Definition of HAZOP

 

Hazard and Operability Analysis (HAZOP) is a structured and systematic technique for system examination and risk management.  In particular, HAZOP is often used as a technique for identifying potential hazards in a system and identifying operability problems likely to lead to nonconforming products.  HAZOP is based on a theory that assumes risk events are caused by deviations from design or operating intentions.  Identification of such deviations is facilitated by using sets of “guide words” as a systematic list of deviation perspectives.  This approach is a unique feature of the HAZOP methodology that helps stimulate the imagination of team members when exploring potential deviations.
