Chemical Spill at University

A building on the University of Minnesota campus was evacuated Wednesday after a chemical spill which interrupted traffic flow for about two hours, police said.
Two students spilled the chemical pyridine on the seventh floor of the Phillips Wangensteen building around 6 p.m. and about eight fire trucks and a HAZMAT crew were dispatched to the scene, the Minnesota Daily said.
The hallway of the lab was contaminated which made the cleanup more difficult, the Pioneer Press said.
The sixth, seventh, and eighth floors of the building were evacuated and two blocks of Harvard Street Southeast were closed, according to the Minnesota Daily.
The two students were hospitalized to check for chemical inhalation, the Pioneer Press said.
