Cause detail: INVESTIGATION OF THE INCIDENT FOUND HIGH PRESSURE GAS HAD ENTERED THE LUBE OIL SYSTEM DUE TO A FAILURE OF THE HIGH PRESSURE GAS SEAL. ONCE THE GAS ENTERED THE LUBE OIL SYSTEM, IT VENTED INTO THE BUILDING AND IGNITED. IT APPEARS THE EXPLOSION OCCURRED IN THE ROOF AREA OF THE BUILDING AND BLEW OUT SECTIONS OF WALL ON THREE SIDES. INSPECTION OF THE COMPRESSOR WHEEL REVEALED THE CAUSE OF THE INCIDENT. AT THE BOTTOM OF THE ROTOR, THERE WAS A PIECE OF METAL LODGED IN THE ROTOR. THE METAL WAS 6 TO 8 INCHES LONG AND APPROXIMATELY 1 INCH IN DIAMETER. IT APPEARS IT WAS LARGE ENOUGH TO HAVE JAMMED THE COMPRESSOR WHEEL CAUSING A CATASTROPHIC FAILURE OF THE GAS SEAL. COMPUTER PRINT OUT SHOWED ALL THE ALARMS FUNCTIONED AND INDICATED THE CHAIN OF EVENTS. BOTH ESD AND ESD II FUNCTIONED IMMEDIATELY, THUS ISOLATING THE COMPRESSOR UNIT FROM THE REST OF THE STATION. THE STATION CONTINUED TO RUN WITHOUT INTERRUPTION.
