This from Eric Haak:

I took in three fires on Wednesday and got to all three of them late.  I decided to send in a few images from each in honor of everyone who has to work outside in these conditions.  The first image is from the still & box on the 1500 block of Kostner.  It must have really been going as the entire face of the building was covered with soot.  A dog was rescued from this fire as seen in the third image.
The third and fourth images were taken on the 9100 block of South Crandon which was another still & box.
The last image is of Engine 38 with their second fire of the day on the 1400 block of South Ridgeway.
