Dramatic video shows a group of firefighters racing to get down this roof as flames overcome the downtown Phoenix home.
"While the ladder company was exiting the roof, a large volume of fire coming out of the hole they had cut as well as side of the roof and one of our firefighters sustained an injury," said Mike Billingsley, a Captain with the Phoenix Fire Department.
The firefighters were trying to ventilate the building for crews working below.
"Because the interior crews were getting so much material falling down on them, they decided to go with a defensive operation and evacuate [the] building," Billingsley said.
The ladder company was still on the roof as the flames leaped from the home. You can see the firefighters scrambling to get down in time.
One of the firefighters suffered a burn and fell to the ground.
The firefighter was taken to a local hospital with a minor burn injury. The two other firefighters made it down the ladder safely.
The woman living inside the burning home was also taken to the hospital. Firefighters rescued her from the flames just moments before.
"Her son, [who] she was worried about still being in the house was already out of the house," Billingsley said.
The landlord told Fox 10 that the mother and son have lived in this home for 30 years. You can see their belonging in piles covered in ashes.
"After they removed the lady and got it all clear on the structure to make sure nobody else needed to be rescued, the fire was… the conditions were changing very quickly," Billingsley said.
Tonight, we're told the resident and the firefighter are expected to be ok. Now investigators are trying to determine what sparked the early morning blaze.
The Phoenix Fire Department has not released the injured firefighter's name, but we are told he is a long-time member of the department. He is expected to be released from the hospital by tomorrow morning.
