FORT WAYNE, Ind. (www.incnow.tv) -- For people whose jobs force them to be outside, conditions like Tuesday's can actually be dangerous.
Not only do firefighters have to work outside, they have to do it while they're soaking wet.
That can cause problems for the gear they wear, and the gear they use to put out a fire at your house.
One of the biggest problems they face is the possibility of the air tanks on their backs freezing because they're breathing warm air out, but the metal canisters are exposed to the cold.
So commanders rotate the crews as often as they can.
"Usually we'll ask the crew and we'll say, 'are you okay, you okay?' And mostly they'll say, 'yes, we are.' You know, we just have to use that administrative pressure then and say, 'okay, you've been out this long, time to recycle,'" says Fort Wayne Fire Department Assistant Chief Ron Privett.
The number one problem, nation-wide, in these conditions is firefighter slips and falls on frozen sidewalks, streets and driveways.
That's why the drivers of the fire trucks are in charge of spreading materials around to help with traction.
