fatalilities due to Human factors

That night club fire is just awful.

We had a Fire Officer doing a training course, and he had that video, But he gave the warning that parts are "really very very upsetting", (He wasn't wrong), and he would only show it to a select few that requested it.

2 people left because they felt faint.

Here's a link to the news story:

Many thanks to you all for your excellent contributions - I really appreciate this.

Hi Chris

The Bradford City Fire in 1985 is an example of how the 'human factor' led to many more people dying as a result of not taking the situaton seriously enough, coupled with inadequate exits (some padlocked) and evacuation procedures:

Hi Chris,

A few examples of high profile disasters that had human factors as their root cause;

• Three Mile Island nuclear power plant release
• Chernobyl
• Kegworth M1 air crash
• Tenerife airport disaster
• USS Vincennes – warship mistakenly destroys airliner

Sure you could Google these – hope they help.

Chris,
I would choose Flixborough as one of your presentations.
You have plenty of information.
Julian, to the 96 - You'll Never Walk Alone.

The chemical plant, owned by Nypro (UK) (a joint venture between Dutch State Mines and the British National Coal Board), and in operation since 1967, produced caprolactam, a precursor chemical used in the manufacture of nylon. Residents of the village of Flixborough were not keen to have such a large industrial development so close to their homes and had expressed concern when the plant was first proposed.

The process involved oxidation of cyclohexane with air in a series of six reactors to produce a mixture of cyclohexanol and cyclohexanone. Two months prior to the explosion, a crack was discovered in the number 5 reactor. It was decided to install a temporary 50 cm (20 inch) diameter pipe to bypass the leaking reactor to allow continued operation of the plant while repairs were made.

[edit] The disaster
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 100–200 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, house windows visibly shook) over thirty-five miles away in the city of Kingston Upon Hull on the north bank of the river Humber.

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.

[edit] Consequences
The official inquiry into the accident determined that the bypass pipe had failed due to unforeseen lateral stresses in the pipe during a pressure surge. The bypass had been designed by engineers who were not experienced in high-pressure pipework, no plans or calculations had been produced, the pipe was not pressure-tested, and was mounted on temporary scaffolding poles that allowed the pipe to twist under pressure. It should be noted that the by-pass pipe was a smaller diameter (20") than the reactor flanges (24") and in order to align the flanges, short sections of steel bellows were added at each end of the by-pass - under pressure such bellows tend to squirm or twist. These shortcomings led to a widespread public outcry over industrial plant safety, and significant tightening of the UK government's regulations covering hazardous industrial processes. See COMAH Regulations.

Despite protests from the local community the plant was re-built but, due to a subsequent collapse in the price of nylon, it closed down a few years later. The site was demolished in 1981 although the administration block still remains. The site today is home to the Flixborough Industrial Estate, occupied by various businesses and Glanford Power Station.

The foundations of properties severely damaged by the blast and subsequently demolished can be found on land between the estate and the village, on the route known as Stather Road. A memorial to those who died was erected in front of offices at the rebuilt site in 1977. Cast in bronze, it showed a number of mallards in flight landing on water: When the plant was closed the statue was moved to the pond at the parish church in Flixborough. During the early hours of New Year's Day 1984 the sculpture was stolen. It has never been recovered and those responsible for the crime have never been found.

The plinth it stood on, featuring a plaque listing all those who died that day, can still be found outside the church.

[edit] New theories on the causes of the disaster
In April 2007 new evidence was presented by Dr John Cox at a one-day symposium at University College London. Dr Cox argued there were two explosions, a smaller one, which was overlooked, happening before the massive blast. [1] An eyewitness backed the claims and explained how she had tried to contact the police but the incident was never followed up. [2] Dr Cox criticised the Health and Safety Executive (HSE) for "[coming] up with the safe conclusion to allay public fears, rather than a significant conclusion which is that it was quite a complex issue".[3]

Previously, in April 2000, allegations of cover-up had been unveiled by a whistle-blowing scientist sacked from the original inquiry, Ralph King. He said the original inquiry was wrong to blame a simple mechanical failure: "I realised that what we were really there for was to come up with a cause which would not embarrass the company". His criticism led to the HSE ordering laboratory experiments. The test results released in November 2000 seemed to back up Mr King's theory that the presence of water inside the reactors and the simultaneous shutting down of crucial equipment, generated a massive build-up of pressure that blew the valve apart.

What was the Flixborough disaster please?

Here's a few:

The Hillsborough Disaster was a human crush that occurred on 15 April 1989


Aberfan Disaster, 1966 A colliery slag heap collapsed buryng Pantglas Junior School in the Welsh village of Aberfan. The disaster claimed the lives of 116

Marchioness disaster occurred on the River Thames in London, England, in the early hours of 20 August 1989, when the pleasure boat Marchioness sank killing 30 people

Hi, I have to do a presentation re how human factors were the root cause of fatalities in disasters. I need at least four. I would rather not go for the obvious, Herald of Free Enterprize, Flixborough, Piper Alpha, Paddington rail disaster etc. Can anyone suggest others please? Regards
