Cause detail: ON 12/30/2014, MAINTENANCE PERSONNEL WERE PREPARING TO REPLACE A VALVE USING A STOPPLE AND A BLOCK VALVE. WHILE THE WORK WAS BEING PERFORMED, THE STOPPLE SEALING ELEMENT HAD DEVELOPED A SMALL LEAK. DURING THE PROCESS OF RETRACTING THE STOPPLE SEALING ELEMENT FOR REPLACEMENT, THE INSULATION FLANGE GASKET ON THE VALVE BEING REPLACED FAILED BEFORE THE SECOND SEALING ELEMENT WAS INSERTED. THE AFFECTED PIPE SEGMENT WAS ISOLATED AND BLOWN DOWN. THE VALVE INITIALLY BEING REPLACED WAS REMOVED AND REPLACED WITH A NEW VALVE AND NEW INSULATION GASKET. THE INSULATION GASKET WAS NEAR ITS LIFE EXPECTANCY. GASKET AGE COMBINED WITH THE MAINTENANCE WORK RESULTED IN ITS FAILURE.
