The Knoxville Fire Department is reminding everyone to be careful using space heaters as temperatures are dropping after they determine that’s the cause of a West Knoxville house fire.

Crews called to the 3300 block of Keith Avenue Saturday morning and found the home completely in flames and it has been determined a total loss.

Fortunately, no injuries were reported. Two men and a woman living in the home are being helped by the Red Cross.

KFD says you should keep space heaters at least 3 feet away from flammable materials and never leave them unattended.

Also, plug heaters directly into an outlet not into extension cords.

The home did not have any working smoke alarms.
