Feyzin Disaster

Review the Feyzin Disaster to see how this over pressure incident drove changes in the over protection standards.


While developing my training courses, I read many case studies; some of these case studies were game changing incidences, as they occurred on such a large scale that legislation was changed to reduce the likelihood of the event ever re-occurring. In particular, BLEVE explosions are so devastating that standards are constantly re-issued with the most current information.

The Feyzin Disaster which occurred in France in 1966. The result of this incident was that:

  • 18 people were killed;
  • a further 81 injured; and
  • extensive damage to property.

Below is a presentation highlighting how pressure relief acted during this incident and how changes have been made to standards to prevent similar circumstances from being repeated.

Please leave a comment as I value all feedback.
