FILE - In this June 21, 2019 file photo, flames and smoke emerge from the Philadelphia Energy Solutions Refining Complex in Philadelphia. Federal investigators say an aging, failed elbow pipe appears to be the cause of the June fire and subsequent explosions that left five people with minor injuries and destroyed part of the processing unit at the largest oil refinery on the East Coast. The U.S. Chemical Safety and Hazard Investigation Board released a preliminary report Wednesday, Oct. 16 on findings from the June 21 explosion at the Philadelphia Energy Solutions Refining Complex.
