Hazard and Operability Study (HAZOP)

The design and operation of a process plant form an integral part of safety and systematic procedures, and techniques should be employed to identify hazards and operability and, where necessary, any hazards should be quantified. During the design of a new plant, the hazard identification procedure is repeated at intervals. This is first performed on the pilot-plant before the full-scale version is put in place. Potential hazards whose significance can be assessed with the help of experiments are often revealed by this study.
The hazard and operability study identifies a potential hazard. It provides little information on risk and consequences or its seriousness. However, by assessing the potential hazard, sometimes ...
