From the Abstract:
Process hazard analyses (PHAs) must be updated and revalidated every 5 years or sooner. PHA/HAZOP Revalidation is entirely different than a baseline or original PHA. The original textbook from CCPS on Revalidating PHAs was issued in 2001. This paper describes the current best practice approaches to revalidation and explains when to use each approach. The approaches are described in detailed flowcharts. Checklists for decisions making and quality control are provided, along with examples of completed documentation. This paper is based on completion of more than 300 Revalidations.
