Reuters report that a new refinery in the USA which was being commissioned had an inadvertent slippage of caustic into the system. Apparently the caustic caused severe corrosion of the major equipment in the refinery when the temperature of the unit was increased as part of the start up process. operators came to know of the problem when they started having leaks and fires. The damage apparently is huge and about 50 heat exchangers have to be cleaned. The process hazard analysis of the plant should have spotted the possibility of caustic leaking into the system. While I do not know the reason for the incident, today what I see in HAZOP studies is the competency of the team is coming down and the net result is a poor study output. The onus is more and more on the chair to guide the team properly, No PHA software can do this for you.
