As the clock struck midnight, Kuhl Hose was called to assist Brookside with RIT. Chief 250 arrived, reported a working fire and requested an additional engine from Kuhl Hose.  A 2 car garage was fully involved with fire extension into the residence.  Engine 242 arrived, established water supply and stretched hand lines to the fire in the garage and 2nd floor of the residence.  Upon arrival 683 setup the RIT on the A-B corner and did a 360 walk-around of the structure.  The crew from 682 went inside division 2 to aid in suppression efforts.  687 was returning from an EMS call and also responded as the RIT Ambulance.  The RIT was downsized and part of the crew was put to work with the overhaul on division 2.  Crews returned just before 02:00.  The Fire is under investigation by the Fire Marshal and Brookside Fire Department.
