Repairing Clairton, however, could be expensive, an investigation into the explosion could turn up more problems, and an official from the United Steelworkers union said it’s a constant struggle to get U.S. Steel to invest in its plants.

Two people are dead and 10 others injured after an explosion at U.S. Steel’s Clairton Coke Works near Pittsburgh. The recovery operation has ended, and the cause is under investigation.

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.

Authorities said their investigation has shifted to the cause of the explosion after they accounted for everyone who was missing.
