UPDATE: Dropped beakers led to chemical spill at UI's Beckman Institute

UPDATE, 3:30 p.m.:

URBANA — One person was taken to a hospital as a precaution after a chemical spill Monday at the Beckman Institute on the University of Illinois campus.

Around 12:30 p.m., Urbana Fire Marshal Phil Edwards said, first responders were told that a man was moving beakers in a laboratory when some of them fell out of the bottom of the box they were in.

That caused some liquid Nitrobenzene to spill. The skin irritant is hazardous when inhaled, Edwards said.

Edwards said it's not known whether any Nitrobenzene came in contact with the man's skin.

Beckman was off-limits for close to three hours Monday, the first day of the spring semester. At 3:24 p.m., the campus announced in an Illini Alert that "the emergency has ended," declaring it "safe to resume regular activities and to re-enter the building."
