It's an incredible sight. Firefighters covered in ice working to extinguish an enormous blaze in a warehouse in below-freezing temperatures.
One-third of Chicago's firefighters - more than 200 - were called to the fire after it broke out on January 23, according to US fire department officials.
As they fought the blaze, the water from the firefighters' hoses turned to ice and encased the building.

Chicago fire department spokesman Larry Langford told NBC Chicago the department had not had a fire that big in "many years".
The former furniture warehouse, on the corner of 37th Street and Ashland Avenue in the Bridgeport neighbourhood on the city's South Side, was now ''one big block of ice’’, ABC Chicago reported.
ABC Chicago said the flames from the fire ''could be seen for miles''. One firefighter sustained injuries during the battle to contain the blaze, NBC Chicago reported, and was taken to hospital with a minor back injury.

Chicago resident Mike Lopez told WXOW the fire was ‘‘pretty hot, you know, intense".
‘‘And then this morning, now I look, and it looks like an ice castle," he said.
The fire broke out in below-freezing temperatures as an Arctic blast grips the US midwest and northeast, with at least three deaths linked to the frigid weather, making some locations feel as cold as -46 degrees.
