Pennsylvania

PHILADELPHIA (AP) – Authorities say a fire in a Philadelphia refinery struck by explosions and a pre-dawn blaze last week has now been extinguished as an investigation is launched into what caused it.

Fire department and city officials said in a statement Sunday the blaze at the Philadelphia Energy Solutions Refining Complex was extinguished Saturday afternoon. Officials said the gas valve that had been fueling the blaze has been shut off and the tank involved in the explosion has been isolated.

Officials say the fire department’s hazmat unit and the public health department are still monitoring air quality. No threat to public health has been reported.

Five workers were treated for minor injuries after the 4 a.m. Friday fire at a tank containing a mixture of butane and propane.
