The Chicago Fire Department Englewood Fire Alarm Office received multiple calls for a fire at 57th and Peoria around 11:30 PM (5/15/16). Englewood FAO started in a working fire response. Engine 50 arrived first in and reported they had a 2-story, ordinary, vacant 25×50 with heavy fire on two and in the rear. Squad 5 then called Battalion 6 who was still en route to the scene, and advised that the heavy fire was now getting into the Side D exposure, which was a similarly-constructed building. Battalion 6 requested a Still & Box as companies pulled out to go defensive. Four lines were led out on an exterior attack. Truck 51 was moved from Side A for Tower 39 to take the front and utilize their aerial master stream. Companies on scene: E50 E84 E116 E54 T51 T18 TL39 BN6 Sq5 2-7-4 RIT BN19 T20 BN5 BN15 2-2-1 A1 A49 4-5-5 4-5-8.
