As WLT Report previously reported, a massive explosion occurred Monday afternoon at Pennsylvania’s U.S. Steel Clairton plant.
A new update from authorities has revealed that two people have died in the explosion and 10 people have been injured.
A preliminary report revealed that the explosion occurred between two batteries at the plant.
NBC News reported more details on the explosion:
Two people were killed in an explosion Monday morning at a steel factory in the Pittsburgh area.
Officials said Monday night that a person who had been missing was confirmed dead.
“It is with profound sadness that I share with you that the U. S. Steel colleague who had been unaccounted for has been located and confirmed deceased, following an extensive search and rescue effort,” David Burritt, the company’s CEO, said in a statement.
At least 10 people were injured in the blast, officials said.
Five were in critical but stable condition Monday night, Allegheny County officials said in an update. Five people were taken to the hospital and were treated and released.
Officials said others had been injured and treated at the scene, but they did not provide a number.
Investigators are working to determine the origin and cause of the explosion, officials said.
“Obviously this is a tragedy we want to understand,” said Scott Buckiso, Executive Vice President and Chief Manufacturing Officer for U.S. Steel
The blast ignited shortly before 11 a.m. between two batteries at Clairton Coke Works, officials said.
The U.S. Steel facility southeast of Pittsburgh annually produces millions of tons of commercial coke, a type of fuel used in a steel production.

Fox Business covered how Pennsylvania politicians responded:
Pennsylvania Sen. John Fetterman said there was an active search and rescue underway with dozens injured.
Clairton Mayor Rich Lattanzi also told KDKA-TV that there have been reports of multiple injuries.
Lattanzi said he heard that the explosion happened in the “reversing room between thirteenth and fifteenth battery,” which is part of the control system of the coking factory.
“They have a tough job, and it’s a dangerous job,” Lattanzi said of the plant workers. “My heart bleeds for every one of them and their families.”
