Capt. Brian Hutchinson of the city's fire department says the incident happened on Thursday when a glass tube, likely a small test tube, containing a mixture of nitric acid and methanol failed.
He says none of the injuries were reported to be serious at the time, but the patient was taken by ambulance on a "routine" dispatch, which means without lights and sirens.
Hutchinson says the incident drew the city's full hazardous-materials team, which includes 16 members from two fire halls.
He says the team has responded to the university in the past, when other chemicals or elements have been spilled.
