There have been many well publicized process industry accidents over the last several decades. Much has been written about them, and many lessons learned have been proposed. Yet evidence would indicate there has not been a lessening of industry accidents. More recent realization of the complexity of modern processes, and the organizations responsible for designing, building, running, and maintaining them, has resulted in a broader understanding of accident causation, and what can be done to try and prevent further incidents. This paper and presentation will review the previous thinking process and recommendations, and offer an alternative approach and recommendations.
