Three people were displaced from their east-side home Thursday because of a fire that also sent one firefighter to a hospital. At about 4 p.m., multiple 911 calls reported a house fire in the 6700 block of East Stella Road, said Capt. Barrett Baker, a Tucson Fire Department spokesman. The neighborhood is east of South Wilmot Road and south of East Golf Links Road. The callers were reporting flames and smoke coming from the roof and from the back of the house. Firefighters pulled a hose line through the front door and were trying to work their way to the back of the house to put out the fire, said Baker. He said the residents were not in the house. An electrical line hanging from a pole in the alley to the house caused a safety concern, and firefighters needed to avoid the backyard, Baker said. A Tucson Electric Power Co. crew was called in to shutdown power to the line. Firefighters battling the blaze inside the home had little to no visibility and had to back out of the house temporarily because of the conditions. A hole cut into the roof allowed smoke to escape from inside the home and improved visibility, allowing firefighters to enter the house and put out the remaining flames, said Baker. He said 23 firefighters brought the fire under control in 37 minutes after arriving on scene. One firefighter was taken to a hospital for precautionary measures related to exhaustion, said Baker. The Southern Arizona Chapter of the American Red Cross assisted the family — a woman in her 70s, and a man and woman in their 50s. Investigators do not know the cause of the fire, which started in the rear of the home. A damage estimate was undetermined.
