The team meetings should be managed by an independent, trained HAZOP Facilitator who is responsible for the overall quality of the review, partnered with a dedicated Scribe to minute the meetings. "The success of the HAZOP study strongly depends on the alertness and concentration of the team members and it is therefore important that the sessions are of limited duration and that there are appropriate intervals between sessions. How these requirements are achieved is ultimately the responsibility of the study leader."[1]
