What is HAZOP? - Industrial Plant Safety

A hazop takes 1.5-3 hours per main plant item (still, furnace, reactor, heater, etc.). If the plant is similar to an existing one it will take 1.5 hours per item but if the process is new it may take 3 hours per item. Meetings are usually restricted to 3 hours, twice per day, 2 or 3 or even 4 days per
