Question

flixborough disaster

Answer 1

The Flixborough explosion was the largest-ever peacetime explosion in the UK. There were 28 fatalities as well as the near complete destruction of the NYPRO plant in North Lincolnshire by blast and then fire. An official Court of Inquiry was established and charged with the responsibility of determining the cause(s) of the disaster and any lessons to be learnt. This paper reviews the disaster, its investigation and inquiry, its attributed cause, and an alternative possibility, and this redraws the lessons to be learnt for modern chemical plant design and accident investigation. The reanalysis suggests that the failure was caused by a complex two-step mechanism that resulted from the initial failure of only one bellows, a release of about 10–15 tonnes of cyclohexane, and the detonation of the consequent vapour cloud with an explosive effect of some 280 tonnes of TNT. This is compared with the single-step failure process reluctantly acknowledged by the Court; the amount of release accepted, 40–60 tonnes of cyclohexane, and its explosive effect, 6–16 tons of nitroglycerine. The results should be of interest to industry, regulators, and loss prevention and risk assessment specialists. hope it is useful and if you are satisfied with my answer then plz mark my answer as brainiest.... can u plz follow me......

Answer 2

The Flixborough disaster was an explosion at a chemical plantclose to the village of Flixborough, North Lincolnshire, Englandon Saturday, 1 June 1974. It killed 28 people and seriously injured 36 out of a total of 72 people on site at the time. The casualty figures could have been much higher, if the explosion had occurred on a weekday, when the main office area would have been occupied.[1][2] A contemporary campaigner on process safety wrote "the shock waves rattled the confidence of every chemical engineer in the country".[3][A]

The disaster involved (and may well have been caused by) a hasty modification. There was no on-site senior manager with mechanical engineering expertise (virtually all the plant management had chemical engineering qualifications); mechanical engineering issues with the modification were overlooked by the managers who approved it, nor was the severity of the potential consequences of its failure appreciated.

Flixborough led to a widespread public outcry over process safety. Together with the passage of the UK Health and Safety at Work Act in the same year, it led to (and is often quoted in justification of) a more systematic approach to process safety in UK process industries. UK government regulation of plant processing or storing large inventories of hazardous materials is currently under the Control of Major Accident Hazards Regulations 1999 (COMAH). In Europe, the Flixborough disaster and the Seveso disaster in 1974 led to development of the Seveso Directive in 1982 (currently Directive 2012/18/EUissued in 2012).
