Introduction This BakerRisk Best Practice document provides general guidance for performing highly effective HAZOP studies. Note that the guidance is not rigid; it is our opinion that there is no one 'best' way to perform a HAZOP, and the optimal methods will depend on what is being studied, the makeup of the study team, and many other factors.
