Join Kenexis President Ed Marszal at the Mary Kay O’Conner Process Safety Center conference on October 23 for a discussion of Unified Hazard Assessment. UHA is the next evolution on process hazards analysis that will unify HAZOP, LOPA, Hazard Registers, and Bowtie all in one unified data structure and editing tool (Open PHA). This new approach will maximize the value of the investment in PHA by allowing the information to be leveraged for a variety of purposes instead of being locked in silos the prevent productivity. One exiting outcome of this approach, as shown in the graphic, is performing quantitative LOPA calculation in a bowtie diagram to aid in understanding, while carrying forward all calculations.
