Part B - Identification of Hazards - IChemE

What is a 'HAZOP' Study? See . HAZOP Guide to Best Practice Second Edition (IChemE 2008) A HAZOP study is a, systematic, structured technique for identifying potential failures of rigorous equipment or plant systems which may otherwise become HAZARDS or OPERABILITY PROBLEMS. Ideally, the process is carried out during the design phase of a ...

HAZOP Hazard and Operability Study

The HAZOP study should preferably be carried out as early in the design phase as possible - to have influence on the design. On the other hand; to carry out a HAZOP we need a rather complete design. As a compromise, the HAZOP is usually carried out as a final check when the detailed design has been completed.
