At about 6:30 p.m. Centre County 9-1-1 received a call from a Penn State lab technician in the building, who reported a strong, unknown odor in the building. Emergency responders included Penn State’s Hazmat unit, Penn State Police, ambulances, Centre County EMS, Alpha Fire Co., and Penn State Environmental Health and Safety.
The Hazmat team went through the building, searching all rooms and labs, with instruments that can detect volatile chemicals. No source of the odor could be found until a student reported using an adhesive fixative spray in a building stairwell. Officials opened a roof hatch and put a fan in the stairwell to clear the odor from the stairwell. As Hazmat officials continued to monitor the air, they reported levels of the odor dropped.
