Walk the Line

摘要

DURING AN operation to return a filter back to service, a hydrocarbon spill resulted in a reportable quantity release and an API RP-754 Tier 1 process safety incident. The investigation found that the operator neglected to close the downstream bleed valve, causing the release. Corrective action included disciplining the operator. Does this scenario sound familiar? Ir likely will. Industry data indicate that greater than 20% of loss of primary containment (LOPC) incidents stem from a few causes: valves left open, open-ended lines on energized pipe and vessels, and line-up errors. More than 10% of these events occur during equipment startup [1].
