A CEGT TECHNICIAN FAILED TO RETURN ALL VALVES TO THEIR FOUND POSITION UPON COMPLETION OF THE WORK TASK RESULTING IN ACTIVATION OF THE COMPRESSOR ESD SYSTEM. UPON ACTIVATION OF THE COMPRESSOR ESD SYSTEM BOTH THE SUCTION AND DISCHARGE ESD VALVES FAILED TO CLOSE. AN INCIDENT INVESTIGATION FOUND THAT DEBRIS PRESENT IN THE VALVES CAUSED THEM TO BIND OR SEIZE EFFECTIVELY DISABLING OPERATION OF THE VALVES.\n\nPHMSA trend classification: not significant, not serious.\n\nPHMSA standardized cause: INCORRECT OPERATION — INCORRECT VALVE POSITION.\n\nPHMSA indexed costs: $16,575 reported total cost, $13,564.146 in 1984 dollars, $17,240.064 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data.
