The Flixborough disaster was an explosion at Nypro chemical plant close to the village of Flixborough (near Scunthorpe), Humberside formally Lindsey, Lincolnshire (now North Lincolnshire), England, on 1 June 1974. It killed 28 people and seriously injured 36. At 16:53 on Saturday 1 June 1974, the temporary bypass pipe (containing cyclohexane at 150°C (302°F) and 1 MPa (10 Bar)) ruptured, possibly as a result of a fire on a nearby 8 inch (20 cm) pipe which had been burning for nearly an hour. Within a minute, about 40 tonnes of the plant's 400 tonne store of cyclohexane leaked from the pipe and formed a vapour cloud 100200 metres (320-650 feet) in diameter. The cloud, on coming in contact with an ignition source (probably a furnace at a nearby hydrogen production plant) exploded, completely destroying the plant. Around 1,800 buildings within a mile radius of the site were damaged.
The fuel-air explosion was estimated to be equivalent to 15 tonnes of TNT (60 gigajoules) and it killed all 18 employees in the nearby control room. Nine other site workers were killed, and a delivery driver died of a heart attack in his cab.
Observers have said that had the explosion occurred on a weekday, more than 500 plant employees would likely have been killed. Resulting fires raged in the area for over 10 days. It was Britain's biggest ever peacetime explosion until the Buncefield Depot explosion in 2005.
Substantial destruction of property was recorded in Flixborough itself, as well as in the neighbouring villages of Burton-upon-Stather and Amcotts. Significant structural damage affected Scunthorpe (eight miles away) and the blast was heard (and felt) twenty-five miles away in Grimsby.
Although the area was quite remote, graphic images of the disaster were soon shown on television due to BBC and Yorkshire Television film crews who had been covering the Appleby-Frodingham Gala in Scunthorpe that afternoon.
