A chemical spill at the Civil Engineering building at the University of Arizona has caused a classroom evacuation.
According to Barrett Baker with the Tucson Fire Department, a student in a laboratory noticed the spill and pulled the fire alarm.
Everyone was evacuated safely and no injuries have been reported.
Authorities are still at the scene working to determine what chemicals were spilled and how to properly dispose of them.
The roads surrounding the building were closed but have since reopened.
