(Hannibal, Mo)--Hannibal firefighters respond to a report of smoke coming from a 2-story home at 323 North 6th Street Wednesday afternoon.

The call came in at 2:19 p.m.  Crews arrived to find smoke coming from the eaves.  Assistant Fire Chief Jeff Frame says firefighters gained access to the attic through the stairwell leading to the second floor. They discovered insulation smoldering and burning in the attic. Within 30 minutes the fire was contained and extinguished. Crews cut two holes in the roof and ventilated the attic area. They also removed most of the smoldering insulation.

A total of 11 firefighters responded to the scene. One firefighter suffered an arm injury and was taken to a doctor for treatment.  Fire personnel remained on the scene until 5 p.m., completing salvage and overhaul operations.

Fire investigators have determined the cause was accidental--electrical in nature.

The occupants of the home escaped without injury.  Officials say the home did not have a working smoke detector at the time of the fire.

The structure sustained light smoke damage throughout and moderate to light fire damage in the attic.
