A possible chemical spill in Clippinger Hall at Ohio University today evacuates the building and sends on person to the hospital.
Ohio University Police Chief Andrew Powers says there were two people working in a lab this afternoon when they became overcome by something and passed out.
One was transported to the hospital and the other refused treatment.
Athens fire, the Environmental Health and Safety and Ohio University Police Department were on scene.
The building was evacutated around 3:30 P.M. this afternoon and reopened around 5:30 P.M.
"Our environmental experts have evaluated the air levels and atmospheric conditions in the building and they couldn't find anything. We had the experts here from facilities management that understand the air handling system and how that works and we couldn't find any reason to believe the building wasn't safe for occupancy," said Chief Powers.
Classes resumed in the building at 6 P.M.
