A Newnan firefighter was injured after crews battled a commercial building fire Monday afternoon. At approximately 3:30 p.m., firefighters were dispatched to 84 Wall Street for a commercial building fire. Upon their arrival, firefighters saw smoke coming from the front and rear of the building. Crews had to gain quick entry to the building and cut a lock on a fence. Members from Engines 1, 3, Rescue 1, Ladder 4, 1205, 1201, and 1217 were quickly on the scene along with 12 other personnel. Crews accessed the building through the front to find heavy smoke with little to no visibility. Fire was found on the second floor which burned through to the first floor catching pallets on fire. The fire was extinguished and the smoke was removed from the structure. One firefighter was sent to the emergency room for a suspected torn bicep muscle, according to Chief Stephen Brown.
