(NewsNation) — Officials said multiple explosions at a U.S. Steel plant in Clairton, Pennsylvania, left one person dead and many more injured, with emergency workers actively searching the rubble for more people.

Allegheny County Emergency Services said a fire at the plant started around 10:51 a.m. Monday at the U.S. Steel Clairton Coke Works, and it confirmed the death and injuries, many of which are not life-threatening.

The agency later made a statement calling the explosion “a Level 3 mass casualty incident” to allow for more EMS resources from across the region to respond. Police say there is one person still unaccounted for.

Pennsylvania Gov. Josh Shapiro said all injured employees have been sent to a local hospital to receive care.

“Lori and I are eternally thankful for the bravery of our first responders — and we continue to pray for the entire Clairton community,” Shapiro said in a post on social platform X.

“It was a terrible incident and my prayers go out to all the families affected by this,” Clairton Mayor Richard Lattanzi said in a Facebook post. “There are people hurt and that is the utmost importance.”

The Allegheny Health Department is advising residents within one mile of the plant to remain indoors, close all windows and doors, set HVAC systems to recirculate and avoid activities that draw in outside air, such as using exhaust fans, “out of an abundance of caution.”

“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,” U.S. Steel President and CEO David B. Burritt said in a statement to NewsNation.

The Bureau of Alcohol, Tobacco, Firearms and Explosives announced that its Pittsburgh field office is assisting in efforts related to the explosion.

U.S. Steel said it would be working closely with authorities in the investigation into what caused the explosion.
