Fire Commissioner Jose Santiago said when the first crews arrived and began heading up the stairs, a stairway collapsed as crews were climbing up to the third floor, trapping one firefighter who was quickly rescued.

That firefighter suffered a minor shoulder injury, and was taken to Presence St. Francis Hospital in Evanston.

In all, eight firefighters were injured at the scene. Some were hurt in the stair collapse, and others were hurt falling on ice at the scene. ALl the injuries were minor.

Santiago said frozen hydrants at the scene hampered efforts to put out the fire. While most were opened after using steam to thaw the hydrants, at least one was still frozen more than an hour after the fire started.
