited areas, Le Mirail, is 1 kilometre (0.62 mi) away. Around ten percent of the inhabitants of Toulouse had to be evacuated. [6]

Victims

The disaster caused 31 deaths, about 30 seriously wounded, and 2,500 light casualties. [7] Two thirds of the city's windows were shattered, causing 70 eye wounds.[ citation needed ] The total damages paid by insurance groups exceeded 1.5 billion euros.[ citation needed ]

Investigation

On 4 October 2001, France's then Environment Minister Yves Cochet announced that the explosion "may have been a terrorist attack" (the explosion occurred ten days after the September 11 attacks) and identified Hassan Jandoubi, a plant sub-contractor killed in the blast, as a person under investigation. French anti-terrorist authorities were prohibited by the Toulouse prosecutor from searching Jandoubi's house for five days after the incident. [8]

Police declared that Jandoubi had "possible Islamic fundamentalist sympathies", yet by the time the search was finally conducted, they said that Jandoubi's girlfriend had disposed of all traces of his clothes and photos. Authorities described the delay as damaging to the investigation. [9] [10] [11] [12]

In May 2006, the official investigation released a final report supporting a chemical accident theory in which sodium dichlorocyanurate mixed with 500 kg of ammonium nitrate spilled on the main nitrate pile 20 minutes before the explosion. [13]

<span class="mw-page-title-main">Dynamite</span> Explosive made using nitroglycerin

Dynamite is an explosive made of nitroglycerin, sorbents, and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867. It rapidly gained wide-scale use as a more robust alternative to the traditional black powder explosives. It allows the use of nitroglycerine's favorable explosive properties while greatly reducing its risk of accidental detonation.

<span class="mw-page-title-main">Nitroglycerin</span> Chemical compound

Nitroglycerin (NG), also known as trinitroglycerin (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester. Chemically, the substance is an organic nitrate compound rather than a nitro compound, but the traditional name is retained. Discovered in 1847 by Ascanio Sobrero, nitroglycerin has been used as an active ingredient in the manufacture of explosives, namely dynamite, and as such it is employed in the construction, demolition, and mining industries. It is combined with nitrocellulose to form double-based smokeless powder, which has been used as a propellant in artillery and firearms since the 1880s.

The 1947 Texas City disaster was an industrial accident that occurred on April 16, 1947, in the port of Texas City, Texas, United States, located in Galveston Bay. It was the deadliest industrial accident in U.S. history and one of history's largest non-nuclear explosions.

A chemical accident is the unintentional release of one or more hazardous chemicals, which could harm human health and the environment. Such events include fires, explosions, and release of toxic materials that may cause people illness, injury, or disability. Chemical accidents can be caused for example by natural disasters, human error, or deliberate acts for personal gain. Chemical accidents are generally understood to be industrial-scale ones, often with important offsite consequences. Unintended exposure to chemicals that occur at smaller work sites, as well as in private premises during everyday activities are usually not referred to as chemical accidents.

There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.

Hassan Jandoubi was a French national of Tunisian parents, who died on 21 September 2001, in the AZF chemical factory explosion in Toulouse in south-western France. He was subsequently investigated by French anti-terrorist authorities as the prime suspect in the blast. An official enquiry later determined the blast was accidental, and not a result of Jandoubi's actions.

Four workers at the plant were killed by the explosion, and eighteen others were injured. The seven-story building at the seat of the blast was completely destroyed, leaving only a crater, and significant damage was inflicted to the surrounding structures. Four nearby electricity generating stations were disabled by the explosion, and the effects of the blast were felt up to 30 miles away. A high-voltage line running adjacent to the plant and over the Missouri River was damaged, disrupting power in the neighboring state of Nebraska. Two 15,000-ton refrigerated ammonia storage tanks were ruptured, releasing liquid ammonia and ammonia vapors which forced the evacuation of 1,700 residents from the surrounding area.
