SALEM TOWNSHIP (KDKA) — It’s been more than 24 hours since a 30-inch gas line exploded in Salem Township.

A massive ball of fire shot into the sky, fueled by the ruptured gas line in a Westmoreland County pasture. Saturday, the flames were out but concern remained.

“We still have a potentially dangerous situation down there,” Chief Bob Rosatti with the Forbes Road Volunteer Fire Department said.

Security officers were posted near the blast site to prevent people from getting too close to a situation that emergency management officials still can’t approach.

“We’re still at the same point as we were yesterday we still have gas in the line,” Rosatti said. “It’s gonna take a while to draw the gas down.”

Spectra Energy officials were on scene Saturday, assessing damage, some of it up to half a mile from point of ignition.
