At 11:39hrs Battalion 21 and Truck 21 went on the MCFRS Box Alarm for the townhome fire in the 3400 block of Springhill Dr. Upon arrival of Battalion 21 fire was evident from the exterior porch area of an end of row townhome with auto-extension to Division 2. Initial fire attack was made on the seat of the fire as crews progressed inside to limit extension which was between the 1st and 2nd Division as well as in the attic space. With fire running multiple void spaces and eventually through the roof, command placed Ladder 36’s ladder pipe into service. Upon achieving a knockdown on the fire crews reentered to check for further extension and complete overhaul.
