The Clairton Coke Works are part of the four steel mills that make up the Mon Valley Works along the Monongahela River, near Pittsburgh. The mills were at the center of the Trump Administration-mediated merger between US Steel and Nippon Steel. Clairton, along with the other three Mon Valley mills, is expected to receive four billion dollars in much-needed upgrades from the merger agreement.

Senator John Fetterman arrived at the scene in Clairton shortly after news of the explosion broke.

UPDATE:

I’m still here at the Clairton Coke Works talking with workers, officials, and the community.

At least 1 confirmed dead, 10 injured, search and rescue still underway, air is safe but remain inside, and this is still an active scene.

Air quality is always a concern in the area of the mill, and as a precaution, the Allegheny County Department of Health had advised residents in the area to stay indoors, but lifted that advisory after tests showed no danger to the air quality.

THE LATEST: The Allegheny County Health Department is advising residents within one mile of the U.S. Steel Clairton plant to remain indoors, close all windows and doors, set HVAC systems to recirculate, and avoid activities that draw in outside air. https://t.co/y5hIrOlZOC

What may have caused the explosion is not known at this time, and an active search and rescue operation continues at the scene. At the time of this writing, the last remaining missing employee has not been found. Hope of finding him alive fades with each passing hour.

There will be questions that need to be answered and investigations that need to be held, but at this time, what Clairton needs the most is prayers.
