Kansas University students wait outside Malott Hall around 10:30 a.m. Wednesday, Nov. 16, 2011, after the building was evacuated following reports of a chemical spill. No spill was found, and students were readmitted shortly after 11 a.m.

Malott Hall, which houses Kansas University’s chemistry department, was evacuated Wednesday morning after reports of a possible chemical spill.

University spokeswoman Jill Jess said someone reported the possible spill about 10 a.m. Emergency crews from Lawrence-Douglas County Fire Medical and KU’s Environmental Health and Safety were on the scene. The building was evacuated because of an “abundance of caution,” Jess said.

Students and faculty were readmitted shortly after 11. Jess said the likely source of the smell was sealant applied to the floors earlier this week.
