Fire destroyed a garage on Miller Drive along with four cars inside for a total damage estimate of more than $150,000.
Barrie firefighters were called to the home at 10 p.m. Thursday after flames erupted in the garage while a man and woman were working on a car up on a hydraulic lift.
"There must have been some flammable vapours that ignited because they heard whoosh sounds and the man's coat was on fire," said Samantha Hoffmann of Barrie Fire and Emergency Service. "The woman used her hands to pat down the coat which is how she burned her hands and he had burn marks on his feet."
Hoffmann says the burns were minor and both were treated in hospital and released.
The blaze is not suspicious according to fire investigators, who were unable to enter the structure because it was too unstable.
"It's lucky it was a detached garage," said Hoffmann. "Also lucky the nearest house was all brick because the heat from the fire cracked two of the windows in the closest home but because it was all brick it didn't spread to the house."
There have been twelve fire fatalities in ten days in Ontario, Hoffmann noted.
"December is the worst time of the year," said Hoffmann. "It's easy to get distracted and busy. Alcohol can also be a factor."
