(Clairton, PA) The family of thirty-nine-year-old Timothy Quinn of Fitz Henry in Westmoreland County, who was one of the two steelworkers who died in the explosion at U.S. Steel’s Clairton Coke Works plant outside of Pittsburgh on August 11th, 2025, has filed a lawsuit against the owner of U.S. Steel, Nippon Steel, accusing it and companies it has worked with of not taking steps that could have prevented the explosion that killed Quinn. The lawsuit that was filed last week, names as defendants Nippon Steel, which completed its purchase of U.S. Steel in the months before the explosion, along with MPW Industrial Services and Valves Incorporated. It claims they were all negligent. The lawsuit also accuses Nippon Steel of prioritizing revenue over worker safety. This stands in contrast to a common refrain from leaders of U.S. Steel that safety is a core value for the company.
