Facility a petroleum refinery where regulated Substances and other extremely hazardous substances are produced, processed, stored, and handled, and from which an accidental release could occur. On July 23, 2014, a fire occurred at the control valve station on Pass #3 to Vacuum Tower Heater H-1-1601 while facility operators were isolating flow control valve 02FC23 for replacement. While isolating the flow control valve, operators prepared the line on Pass #3 bleeder valve using a rod-out tool. The rod-out tool used by operators was too short to clear the bleeder valve allowing hot hydrocarbons substances to remain in the piping that were subsequently released.
