This from Erik Haak:

At 1631hrs on Friday afternoon, the Englewood Fire Alarm Office dispatched a working fire response to 1650 W. 75th Place.  At 1634hrs, Truck 50 confirmed a working fire in a 50×100 1-story ordinary commercial structure.  Truck 50 reported a possible truss roof and almost immediately called for the Still & Box.  Battalion 20 set up defensive operations with Engine 129 operating in sector 1 and Tower Ladder 39 setting up in a lot to the east of the fire building.  Squad 5’s snorkle operated on the parkway to the east of the building as well.  At 1656hrs, 2-2-5 pulled a 2-11.  Tower Ladder 34 was set up to the west of the fire building at the end of Paulina Street.  The first photo taken in my series was shot nearly an hour after the fire started.  The 2-11 was struck out at 1821hrs and companies stayed on scene chasing hot spots until just before 2000hrs.
