Clairton Coke Works explosion: 1 killed, 1 unaccounted for and at least 10 injured after explosion at U.S. Steel plant in Pennsylvania
One person has died, one person is unaccounted for and at least 10 are injured following an explosion at a U.S. Steel plant near Pittsburgh, Allegheny County Police Assistant Superintendent Victor Joseph said at a press conference Monday afternoon.
The explosion erupted at Clairton Coke Works around 10:51 a.m. ET on Monday. While the plant is stable, an active investigation is underway, Scott Buckiso, the executive vice president and chief manufacturing officer at U.S. Steel, said.
Clairton Coke Works sits along the Monongahela River, about 20 miles south of Pittsburgh, and is part of the U.S. Steel manufacturing group based out of western Pennsylvania. Plants like this heat up coal to produce coke, a carbon-rich substance that's crucial for creating steel. Clairton Coke Works is considered the largest coke plant in North America, according to U.S. Steel, and produces around 4.3 million tons of coke annually. Nearly 1,300 people work at Clairton Plant, David B. Burritt, the president and CEO of U.S. Steel, said in a statement on X.
'We are working closely with relevant authorities to investigate the cause of the incident and will provide additional updates as they become available," Burritt said.
The explosion reportedly took place inside the plant's 'reversing room,' sources told Pittsburgh KDKA reporter Ricky Sayer, which is a specialized area within the coke producing oven that's designed to help control air and gas flows during the coal heating process.
'Felt like thunder,' Zachary Buday, a construction worker who was near the scene at the time of the explosion, told local ABC affiliate 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.'
Pennsylvania Gov. Josh Shapiro said in an X post that his administration was in touch with local officials.
'The scene is still active, and folks nearby should follow the direction of local authorities,' Shapiro wrote. 'Please join Lori and me in praying for the Clairton community.'
Over the last few years, Clairton Coke Works has faced a number of lawsuits over pollution concerns. Most recently, in 2019, the plant settled a 2017 lawsuit for $8.5 million and agreed to spend at least $6.5 million to reduce its soot emissions and noxious odors.
'The mill is such a big part of Clairton,' Clairton Mayor Richard Lattanzi said Monday afternoon, according to the AP. 'It's just a sad day for Clairton.'

Study gives recommendations on how ABQ Ride can improve safety on buses
ALBUQUERQUE, N.M. (KRQE) – The City of Albuquerque is fine-tuning its recent overhaul of security on city buses, after a study revealed some gaps. The recommendations in the study completed last year focus on getting more security staff in the field, and getting them to incidents faster. 'This plan is not something that's meant to last for a season or two, it's here to stay,' said Bobby Sisneros, Deputy Director for ABQ Ride.

Governor New Mexico Crime Files: Mother high on fentanyl nearly kills crossing guard sees no jail time News: Study gives recommendations on how ABQ Ride can improve safety on buses It's a plan to make riding the Albuquerque city buses safer for transit workers and riders. In 2023 Albuquerque City Council adopted an ordinance requiring ABQ Ride to conduct a study that would create a long-term plan to improve safety, after noting a rise in safety threats on buses. 'They are prone to physical assault, verbal assault, general harassment, poor hygienic conditions on the bus,' said David Pennington, Vice President for Parametrix Consulting. The study from the consulting firm Parametrix looked at over 10,000 incident records to create a list of recommendations. One of the suggestions was to create a process that deploys officers or other first responders more quickly to an incident. 'There's multiple agencies or multiple city departments involved in transit security, but whenever you have multiple agencies involved, who is accountable isn't always very clear, and so one group may think another is responding,' said Pennington. The study also found ABQ Ride needs a division to keep track of those incidents. 'There were some years back in 2019, 2018, where there was no data collected at all, so this study really highlighted the fact that data is a very important part to having a strong robust security program,' said Sisneros. Another recommendation was to triple the number of transit safety officers who patrol the transit corridors. The Albuquerque Police Department said having more TSOs will free up more sworn officers. 'Because transit safety officers are able to respond to certain calls for service, they're responding to calls for service that sworn resources don't have to any longer,' said APD Commander Gerard Bartlett. ABQ Ride said they're confident this long-term plan will be successful. 'We've taken our time, we've done the research, we're identifying what's really needed and what's missing, but we're setting it up in a place so that when society changes, they can make the tweaks and the changes they need, but the whole plan stays the same,' said Sisneros. ABQ Ride said they have decided to increase the number of TSOs to 87 once the plan is fully implemented. ABQ Ride says the study cost $500,000. Copyright 2025 Nexstar Media, Inc. All rights reserved.
