Around 1530, crews on the north side of the county were alerted for an apartment fire with possible entrapment in the 5000 block of 85th Avenue, Co.28’s first due. Initial crews arrived on scene to find a 3 in the front, 4 in the rear garden style apartment with smoke showing and the working fire was sounded. Shortly after the working fire dispatch, it was noted that the fire was now in the attic and roof area. Command requested the second alarm to be sounded to bring in additional companies. Truck 37 was enroute to transfer to Co, 33 when they were added to the box on the 2nd alarm. Truck 37 arrived as the second truck on the second alarm and was told to bring personnel to the command post. Shortly after arriving to the command post, the evacuation tones were sounded to transition to a ladder pipe operation. Due to a poor water supply, ladder pipes were unable to start flowing. Groups were then assigned for each building, a truck company and engine company per building involved. Truck Co.37 was assigned to Exposure D to open up on the top floor. Crews encountered triple layered drywall while opening up. Fire was found in the attic space of the exposure which was extinguished by the engine company. Truck 37 was then instructed to set up the ladder pipe to assist with defense operations. Prior to getting the ladder pipe in service a mayday was called by a FF on the third floor. A 35 foot ladder was thrown to retrieve that fire fighter. Evacuation tones were again sounded clearing all personnel from the building. Ladder pipe operations were completed by three ladder companies knocking down a bulk of the fire. Ladder pipes were shut down and the interior crew was instructed to head back in and open up to find any hotspots. The truck crew was able to locate and rescue three dogs that were trapped in their respective apartments, all dogs were returned to their owners. Truck 37 operated for nearly 4 hours returning to service.
