A gas explosion has leveled a building on the grounds of a central Pennsylvania steel plant.
Steelton Mayor Thomas Acri tells Pennlive.com that no one was hurt in the blast and subsequent fire at the ArcelorMittal plant Sunday afternoon.
No one was inside the building when it exploded around 1 p.m. The cause of the gas leak remains under investigation.
The fire brought more than 90 first responders to the grounds. Officials from UGI Utilities were there to investigate and help firefighters.
The steel plant dates to 1867 and was formerly part of the Bethlehem Steel Corp. ArcelorMittal says the plant was the first built specifically for the production of steel in the United States.
