This is Trevor Kletz's follow up to his extremely successful What Went Wrong? Case Histories of Process Plant Disasters. In it, Kletz reinforces the messages in his now-classic book of famous case histories, but the majority of the book covers points not covered in the original. This new volume will focus more on procedural changes that can be made, not only at the technical or engineering levels, but at the managerial level, to prevent disasters from happening.
