Disastrous Dinners

Disastrous Dinners is a series of talks focusing on an accident or disaster and what can be learned from it. After the presentation, there will be a social dinner and drinks along with lots of time to continue the discussion.

The aim of Disastrous Dinners is to cover a wide range of accidents, including those from outside the process industries. As a result there should be something for everyone to learn from, whether they are a student, recent graduate or seasoned engineer.

Entry is Free of charge. Attendees will have to pay for their own food and drinks on the night.

I have frequently written some blog posts about disastrous dinners which are available as a separate feed

Event Poster

When most folk think of sugar, the idea that it could blow up and destroy a factory is not something they consider. But it did happen in 2008.

The thing is, the plant operators were aware of the hazard. They knew it was a hazard and that they had a problem for over 40 years, and yet it was never properly dealt with. This talk examines the reasons why and asks what can be done to avoid letting similar situations arrive in our own organisations.

Faulty Towers: A review of the Smiler Rollercoaster Accident

  • Presenter: David Sparkes
  • Date: Tuesday the 14th May 2019
  • Time: 18:30 for 19:00 start
  • Location: The Three Sisters, 139 Cowgate, Edinburgh EH1 1JS

Event Poster

Rollercoasters are intended to give us the illusion of danger, whilst actually being incredibly safe. However, in June 2015 the "Smiler" ride at Alton Towers went terribly wrong when two trains collided mid-track, seriously injuring four people.

The park's management initially blamed human error, but was this really the full story? This talk will summarise the findings of the HSE's own investigation to explain what happened and why. We will also discuss the parallels between this incident and others within the chemical industry. Could our own plants be just as prone to failure, and if so, what can we do to make sure they stay safe?

How a Nuclear Power Station Interfered With Food & Drink Supplies

  • Presenter: Iain Clenahan
  • Date: Wednesday the 27th of March 2019
  • Time: 18:30 for 19:00 start
  • Location: The Griffin, 266 Bath Street Glasgow, G2 4JP

Event Poster

The Hunterston B Nuclear Power Station uses carbon dioxide as reactor coolant, and a problem in 1997 resulted in a backflow of gas from a reactor’s circuit into the main storage tanks. This raised concerns, could contaminated carbon dioxide get transferred into a road tanker? Could this road tanker then contaminate other carbon dioxide users? What effect would this have on the food and drink industry? Join us for a talk by one of the chemical engineers involved in the investigation on behalf of the Secretary of State for Scotland to find out more including which essentials were affected.

The King's Cross Fire

Kings Cross Fire

  • Presenter: Alistair Marshall
  • Date: Wednesday the 13th of Febuary 2019
  • Time: 18:30 for 19:00 start
  • Location: The Southsider, 3-7 W Richmond St, Edinburgh EH8 9EF

Event Poster

On 18 November 1987 a fire on a wooden escalator broke out and ultimately resulted in 31 deaths. This talk will cover not just the details of the event but the culture within the London Underground and their attitudes to fires and safety more generally that contributed to the tragedy.
What can we learn from this event?
How can we avoid similar situations in the future?

The Boston Molasses Flood

Aftermath of the flood

  • Presenter: Sue Walker
  • Date: Tuesday the 15th of January 2019
  • Time: 18:30 for 19:00 start
  • Location: Behind The Wall, 14 Melville St, Falkirk FK1 1HZ behindthewall.co.uk

Event Poster

The Boston Molasses Flood occurred exactly 100 years ago and resulted in 21 deaths, mostly from suffocation or crushing. A 27m diameter molasses tank suddenly ruptured resulting in a 8m high wave of molasses racing out and trapping pedestrians and passers by. This talk will consider the design, construction and testing of the tank as well as the tank's Design Operating Envelope and will seek to identify lessons for today.
