The Hazard and Operability Analysis (HAZOP) technique was developed to identify and evaluate safety hazards in a process plant and to identify Operability problems which, although not hazardous, could compromise the plant's ability to achieve design productivity. Although originally developed to anticipate hazards and Operability problems for technology with which organizations have little experience, it has been found to be very effective for use with existing operations
