Chicago firefighters had their hands full already battling a huge warehouse fire in the city's South Side Tuesday night. But imagine trying to spray water on a blaze when temperatures are closer to 0 than freezing.
The temperature was 10 degrees during the fire, part of an arctic outbreak gripping much of the upper Midwest.. Water was freezing to hoses, hydrants -- even the firefighters' uniforms.
And the next morning when the sun came up, it revealed an entire block coated in a thick ice leftover from the firefighting efforts.
The high Wednesday was only 23 and temperatures dropped even further to 4 degrees Wednedsay night, meaning that ice wasn't going anywhere anytime soon.
Firefighters were concerned the weight of the ice could collapse the damaged building -- adding even more to their challenges.
It's probably enough to make a few firefighters think of moving to sunnier climates. Or, at least some place where the spray doesn't freeze on contact!
