Lack of visibility into the operations and maintenance of functional safety equipment introduces significant uncertainty about the safety of the plant. Tier 3 indicators can be considered as either leading or lagging depending on how the data is processed. Leading indicators of Tier 3 are key to preventing Tier 2 or even Tier 1 events.
