Previous stories about Clairton Coke Works

TribLive wrote a lengthy story in 2019 about safety at Clairton Coke Works and air pollution. On Dec. 24, 2018, a gas-fueled fire tore through the plant’s No. 2 Control Room, burning for about two hours and twisting 10-inch beams that supported the roof. Critical equipment used to clean coke oven gas was damaged and pollution control systems were shut down.

The 2018 fire prompted the TribLive investigation.

TribLive has also kept track with fines against Clairton Coke Works.

Other accidents
