Hi Barbara,

   Thank you for the link. it makes sobering reading and perhaps should be a mandatory part of any MBA course to focus management.

   If I get any criticism about the cost of engineering I am just going to send the person this link.

   Cheers

   Geoff Stone

   Information regarding the probable cause of the explosion at the Flixborough plant can be found on the UK's HSE website:

http://www.hse.gov.uk/comah/sragtech/caseflixboroug74.htm

A leak had been found in a reactor, and a temporary 20" bypass had been installed, which appears to have been the source of the explosion, though a fire on a separate 8" line may have been partially responsible.

Excerpt from HSE Accident Summary:
"During the late afternoon on 1 June 1974 a 20 inch bypass system ruptured, which may have been caused by a fire on a nearby 8 inch pipe. This resulted in the escape of a large quantity of cyclohexane. The cyclohexane formed a flammable mixture and subsequently found a source of ignition. At about 16:53 hours there was a massive vapour cloud explosion which caused extensive damage and started numerous fires on the site."

It will be interesting to see if sufficient evidence is found at Buncefield to determine the cause of the recent explosion in the oil tanks. There isn't anything on the HSE website yet which is not surprising.

Barbara
