Guidelines for Revalidating a Process Hazard Analysis
Wiley-AIChE (Verlag)
978-1-119-64360-9 (ISBN)
This book is derived from the experience of many companies in the chemical and hydrocarbon processing industries, and presents demonstrated, concise, and common sense approaches for a resource-effective revalidation of process hazard analyses (PHAs). It includes flowcharts, checklists, and worksheets that provide invaluable assistance to the revalidation process.
The new edition, now as a guideline, provides a compete and thorough update of the first book and will provide much needed and requested guidance on PHA Revalidations including evaluating Prior PHA Studies, Identifying an Appropriate Revalidation Methodology, Preparing and Conducting the Revalidation Study Sessions, and Documenting the Revalidation Study.
The Center for Chemical Process Safety (CCPS) has been the global leader in developing and disseminating information on process safety management and technology since 1985. It has published over 100 books in its process safety guidelines and process safety concepts series and created over 30 training modules through its Safety in Chemical Engineering Education series.
