A major explosion shook a steel plant in Clairton, Pennsylvania, on Monday, injuring multiple people and sending thick plumes of smoke into the sky over the Pittsburgh metropolitan area. The blast sparked a fire that emergency crews have been battling for hours, with heavy flames still visible from a distance.
Witnesses reported hearing a loud boom in the early part of the day, followed by sirens and a rush of emergency vehicles toward the facility. Video and photos from the scene show dark smoke rolling over nearby neighbourhoods as firefighters worked to contain the blaze and prevent it from spreading further inside the plant.
The incident prompted an immediate response from state and local officials. Pennsylvania Governor Josh Shapiro addressed the situation on the social media platform X, saying his administration was in direct contact with local authorities in Clairton. He urged residents in the area to follow safety instructions, such as staying indoors or avoiding the vicinity of the plant. “The scene is still active, and folks nearby should follow the direction of local authorities,” Shapiro wrote, also calling on Pennsylvanians to keep the injured and the community in their prayers.
As of Monday evening, authorities had not confirmed the cause of the explosion. Details about the exact number of people hurt and the severity of their injuries were still unclear. Local officials said emergency crews remained on high alert at the site, working not only to control the flames but also to secure the area in case of any further incidents.
Clairton, located about 15 miles south of Pittsburgh, has long been known for its steel production, and the plant plays a significant role in the local economy. The sudden blast has left many residents shaken, with concerns about both the safety of workers and the potential environmental effects from the smoke and debris. Investigators are expected to begin examining the site once it is safe to enter, but for now, the focus remains on putting out the fire and protecting the surrounding community.
