DHA Revalidation
A DHA Revalidation is a systematic review and evaluation of a facility’s existing DHA with the intention of identifying all process, equipment and/or material changes that may have occurred in the facility in the five years subsequent to the most recent analysis. Proven techniques used for years to Revalidate Process Safety studies (HazOps, What-if Analyses, etc.) can be used to efficiently Revalidate DHAs.
