Still & Box Alarm in Chicago, 2-11-17 (part 1)

This message comes from Eric Haak:

Here are some photos from a still and box alarm that took place at a warehouse in Chicago on Saturday morning, February 11th. The 15th Battalion was the first to arrive and reported light smoke coming from a 600 x 200, four-story, fire-resistive warehouse. Seven minutes later, they reported heavy smoke inside and requested a box unit. It turned out to be an auto fire, and the Mobile Ventilation Unit (MVU) was brought in to clear the smoke. These images capture the scene as it unfolded.
