Incident Narrative

"ON MAY 25, 2025, AT 7:57 A.M., WHILE MAINTENANCE WAS BEING PERFORMED BY AN ENERGY TRANSFER COMPANY (ETC) EMPLOYEE AND A CONTRACT EMPLOYEE, THE WEST SLASH UNIT 2 COMPRESSOR, CAUGHT FIRE. THE ETC EMPLOYEE NOTIFIED THE OPERATIONS MANAGER WHO THEN NOTIFIED EMERGENCY SERVICES. THE EMPLOYEE AND CONTRACT EMPLOYEE ACTIVATED THE EMERGENCY SHUT DOWN SYSTEM (ESD) SUCCESSFULLY SHUTTING DOWN THE COMPRESSOR STATION. BOTH THE ETC EMPLOYEE AND CONTRACT EMPLOYEE WERE INJURED WHEN THE FIRE IGNITED. WHEN EMERGENCY SERVICES ARRIVED AT THE LOCATION THE TWO INJURED RECEIVED MEDICAL ATTENTION AND THE FIRE WAS EXTINGUISHED. THE INTERNAL INVESTIGATION FOUND THAT EMPLOYEES FAILED TO PROPERLY FOLLOW THE LOCKOUT/TAGOUT PROCEDURE LOCATED IN S-230 HAZARDOUS ENERGY CONTROL SECTION XII. THE INVESTIGATION ALSO FOUND THAT THE EMPLOYEES WRONGFULLY OPENED A VALVE ALLOWING THE NATURAL GAS LINE PRESSURE TO PURGE DEBRIS FROM THE CYLINDERS. THE RELEASED GAS THEN FOUND AN IGNITION SOURCE SUPPLIED BY ONE OR MORE OF THE RUNNING NATURAL GAS COMPRESSORS RESULTING IN THE FIRE. THE PLAN TO PREVENT RECURRENCE IS AS FOLLOWS: 1) SAFETY STAND DOWN FOR THE ENTIRE WESTER DIVISION TO REVIEW LOCKOUT/TAGOUT PROCEDURES AND ACCEPTABLE CLEANING MEDIA. 2) RETRAIN SITE EMPLOYEES ON S-230 WITH AN EMPHASIS ON THE PROPER LOCKOUT/TAGOUT PROCESS."
