The University of Minnesota’s Smith Hall was evacuated Wednesday after a chemical spill at about 2:50 p.m.

No injuries have been reported. The building is expected to be open as usual Thursday morning.

According to University reports, the spill occurred during a class and amounted to 12 liters of chemicals including acetone, mineral oil, methanol and carbon disulfide.

Concerns arose more from the combination of chemicals than from the size of the spill, University police Lt. Troy Buhta said. University police, the Department of Environmental Health and Safety and the Minneapolis Fire Department responded to the spill.

University spokesman Chuck Tombarge said cleanup will take between three and four hours and will be conducted by Bay West, a private company located in St. Paul. The University has a contract with Bay West for this purpose, but costs may vary by event.
