An explosion at the U.S. Steel Clairton Coke Works about 15 miles southeast of Pittsburgh has left one dead and at least 10 injured, with some people still trapped under the rubble as emergency worker

The explosion, followed by several smaller blasts, could be felt in the nearby community and prompted county officials to warn residents to stay away from the scene so emergency workers could respond.

Don Furko is a mechanical maintenance planner who this week reached his 25th anniversary at the plant. He was working in a different area with the blast took place.
