The smell of natural gas forced the evacuation of a dining hall at the University of New Brunswick this weekend. Fire crews were called to the university campus in Fredericton after receiving a call about a gas-like odour. A platoon captain with the Fredericton Fire Department says gas detectors didn’t pick up any substantial readings. Mike Mizner says the source of the scent is still under investigation, but it may be a problem with the kitchen’s deep fryers.
