The Duluth fire department responded to a call at the Duluth Entertainment Convention Center on Tuesday night. Assistant Fire Chief Chris Martinson says crews arrived to smoke in the lower part of the DECC. It turned out to be just a small fire in a garbage can down in the wood shop. Martinson says it isn’t clear yet what started, but added that a sprinkler did get set off and that’s what extinguished the fire. There was no damage, just water on the floor to be mopped up.
