Flixborough disaster By: Paradigma Carlo Giovanni. Picture taken 5 days after the Nypro Flixborough Disaster which happened on June 1, Pic by George Schofield, of Barrow-on-Humber. 1 June is the 40th anniversary of the Flixborough disaster, an explosion at a chemical plant sited on the banks of the River Trent in Lincolnshire.

They were introduced about 2 years ago, but Billingham managed for 45 years without them. With the passage of time these sentiments are diluted into bland reports about human error and everything being well under control — as happened with the Summerland fire.

This nitrate stress corrosion cracking was believed to have been due to the practice of spraying nitrate-treated cooling water as a means for diluting and dispersing small leaks. June 1,was a sultry afternoon, with people shopping in Scunthorpe town centre or enjoying themselves at the Appleby-Frodingham steelworks gala at Brumby Hall when catastrophe struck shortly before 5pm.

No drawing of the pipe was made, other than in chalk on the workshop floor. It took about ten years for their recommendations to be made and to come into force.

But just over six months later the hefty memorial, first positioned outside the new Nypro headquarters and then moved inwas gone — taken in an act of theft which caused further shock to the community. The disaster was caused by ‘a well designed and constructed plant’ undergoing a modification that destroyed its technical integrity.

It contained graphic information about the plant which gave us an invaluable insight into its construction.

The oxidation unit and neighboring units were destroyed and extensive damage was caused to the rest of the site. Each of the bellows had disintegrated into a few large pieces, all of which were found in the vicinity of the failed pipe. It was suggested that a diagram be made of the relation between the distance from the point of release and the size of the cloud tonnes of hydrocarbon equivalent at the plant containing materials that might explode.

Especially in plants that are treating hazardous materials, even relatively easy repairs or improvements of facilities should be made with thorough reference to the standards, and the design should be entrusted to professional engineers.


The occupants of the works laboratory had seen the release and evacuated the building before the release ignited; most survived. Abnormal pressures and liquor displacement resulting from this it was argued could have triggered failure of the inch bypass. No calculations were done to ascertain whether the bellows or pipe would withstand these strains; no reference was made to the relevant British Standard, or any other accepted standard; no reference was made to the designer’s guide issued by the manufacturers of the bellows; no drawing of the pipe was made, other than in chalk on the workshop floor; no pressure testing either of the pipe or the complete assembly was made before it was fitted.

This explosion killed 28 men were and injured 36 men on site. We were between editions and cleared flixbborough much space as we could to cover it. In area C, there should not be any low pressure tanks. Humberside Fire and Rescue Service Huge plumes of smoke seen across Scunthorpe as ‘severe fire’ tears through house Firefighters were called to Ashby High Street early on Sunday morning as residents of a house fled for their lives when a blaze tore through their home. It flidborough decided to remove the No.

However theoretical modelling suggested that the expansion of the bellows as a result of squirm would lead to a significant amount of work being done on them by the reactor contents, and there would be considerable shock loading on the bellows when they reached the end of their travel. However, the Court concluded that both phenomena occurred as a result of a sequence of improbabilities and coincidences.

As the New Scientist commented within a week of the disaster:. Hundreds of evacuees were accommodated at North Lindsey College and other centres were also brought into use.

Ten years after the tragedy the people of Flixborough stood in the churchyard and remembered the men who had been lost.

Retrieved 9 July Eighteen fatalities occurred in the Control Room as a result of the windows shattering and the roof collapsing. These images — credited to George Schofield, of Barrow-on-Humber — were brought in to Nostalgia last week by Raymond Ogg, whose home in Flixborough was one of many badly damaged by the blast.

Fires continued on-site for more than ten days. There had been no similar air leaks and consequently no similar water sprays on the other reactors. Property in the surrounding area was damaged to a varying degree.

Neither when they were first built, nor now that they are in operation, has any local or government agency exercised effective control over their safety. The Court could still be right that a single unsatisfactory modification caused the disaster but this is no reason for complacency. We believe that rules relevant to safety must be everyday working rules and be seen as an essential part of day-to-day work practice.


The cyclohexane oxidation process is still operated in much the same plant design in the Far East. Cast in bronzeit showed mallards alighting on water. Two months prior to the explosion, the number 5 reactor was discovered to be leaking. None of the flixbroough occupants of the plant control room survived, nor did any records of plant readings. No-one appreciated that the pressurised assembly would be subject to a turning moment imposing shear forces on the bellows for which they are not designed.

Nor flicborough anyone appreciate that the hydraulic thrust on the bellows some 38 tonnes at working pressure would tend to make the pipe buckle at the mitre joints.

Tests on replica bypass assemblies showed that bellows squirm could occur at pressures below the safety valve setting, but that squirm did not lead to a leak either from damage to the bellows or from damage to the pipe at the mitre welds until well above the safety valve setting.

No reference was made to the designer’s guide issued by the manufacturers of the bellows. The enquiry noted the existence of a small tear in a bellows fragment, and therefore considered the possibility of dusaster small leak from the bypass having led to an explosion bringing the bypass down. These requirements applied not only to changes to equipment, but also to process changes.

After fresh cyclohexane and recycle cyclohexane were scrubbed with water in a cooling scrubber, they were heated in a direct heat exchanger.

When lagging was stripped from it, a dixaster extending about 6 feet 1. A pipe was installed to bypass the leaking reactor so that the plant could continue disastet.
