Trevor Asher Kletz, OBE, FREng, FRSC, FIChemE (1922–31 October 2013) was a prolific British author on the topic of chemical engineering safety. He is credited with introducing the concept of inherent safety, and was a major promoter of Hazop.
Early life and education
Kletz was born in 1922 in Darlington of Jewish parents, from a Russian immigrant background. He attended The King's School, Chester, then the University of Liverpool, where he graduated in chemistry in 1944 and joined ICI the same year. During the Second World War, he was a member of the Home Guard. In 1959 he married Denise (died 1980) and they had two sons.
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.
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.
Trevor Kletz, Hazard Analysis Pioneer, is the title of the article published on Kletz in the 2014 January issue of Chemical Engineering Progress, a publication of American Institute of Chemical Engineers (AIChE).
He was a Fellow of the Royal Academy of Engineering, the Royal Society of Chemistry, the Institution of Chemical Engineers, and the American Institute of Chemical Engineers. He was awarded medals by the latter two institutions.
