A sprinkler system is being credited for saving an Indiana Wood Products Plant.
The fire was in one building that made wood products. Crews say it appears as though equipment caught fire.
The fire department could see flames through the roof when they got there. Fire sprinklers prohibited the fire from spreading to other buildings.
"If they didn't have a sprinkler system, it probably would have burned down. That's what saved the building - that early control of the fire, to let it get beyond the fully involved stage," Middlebury Fire Chief Jeff Wogoman said.
Crews knocked out the roof fire first, and then went inside the building to tackle that fire.
Chief Wogoman said, "I figured we'd have a beast on our hands, but it went pretty smooth."
