Both news outlets reported that all employees were quickly evacuated without harm, but the fire did cause significant damage to the facility. KSN reported that fire crews were forced to evacuate because of hazardous materials and explosions inside, though no firefighters were hurt.
KSN reported investigators say the fire started in the southeast part of the building, where roof work was being done. They don't know if the roof work is related to the fire. They say there are no indications the fire was suspicious.
