I met Professor Trevor Kletz in 2001, at the Hazards Symposium in Manchester.
I was captivated from the first words of his presentation. Here was a wise person with an enormous experience in the safety domain, with a lot of knowledge and very clear explanations. 
Professor Kletz is the best motivational speaker I ve ever met- there was a real pleasure to listen to his presentations at the different Hazards Symposiums. 
One of the most important ideas got from the presentations of professor Kletz is the necessity to capture, store and re-use heuristic safety knowledge- in order to prevent the repeating of unexpected events.
Other idea- implemented as much possible in this blog- is represented by the need to communicate and disseminate your experience. The newsletter system implemented by professor Kletz in his activity at ICI is today examples of best practice in safety.

After graduating in chemistry at Liverpool University in 1944, Trevor Kletz joined Imperial Chemical Industries (ICI) and spent eight years in research, sixteen in production management and the last fourteen as safety adviser to the Petrochemicals Division. In ICI he worked initially as a research chemist, then became plant manager (in turn) of iso-octane, acetone and tar acids plants. After further experience in process investigation and commissioning in the Technical Department, in 1961 he became assistant works manager on the Olefines works. In 1968, he was appointed the first Technical Safety Advisor. 
During this time, ICI developed hazard and operability studies, now known as Hazop, for which he was an enthusiastic advocate, and the author of the first book on the subject.
When he retired in 1982 he had established a safety culture within the company based on communication, and had begun a second career and an international reputation as an author and speaker. Most of his books are concerned with case studies from industry and the human and technical causes. Shortly after his retirement he expanded a paper entitled "What you don't have, can't leak” into the book which began the concept of inherent safety

 In 1978 he was appointed an Industrial Professor at Loughborough University. On retiring from ICI in 1982 he joined the University full-time; in 1986 he became a Visiting Fellow and is now a Visiting Professor at Loughborough and has been one at Texas A&M University.
He has written eleven books and well over a hundred reviewed papers on loss prevention and process safety. He was appointed an OBE in 1997.
