7.2.1.2 Indicator Data CaptureA Tie

7.2.1.2 Indicator Data CaptureA Tier 3 PSE is counted for each SOL excursion that occurred in a specified time period.A company may want to record the duration of individual SOL excursions and may even calculate the total duration ofall SOL excursions.A single initiating event may result in multiple SOL excursions (e.g. facility-wide failure of a utiliy) and each excursionshould be counted as a separate Tier 3 PSE. A process condition that hovers near the SOL value may result inmultiple excursions. These excursions should be counted as a single Tier 3 PSE.7.2.2 Primary Containment Inspection or Testing Results Outside Acceptable Limits7.2.2.1 Indicator DefinitionAn inspection or test finding that indicates primary containment equipment has been operated outside acceptablelimits. These findings typically trigger an action, such as replacement-in-kind, repairs to restore ftness-for-service,replacement with other materials, increased inspection or testing, or de-rating of process equipment.7.2.2.2 Indicator Data CaptureA Tier 3 PSE is counted for vessels, atmospheric tanks, piping, or machinery when previous operating pressures orlevels exceed the acceptable limits based upon wall thickness inspection measurements.A single Tier 3 PSE is recorded for each pressure vessel or atmospheric tank regardless of the number of individualtest measurements found to be below the required wall thickness.
