At least one person has died, and two people remain unaccounted for, while dozens have been injured following an explosion at the U.S. Steel Clairton plant on Monday.

First responders were alerted to the incident just before 11 a.m.  

Emergency workers were dispatched to rescue those trapped under rubble, according to The Associated Press.

Sources relayed to KDKA-TV that the explosion occurred inside the “reversing room” of the 13/15 battery. The room acts as a mechanical regulator, making sure the coal bakes evenly in the oven.

U.S. Steel responds to explosion

U.S. Steel issued the following statement Monday afternoon following the explosion.

“Around 11 a.m. ET on Monday, August 11, an incident occurred at U. S. Steel’s Clairton Plant, specifically at coke oven batteries 13 and 14. Emergency teams were immediately dispatched to the scene.

‘Our top priority is the safety and wellbeing of our employees and the environment. We are working closely with relevant authorities to investigate the cause of the incident and will provide additional updates as they become available. Nearly 1,300 dedicated men and women work at the Clairton Plant each day, performing their jobs with the utmost safety. During times like this, U. S. Steel employees come together to extend their love, prayers, and support to everyone affected.'” 

Clairton Mayor Richard Lattanzi spoke with KDKA-TV after the incident.

“The mill is such a big part of Clairton. For anyone that works, how old or young you are, you have to work every day, you need to go home healthy, and some people are not going to see the same husband or son or somebody that’s working the mill. It’s just a sad day for Clairton,” Mayor Lattanzi said.

Pennsylvania lawmakers react to explosion

Gov. Josh Shapiro and Lt. Gov. Austin Davis issued statements on social media, saying the administration is actively in touch with officials in Clairton. The Pennsylvania Emergency Management Agency and the Pennsylvania State Police have offered assistance.

“My team and I are tracking this explosion and waiting for more information. For those in the area, please listen to local officials and avoid the area,” Sen. Fetterman said. “Keeping those injured and all who are impacted in my thoughts right now.”

“Thinking about all those involved in and responding to the explosion at the steel plant in Clairton. I’m monitoring this closely as additional details become available, but in the meantime Dina and I will be praying for all those endangered and their families.”

“I’m closely monitoring the horrible tragedy at Clairton Coke Works,” Congressman Chris Deluzio (D) said. “My team and I are in touch with the United Steelworkers, United States Steel Corporation, and the Office of the Allegheny County Executive Sara Innamorato. I urge folks to follow guidance from local authorities and keep clear of the area. My heart goes out to these workers and their families, who will need all of us to rally around them.”
