A section of the Novelis plant in Fairmont is closed temporarily after a fire.
The Fairmont Fire Department said it happened early Sunday morning.
The facility's Cardox CO2 System put the mill fire out right away, but it did spread up into the large chimney system.
Firefighters said the flames were seen from East Park Avenue.
The outside of the building sustained moderate damage.
The cause of the fire is unknown at this time, but it's not believed to be suspicious.
Everyone made it out of the building safely.
