NORMAL — Illinois State University’s Bone Student Center was closed and evacuated Tuesday night following a fire in the exhaust system for the Burger King restaurant.

About 200 people were inside when smoke was seen about 9:45 p.m., and all got out safely, ISU spokesman Jay Groves said. Firefighters turned the building back over to ISU officials about 11:30 p.m. and left the scene about midnight.

All of the building except Burger King will be open as usual today, Groves said.

A student working at the information kiosk in the first-floor concourse saw smoke coming from the Old Main Room around 9:45 p.m., and the fire alarm panel indicated a problem in Burger King, which is on the second floor, Groves said.

Normal Fire Department Public Information Officer Matt Swaney said the fire was contained to the ductwork leading from the restaurant to the roof, and there was moderate water and light smoke damage, mostly in the Burger King area. He said the source of the fire was the grill or the exhaust hood.

Most of the occupants were attending a pre-spring break entertainment event in the Brown Ballroom or practicing dances for an upcoming March Madness fundraiser, Groves said.
