The Chattanooga Fire Department on Thursday responded to a fire at Metalcasting Minerals Technologies at 3406 Alton Park Blvd. with five fire companies.
Battalion Chief Ashley May said a hopper was full of combustible materials and a small area was on fire. Firefighters opened the hopper's hatch and applied large amounts of water and foam to the burning coal dust-type material.
Firefighters remained on the scene for a lengthy time. No injuries were reported.
Battalion Chief Ashley May said there was minimal damage to the hopper.
The plant was shut down during and after the fire. Information on how the fire impacted production at the company was not available. The cause of the fire will most likely be ruled accidental.
