New Ulm Firefighters were called out to the Medallion Cabinetry plant on the west end of town Thursday night after multiple fires within the building’s exhaust system triggered an alarm. The call came in at approximately 10pm Thursday. The plant’s exhaust system removes sawdust from the production lines and blows the debris into containers outside the plant. The fires were reportedly under control a little over an hour after crews arrived on the scene. A firefighter was hospitalized for treatment of minor injuries. The cause of the fire remains under investigation.
