Narrative
In preparation for the tank cleaning on tank 1078, contract personnel were in final preparation for entering the internal floating roof tank. They were located at the top entry into the tank. Local operations had performed the lo/to on the manifold and tank valves to fully isolate the tank from the facility. At approximately 10:25, personnel on the roof heard a loud pop and looked over the railing noticing that the expansion fitting on the 8" inlet piping had failed due to thermal pressure buildup. Updated per blaine keener e-mail due to changes in PHMSA reporting form.
