Firefighters are not just dealing with the heat outside but also the heat from their suits and from fires.
Firefighters were working to beat the heat by setting up cooling stations that include misting fans, ice packs and extra water.
"Your body temperature can easily rise three or four degrees when you're in there, even if you're in there a minute or two," Columbus fire Battalion Chief Michael Fowler said. "Then we come out here, and it's probably 90 degrees out here right now. It's supposed to get to 100 days."
Firefighters also said that they were keeping an eye on each other to check for signs of heat exhaustion.
