ST. CLOUD — A fire prompted a brief evacuation at a St. Cloud manufacturing company.

WestRock production manager Allen Mackedanz said that staff noticed flames at the base of an exhaust fan on the building’s roof after the facility lost power for about 10 minutes on Thursday morning, according to a press release.

He said no one was hurt, and employees later returned to work.

WestRock manufactures and supplies paper and packaging materials.
