MADISON, Wis. -- A building on the University of Wisconsin-Madison campus was evacuated Friday afternoon after several gallons of chemicals were spilled.

The Madison Fire Department responded at 3:48 p.m. Friday to a report of a chemical spill on the 12th floor of the Engineering Research Building, which is located across from Engineering Hall.

"The chemists heard a 'pop,' and they left the room and evacuated. Nobody was injured," said Bernadette Galvez, spokeswoman for the Madison Fire Department.

Crews evacuated the building when they arrived at the scene.

The Hazardous Material Team was called in and found that several containers of nitric acid, hydrofluoric acid, hydrochloric acid, acetic acid and ammonia were spilled. Several half-gallon containers of acetic acid and ammonia were spilled.

The Madison Fire Department turned the incident over to UW Safety, which has the ability to clean up this type of incident.

Authorities said no one was injured and that everyone was allowed to return to the building Friday evening.
