Incident Narrative
"A PROJECT WAS UNDERWAY AT THE JOHNSONS CORNER STATION THAT INVOLVED ISOLATION AND DRAIN DOWN OF THE 7100 MANIFOLD AND 36-INCH TANK LINE. THE MANIFOLD AND TANK LINE HAD BEEN TAKEN OUT OF SERVICE, DRAINED OF PRODUCT, AND MECHANICALLY AND ELECTRICALLY LOCKED OUT / TAGGED OUT PRIOR TO CONTRACTORS COMMENCING THE WORK ACTIVITY WHICH WAS UNDERWAY AT THE TIME OF THE ACCIDENT. A MECHANICAL ISOLATION TOOL HAD BEEN INSTALLED IN THE 36-INCH TANK LINE AND A PRODUCT VAPOR IGNITION OCCURRED AS PIPE BEVELING ACTIVITY WAS BEING PERFORMED IN PREPARATION FOR WELDING AND TIE-IN WORK. AN INVESTIGATION INTO THE ACCIDENT DETERMINED THAT THE MECHANICAL ISOLATION TOOL UTILIZED WAS NOT APPROPRIATE FOR THE WORK BEING PERFORMED AND ALLOWED PRODUCT VAPOR TO PASS BY THE TOOL SEAL. IT WAS LATER IDENTIFIED THAT THE FOREMAN'S PLUG ALONE WAS NOT SUITABLE FOR THE ISOLATION OF VAPORS. AS THE PIPE BEVELING ACTIVITY WAS OCCURRING THE VAPOR IGNITED."
