The Feyzin disaster occurred in a refinery near the town of Feyzin, 10 kilometres (6 miles) south of Lyon, France), on 4 January 1966. An LPG spill occurred when an operator was draining water from a 1,200m³ pressurised propane tank. The resultant cloud of propane vapour spread, until it was ignited by a car on an adjoining road. The pool of propane in the bund caused the storage tank to be engulfed in flames, which produced a Boiling Liquid Expanding Vapour Explosion (BLEVE) when the tank ruptured. This resulted in a fireball which killed and injured firemen and spectators. Flying missiles broke the legs of an adjacent sphere which later BLEVE'd. Three further spheres toppled due to the collapse of support legs which were not adequately fire protected. These vessels ruptured but did not explode. A number of petrol and crude oil tanks also caught fire. The conflagration took 48 hours to bring under control. This incident resulted in the deaths of 18 people, the injury of 81 and extensive damage to the site. == Prior to the incident == The Feyzin refinery (run by Elf, now acquired by Total), employed around 250 personnel at the time of the incident and had a processing capacity of about 2 million tons of crude oil annually (40,000 barrels per day, approximately). The main refinery units were located to the north of a local road. The main storage areas were situated to the south of this road in a 145m wide strip adjacent to a boundary fence with a motorway. This was the area in which the disaster occurred. The equipment in this area consisted of: * Four 1,200m3 spherical vessels used for propane storage * Four 2,000m3 pressure vessels used for propane storage * Two 150m3 horizontal bullet pressure vessels used for propane and butane * Ten 2,500m3 and 6500m3 floating roof tanks used for the storage of finished grade petrol and kerosene The LPG (liquefied petroleum gas) storage spheres were about 450m away from the nearest refinery unit and about 300 m (1,000 feet) from the nearest houses in the village. The shortest distance between an LPG sphere and the motorway was 42.4m (138'), and the spacings between individual spheres varied from 11.3m (37') to 17.2m (56'). Each of the spheres were provided with fixed watersprays both at the top and at the mid-height, plus an additional single spray directed towards the bottom connections. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Feyzin disaster」の詳細全文を読む スポンサード リンク
