Firefighters responded just before 9 a.m. to the home in the 4200 block of Groveland Avenue, in the city's West Arlington neighborhood, and found heavy smoke, said Chief Kevin Cartwright, a department spokesman.
One firefighter, while fighting the flames, fell through the flooring of the first floor into the basement, sustaining a non-life-threatening laceration across his nose, Cartwright said. The firefighter was transported to Mercy Medical Center’s Public Safety Infirmary.
The fire was brought under control about 9:45 a.m., Cartwright said.
The home had "a lot of debris inside" and it was unclear whether anyone was living there, Cartwright said.
Douglas Lent, a spokesman for the American Red Cross, said one person was displaced and is being assisted by Red Cross volunteers.
