Deadly Explosion Occurs At U.S. Steel Plant, Workers Trapped Underneath Rubble

Prayers are needed for steelworkers in Pittsburgh.

A massive explosion occurred on Monday afternoon at the U.S. Steel Clairton plant in Pennsylvania.

Authorities have reported that dozens have been injured, and one person has been reported dead.

Several workers are reportedly trapped underneath the rubble.

CBS had more to report on the deadly explosion:

At least one person has been killed 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.

Others were trapped under rubble, with emergency workers on site trying to rescue them, 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.

UPMC officials confirmed to KDKA-TV that they have received two patients at UPMC Mercy Hospital. An Allegheny Health Network spokesperson also confirms that “multiple AHN hospitals are receiving inbound patients.”

Here are some scenes from the explosion:

ABC News reported more on the workers who are trapped underneath the rubble:

A rescue operation is underway for people trapped under rubble following an explosion at a Pennsylvania steel plant, county officials said.

It’s not clear how many people are trapped from the blast at the US Steel Clairton Coke Works plant in Clairton, about 15 miles outside of Pittsburgh.

Allegheny County Director of Communications Abigail Gardner said the Health Department is on site monitoring air quality and Gov. Josh Shapiro said his administration is in touch with officials.

“The scene is still active, and folks nearby should follow the direction of local authorities,” the governor said on social media. “Please join Lori and me in praying for the Clairton community.”
