This series of essays on safety and loss prevention is aimed at helping the process industries avoid accidents and improve its public image. The central message is the apparent inability of organizations to learn, and retain in the long term, the lessons drawn from accidents. Thus incidents of a similar type recur within the same company at intervals of a decade or so, as personnel involved move on to other jobs. Kletz illustrates his thesis copiously with cases which provide advice for engineers. He also offers his own advice on how to improve the corporate memory.
