An overheated electrical light fitting triggered the evacuation of Huddersfield’s Queensgate Market Hall after a fire.
Andy Wooler, Watch Commander at Huddersfield Fire Station, said an off duty nurse acted quickly when she spotted the fitting had set fire to ceiling tiles in the roof of a unit at the hall.
He said she broke the ‘break glass’ point in an alarm at the disused shop unit at around 11am.
Staff left their shops and shoppers were told to leave the hall and others were stopped from entering the hall from entrances in The Piazza, Peel Street and Alfred Street.
Fire crews from Huddersfield were called to reports of smoke coming from an electrical light fitting.
Crews checked the hall for further problems.
Mr Wooler said the initial fire was dealt with by a market worker with a fire extinguisher before crews arrived.
He said it had burnt some of the ceiling tiles in one of the units.
