On this week’s Journalist Roundtable, reporters examined the August 11 explosion at U.S. Steel’s Clairton Coke Works that killed two workers and injured ten others.

U.S. Steel says its initial investigation points to a gas valve failure. According to the company, pressure built up inside the valve while workers were flushing it during maintenance preparations. The release of coke oven gas is believed to have found an ignition source, triggering the deadly blast.

Reid Frazier of The Allegheny Front noted that the Clairton plant has a long history of safety and maintenance problems. “There was a fatal explosion here in 2009, another blast that injured 20 workers in 2010, and a fire in 2018 that disabled pollution controls for months,” he said.

Jordan Wilkie of WITF shared the perspective of a Clairton resident who heard the August 11 blast. The resident described not only the fear of the explosion itself but also ongoing struggles with air quality and pollution tied to the coke works.
