Kenexis President Ed Marszal has written and released a white paper on the concept of the Unified Hazard Assessment. This paper was presented at the 2019 Mary Kay O’Conner Process Safety Center conference in October of 2019. The full paper can be downloaded below.
Unified Hazard Assessment is an approach that will allow for HAZOP, LOPA, Hazard Registers, and Bowtie Analysis to all be performed from a single database using a single software tool. In order to gain the full power of unified hazard assessment, industry will need to do some standardization of how process hazard analysis data is structured, and formalize how PHA studies need to be documented, but the benefits are powerful. No longer will PHA data be an unusable and poorly organized document that is only useful for providing recommendations and “checking the box” for regulatory compliance. In the future, PHA data will be an evergreen tool for managing the implementation and usefullness of all process safety barriers.
