Greater numbers of action items are being generated from the LOPA process as itbecomes increasingly utilized as a method for risk evaluation. The quantity and type ofaction items result from the combination of initiating events, conditional modifiers, andprescribed guidelines. The quality of the inputs determines whether the action items willactually provide any additional safety benefit. This paper is not a procedure forperforming a LOPA analysis, but presents issues to be aware of when generating a list ofinitiating events, evaluation of the initiating event severities, and the influence ofconditional modifiers.
