An Invercargill family can thank working smoke alarms for saving their lives after a fire broke out in their home on Monday night.
A fire communications spokesman says an electrical fault caused the blaze in a garage attached to their house on Tweed St just before 1am.

He says firefighters had just been attending a fire in a house on Beaumont St, where another family was also lucky to escape.
The Beaumont St blaze broke out in the roof cavity of their home just after 10pm on Monday evening, and was upgraded to a second alarm with four fire trucks attending.
The cause of the fire is unknown and being investigated, but is not being treated as suspicious.
Meanwhile, a firefighter was treated for minor injuries after a blaze in the Bay of Plenty.
It started just after midnight in a commercial building behind the Murupara shopping centre.
It was "well involved" when they arrived, with six fire trucks sent to battle the blaze.
The cause of the fire is being looked at by both police and a fire investigator.
