CLAIRTON, Pa. (AP) — Explosions at a U.S. Steel plant that shook the ground near Pittsburgh left one dead and sent at least ten to hospitals Monday, with emergency workers still searching the badly charred rubble hours later for a missing worker, officials said.
One worker was pulled from the wreckage hours after the explosions sent black smoke spiraling into the midday sky in the Mon Valley, a region of the state synonymous with steel for more than a century. Allegheny County Emergency Services said a fire at the plant started around 10:51 a.m. A search and rescue effort was still active on Monday afternoon and officials said they had not isolated the cause of the blasts.
The explosions sent a shock through the community and led to officials asking residents to stay away from the scene so emergency workers could respond.
“It felt like thunder,” Zachary Buday, a construction worker near the scene, told WTAE-TV. “Shook the scaffold, shook my chest, and shook the building, and then when we saw the dark smoke coming up from the steel mill and put two and two together, and it’s like something bad happened.” Pennsylvania Gov. Josh Shapiro said via X that “multiple explosions” occurred at the facility.

An explosion Monday at a U.S. Steel plant near Pittsburgh has left dozens wounded and people trapped under the rubble, with emergency workers on site trying to rescue them, officials said. There are no confirmed fatalities at the Clairton Coke Works, said Abigail Gardner, director of communications for Allegheny County.
The Allegheny County Emergency Services said a fire at the plant started around 10:51 a.m. and that it has transported five people. The agency did not provide any more details on those people transported and would only say it was an "active scene."
The plant, a massive industrial facility along the Monongahela River south of Pittsburgh, is considered the largest coking operation in North America and is one of four major U.S. Steel plants in Pennsylvania that employ several thousand workers.
In June, U.S. Steel and Nippon Steel announced they had finalized a "historic partnership," a deal that gives the U.S. government a say in some matters and comes a year and a half after the Japanese company first proposed its nearly $15 billion buyout of the iconic American steelmaker.
