Was passing by Eng. 18's house when Bat. 4 and Eng. 18 were responding to the fire. I got there about 5 minutes after the still companies. Fire was on the 3rd and 4th floors, and Eng. 18 used there deck gun on both floors to darken it down initially. Two extra trucks were called in because squad 1 was at the 2-11 on Kedzie. This was a Eng 23, Tower 5 still but they were at the 2-11 also. Companies here were Eng. 18, 28, Trucks, 8,4,7,2, Bat. 4,1, 271, and 213 showed up also.
