Chattanooga firefighters responded to 3202 Curtis Street on a residential house fire Sunday morning around 6:20. 

Investigators tell Channel 3 that 54-year-old Steven Adams was asleep in a different room when he was awakened by heavy smoke from the front bedroom. 

He saw the mattress was on fire and he closed the door to keep the fire from spreading.  

Firefighters entered the home through the front door, extinguish the fire in the first bedroom and also removed a portion of the ceiling in the bedroom to check for fire extensions, using a thermal imaging camera. 

No injuries were reported.

The wiring was damaged so EPB had to remove the meter to the house. Volunteers with the American Red Cross of Southeast Tennessee responded to the scene to provide assistance to Mr. Adams.

Fire investigators tell Channel 3, the cause of the fire appears to be accidental, most likely from a mattress being placed too close to a wall heater.

Firefighters with Quint 10, Quint 6 and Engine 15 assisted Engine 4 on this fire.
