An enormous fire engulfed a refinery in southwest Philadelphia early Friday, with explosions reported to have rocked nearby homes. Philadelphia Action News 6 reports the fire ripped through the Philadelphia Energy Solutions refinery at around 4 a.m. It’s the largest refinery on the East Coast, and CNBC reported gasoline futures prices jumped 3.4% at the news of the blast. City residents say the explosions knocked framed art and photos off the walls of their houses and that a thick plume of smoke covered the city center and the south. No evacuations have been ordered yet. Fire officials told the news channel that the fire is contained at the building structure, but is not yet under control; the Philadelphia Fire Department’s Twitter page says no injuries have been reported so far.
