TARGET CUSTOMERS
LOPA can be used at any point in the life cycle of any given project or process, but it is most cost effective when implemented during front-end loading when process flow diagrams are complete and the P&IDs are under development.
For existing processes, LOPA should be used during or after the HAZOP review or
revalidation. LOPA is typically applied after a qualitative hazards analysis has been completed, which provides the LOPA team with a list of hazard scenarios with associated-consequence descriptions and potential safeguards for consideration.
