Driver injured at rolled metal plant blast in Farrell, Pa.

FARRELL, Pa. (AP) — The driver of a tanker truck was burned and another worker was treated for cuts after an explosion at a rolled metal plant in western Pennsylvania.

An official with Duferco Farrell Corp. has confirmed the injuries for The Associated Press, but says another official will release more information later in the day.

Mercer County dispatchers say the explosion was reported when a driver was dropping off a load of hydrogen at the factory in Farrell. It was not immediately clear if the tanker exploded or something in the factory exploded, or both.

Plant officials worked overnight after the explosion was reported about 6:30 p.m. Sunday. Several workers at the plant were evacuated but not hurt.

The driver was hospitalized, but his condition was not immediately available.
