At 2301 hours on MArch 6th, MFD was dispatched under mutual aid to the Walden Fire District with one ladder to the scene of a working structure fire. Car 1 (Pressler) and Truck 221 were quickly on the road and on scene in Walden. They found a 3 story brick apartment / business type structure with fire on all 3 floors. As fire conditions worsened, Walden called additional alarms and equipment to assist in bringing the fire under control. In the end, a 4th alarm and special calls were needed to bring the fire under control. Montgomery’s truck crew laddered the 3rd floor and assisted in fire suppression, search and rescue, and overhaul. Crews operated for several hours in freezing temperatures and heavy smoke and fire conditions to help extinguish the blaze.
