CLAIRTON, Pa. — An explosion at the U.S. Steel Clairton Coke Works plant on Monday resulted in two fatalities and ten injuries, according to Allegheny County police. The incident occurred around 10:51 a.m. and trapped several individuals under debris, prompting a swift rescue operation.

Among the injured, five individuals are reported to be in critical but stable condition, while five others were treated and released from local hospitals. Pennsylvania Governor Josh Shapiro expressed gratitude for the first responders' efforts, stating, "Injured employees have now been transported to local hospitals to receive care, and search-and-rescue efforts remain active at the plant. Lori and I are eternally thankful for the bravery of our first responders — and we continue to pray for the entire Clairton community."

One of the deceased has been identified as Timothy Quinn, as confirmed by Clairton Mayor Richard Lattanzi. The identity of the second victim, who was discovered later that evening, has not yet been released.

The explosion originated in a battery operating area of the plant, with reports of multiple secondary explosions following the initial blast. David B. Burritt, president and CEO of U.S. Steel, stated, "We are working closely with relevant authorities to investigate the cause of the incident. 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."

In light of the explosion, Allegheny County Executive Sara Innamorato advised residents living within one mile of the plant to stay indoors, close all windows and doors, and set HVAC systems to recirculate air. She also urged residents to avoid activities that could draw in outside air, such as using exhaust fans.

The Allegheny County Health Department is actively monitoring the situation. Innamorato reported that air quality monitors have not detected any increases in PM 2.5 or sulfur dioxide levels above federal standards.
