Hazard and Operability Study Method (HAZOP)

Aims & Benefits

This 4-day course aims to provide an understanding of ‘hazard and operability study method (HAZOP). HAZOP is highly practical and widely proven method of hazard analysis. It is applied to determine the likelihood of unscheduled events arising in normal operations which require appropriate mitigating action to be taken.

In this training programme the candidate will get the opportunity to learn and understand the need and relevance of HAZOP. Recognise those operability problems revealed by HAZOP study which cannot be answered satisfactorily on a qualitative basis and hence merit further evaluation by quantitative means to establish occurrence probability and frequency levels.
