Three Birmingham firefighters were injured while battling a blaze Tuesday night in Norwood.

Birmingham Fire and Rescue Service responded at 8:18 p.m. to the fire in the 3800 block of Norwood Boulevard. When firefighters arrived on the scene, said Battalion Chief Sebastian Carrillo, heavy fire was showing at the house.

A second alarm was struck because of the manpower needed to fight the fire. About an hour into the blaze, firefighters went to the exterior rear of the home to try to get inside. It was then the roof collapsed, falling off the side of the house and onto fire firefighters.

At least one firefighter was taken away on a stretcher. Another limped to an ambulance. The injured firefighters were taken to UAB Hospital. Carrillo later said all three were listed in stable condition with minor injuries.

The house was under renovation and no one was currently living there. The fire was under control by 11 p.m. Authorities have not determined how the fire started.
