Upon arrival St. John's Regional Fire Department crews were met with an abundance of smoke throughout the home.
The source of smoke was determined to be from a furnace backfire.
A home care worker for one of the residents of the home — in the basement apartment — said from across the street that he went to the home to report to work and noticed "quite a haze of smoke" in the house.
He was able to get his client safely out of the home.
A dog was also safely removed from the home.
HSC paramedics checked over the tenant of the apartment but deemed her to be okay.
There was quite a bit of soot about the interior of the house.
She could be observed with "sooty hands" as she said she went in the home upstairs to rescue Jack, an Italian mastiff dog from the home.
She wanted to go back inside to get her cat, which was looking out from the ledge of a window in the basement apartment.
A relative was there calling out to another cat Charlie.
No injuries were sustained in the incident, which is now under investigation by the RNC.
