Layer of protection analysis (LOPA) is the newest methodology for hazard evaluation and risk assessment. On a sliding scale of sophistication and rigor, LOPA lies between the qualitative end of the scale (characterized by methods such as hazard and operability [HAZOP] analysis and what-if analysis) and the quantitative end (characterized by methods using fault trees and event trees). LOPA helps the analyst make consistent decisions on the adequacy of existing or proposed layers of protection against an accident scenario. The technique is ideally suited for companies striving to meet specific risk targets or to lower risk as low as reasonably practicable (ALARP).
Background and prior training in qualitative hazard evaluation methodologies (such as previous attendance at Process Hazard Analysis Leader training or the equivalent) are strongly recommended because LOPA builds on the skills and knowledge needed for hazard evaluations.
