Incident Narrative
"ON 7/31/21, A CREW WAS PERFORMING REMEDIATION ON AN EXTERNAL CORROSION FEATURE IDENTIFIED FROM A RECENT ILI. AFTER THE ANOMALY WAS INSPECTED, THE SITE WAS CHECKED FOR AND CONFIRMED TO HAVE NO LELS. AT 13:25, WHILE WELDING ON A B SLEEVE ON THE SD-1 PIPELINE AND AFTER MAKING THE 2ND PASS (HORIZONTAL) ON THE WEST SIDE OF THE PIPELINE, THE WELDER OBSERVED A SMALL 1"" FLAME AT THE END OF THE SLEEVE AND NOTIFIED THE INSPECTOR. ALL PERSONNEL EVACUATED FROM THE DIG SITE. A LEAK WAS VERIFIED USING AN LEL MONITOR. LIQUID CONTROL WAS NOTIFIED AND SHUTDOWN THE LINE. THE PIPELINE WAS PURGED AND THE B-SLEEVE INSTALLATION WAS COMPLETED TO REMEDIATE THE EXTERNAL CORROSION FEATURE."
