CSB: "U.S. Chemical Safety Board Opens Investigation into Fatal Incident at U.S. Steel Clairton Coke Works Plant in Pennsylvania"

Via the Chemical Safety Board:  

Washington D.C. August 12, 2025 – The U.S. Chemical Safety and Hazard Investigation Board (CSB) is sending a team to investigate the fatal explosions and fires at U.S. Steel’s Clairton Coke Works plant in Clairton, Pennsylvania, that occurred on August 11. Two people were fatally injured, and at least ten others were injured and sent to area hospitals for medical treatment.

CSB Chairperson Steve Owens said, “The CSB will work to determine the cause of this tragic incident and identify actions that can be taken to help ensure that a similar disaster like this does not happen again.”

The Clairton Coke Works facility processes raw coal into coke, which is then used as a primary component in steelmaking. The massive, 392-acre facility is located about 15 miles outside of Pittsburgh and is considered the largest coking facility in North America. Nearly 1,300 employees report to the facility daily.

I admire the CSB in continuing in its mission as it is threatened with budget cuts. Full release here.
