The Calgary Fire Department had its hands full with two overnight fires, one in a home in Renfrew and the other on a deck in Marlborough.

Crews were called to the first scene, in the 1400 block of Remington Road N.E., and found a large volume of smoke coming out of the home.

They worked hard to keep the flames from getting to the roof of the house.

Four residents all got out safely, but they won't be allowed to go back for some time.

The second fire, also in northeast Calgary, broke out on the back deck of a Marborough home at about 2 a.m.

Officials say that a neighbour had spotted the fire and then alerted the residents, who were all able to escape from the fire without any injury.

Once crews arrived at the scene, they were able to quickly knock down the fire.

Fire officials say that the home did have a smoke alarm, but it was not functioning at the time the fire broke out. They remind Calgarians about the importance of functioning detectors as they are proven to save lives.

The fire investigator is working on the cause of both blazes.
