For the second time in less than 24 hours, Calgary firefighters have responded to a house fire in the southwest.

Saturday afternoon, fire crews battled a blaze in the community of Shawnessy.

The fire broke out at around 1:30 p.m. at a home in the 100 block of Shawinigan Dr. S.W.

The flames were intense and the presence of heavy smoke prompted firefighters to call a second alarm.

The homes on either side of the burning building were evacuated.

The lone occupant inside the burning home escaped unharmed but attempted to go back inside.

Acting Battalion Chief Steve Wilson says the woman’s plan to re-enter the house was a poor decision.

“It's not a great move at all. Once you get out, it’s a good idea just to stay out,” says Wilson.  “There are so many unknown dangers if you go back inside especially if you’re not prepared and are without the proper equipment.”  

“Leave that to the firefighters on the scene.”

The neighbouring homes suffered minor exterior damage in the blaze.

An investigation into the cause of the blaze is underway.

On Friday evening, a home on Everstone Blvd. S.W. was destroyed by fire. No one was injured in either fire.
