Modifications and HAZOP's

The Management of change element of PSM requires that a PHA be carried out when carrying out modifications. The problem I see in many companies is the lack of continuity of a PHA team due to resignations and retirements. However many checklists and procedure we write, a good PHA depends on the skills of the team leader. With people moving in and out as the PHA chair, the PHA study suffers. No PHA software can replace the skills of a trained PHA facilitator. Whenever a PHA facilitator is changed, go through your facilities management of organizational change procedures and ensure that the requirements of a PHA facilitator are met.
