Firefighters spent Thursday afternoon putting out a fire at a propane plant in Marshfield.
About 10,000 small propane tanks caught fire at Kosan Crisplant, formerly known as Pinnacle Propane.
The plant was sold to Kosan Crisplant in 2020.
Three workers inside escaped.
Rescue crews treated one worker for injuries.
KY3 reports the fire caused the propane tanks to explode into the air.
Authorities are looking into the cause.
Smoke could be seen around the area, including in Springfield.
