An explosion at a U.S. Steel plant near Pittsburgh left one person dead and sent at least 10 to hospitals Monday and heavily damaged the sprawling facilty, with emergency workers still searching the badly charred rubble for a missing worker, officials said.
One worker was pulled from the wreckage hours after the explosion 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 the cause of the explosion was under investigation.
The explosion, followed by several smaller blasts, could be felt in the nearby community and prompted county officials to warn 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.”
At a news conference, Scott Buckiso, U.S. Steel’s chief manufacturing officer, did not give details about the damage or casualties, and said they were still trying to determine what happened. U.S. Steel employees “did a great job” of going in and rescuing workers, shutting down gases and making sure the site was stable.
