Firefighters Battle Huge Warehouse Fire in Chicago in Less than 0 Degree Temps

From NBC:

No injuries were reported in a Friday morning warehouse fire on Chicago's northwest side.

The fire, on the 1945 N. Latrobe Ave., was in a warehouse used by Advanced On-Site Concrete Inc.

It took a little more than an hour for crews to extinguish the fire. At one point, the roof of the one-story structure collapsed as firefighters doused it with three streams of water.

Caution was taken because firefighters were advised the building contained propane tanks.
