Two Dead in Pennsylvania Steel Plant Explosion

A major explosion at the Clairton Coke Works, a U.S. Steel plant near Pittsburgh, Pennsylvania, has resulted in two fatalities and injuries to ten others. The blast occurred on 11 August 2025 at approximately 10:51 a.m., followed by several smaller explosions that were felt in surrounding communities. The plant, the largest coking facility in North America, employs about 1,300 people and operates ten coke oven batteries, producing 4.3 million tonnes of coke annually.

Emergency crews conducted extensive search and rescue operations, locating all missing personnel by the evening. Five of the injured remain in critical but stable condition, while the others have been released from hospital care. Authorities issued a temporary shelter-in-place advisory for residents within a one-mile radius due to air quality concerns, which was lifted later in the day after monitoring showed pollutant levels within federal standards.

The cause of the explosion remains under investigation by local authorities and U.S. Steel. Two coke oven batteries affected by the blast have been shut down, while other operations at the facility continue. The plant has a documented history of environmental compliance issues, including fines and mandated upgrades to pollution control equipment in recent years.
