B/C-10 had heavy fire in a 2 story Mattress wharehouse. The bldg was irregular shaped approx 100 x 200. Fire fighters started an interior attack, but had extreme difficulty due to bldg construction being all brick with no windows for ventilation. B/C-10 requested the 2nd alarm and shortly afterwards evacuated the bldg due to an interior collapse. Crews then set up for an exterior attack. An exterior wall had 2 large collapses which also punched out a hole in a side wall, giving them better access to the fire. Numerous master streams and ladder pipes were in service. 1 F/F was transported with minor injuries, reported to be glass in the eye.

I caught the 2 collapses, they start at pic numbers 41 & 62.
