Process safety management systems should be in place to ensure repeatability in operations.  A good system consists of higher level procedures that describe what to do.  At the plant level, the management system describes who does the activity and how it is done.  Following procedures leads to predictability in operations.  In 1996, Celanese had established a rigorous management system that consisted of 21 elements of process safety.  However, failure to rigorously apply several elements led to an explosion in our Cangrejera facility resulting in 2 fatalities.  This paper discusses the management system failures of conduct of operations, safe operating limits, standard operating procedures and training, and critical safety equipment management and how each failed due to a common weakness of management systems.
