Carleton University has evacuated a number of buildings on its campus after reports of smoke coming from a chemistry building.

The school sent an email alert to students and faculty Saturday evening, warning of a ``hazard on campus.''

A post on the school's website says Ottawa fire services are investigating reports of smoke at the Steacie Building for Chemistry.

It says the Steacie, Health Sciences and Richcraft buildings are being evacuated as a precaution.
