Fire crews secure potentially hazardous materials at KU’s Haworth Hall

Firefighters from Lawrence Douglas County Fire & Medical investigate a report of a chemical spill inside Kansas University's Haworth Hall Thursday, Aug. 26, 2010. Crews were on the scene about 7 a.m. and evacuated the building for more than an hour. The building reopened in time for 9:30 classes.

Kansas University’s Haworth Hall was briefly evacuated Thursday morning after an accidental chemical spill.

University officials said a custodian apparently knocked over some canisters in the building’s basement. A HazMat team was dispatched to the building at 1200 Sunnyside Ave. around 7:30 a.m., and determined the chemicals were nontoxic.

Sunnyside Avenue was closed for about an hour between Illinois Street and Naismith Drive on Thursday morning while the scene was being investigated.

After the substance was identified, the building reopened around 8:30 a.m., and classes after 9:30 were held as scheduled.
