At 10:16 PM firefighters in Division 3 were dispatched to 265 Clinton Ave for a working structure fire in a 3.5 story wood frame multiple family dwelling. Engine 79 was first to arrive on scene. Upon arrival, fire was observed on the first floor with heavy smoke pushing from the second and third floors on the "A" side of the building. Both exposure buildings on the "B" side and "D" side were also compromised due to the close proximity. Once Deputy Chief 3 Matthew Jordan arrived, he requested a 2nd Alarm to the scene. Engine 23's crew stretched a second line from Engine 79 to the second floor once they arrived. While Truck 23 was searching the first floor, Truck 83 began venting. Conditions however quickly deteriorated. Deputy Chief Jordan then ordered all firefighters to evacuate the structure immediately. As firefighters were exiting, a partial building collapse occurred. The front of the structure collapsed on to 6 firefighters who were in front of the building. A 3rd Alarm was then requested as firefighters rescued their injured comrades and attempted to bring the flames under control before flames spread to surrounding buildings. Multiple master streams and hoses were then placed in operation. The 6 injured firefighters were quickly rescued and then transported to Mattropolis University Medical Center. As flames extended into the "C" exposure and damaged the "B" exposure, it took firefighters over 2 hours to bring the flames under control. Thankfully all occupants of the structure were able to escape the building unharmed. Four of the injured firefighters suffered minor injuries. One firefighter suffered broken ribs and minor burns, and one firefighter suffered severe burns to his face and broken ribs. All are listed in stable condition. All units that operated on the scene were Engines 79, 23, 88, 59, 83, 34, 52, 85, 38, 54, Trucks 23, 83, 52, 25, 3, Rescue 3, Battalions 15, 11, 12 and Division 3.
