Morehead State University had a chemical spill in one of its classrooms.
No one got hurt and the school says no one was in danger.
However, the entire second floor of the Lloyd Cassity Classroom Building was closed Wednesday.
They have a hazardous waste disposal crew evaluating the building and working on the cleanup.
As of Wednesday morning, they still didn't know what the chemical was.
The Department of Industrial and Engineering Technology and the Institute for Public Policy are located there.
