Laval University laboratory fire forces evacuation

A minor accident in a laboratory at Laval University in Quebec City forced the evacuation of the Pouliot Pavillion this afternoon.

A university spokesperson says the fire started when liquid metal came into contact with flammable material in a metallurgy lab.

When 30 firefighters arrived at the scene, security guards were fighting the blaze with fire extinguishers.

After determining that the chemical fire could be safely extinguished with water, firefighters finished the job.

Approximately 3,000 people had to leave the campus. 

The university says there were no injuries.

The evacuation order was lifted around 3:15 p.m., roughly one hour after the fire began.

Investigators from Quebec's Commissariat des incendies are still trying determine the exact cause of the incident.
