From temperatures in the 50s to now the 80s can be a real shock to the system. It's a welcome shock for a lot of us, but for firefighters it can be dangerous.
Fighting fires in 90-degree heat and in heavy gear can spell trouble for firefighters. Now they have a new tool designed to help them keep their cool.

"Bunker gear is sort of like an oven mit, where just like if you go to pull a cookie sheet out of the oven, if you leave your hand in there long enough, it will begin to sweat," says Captain Kyle Ohashi with the Kent Fire Department.
Fighting a housefire last night, Kent firefighters couldn't do it alone. The helpers in this case also needed help.
"Now we have King County paramedics who come out to the scene with us to make sure firefighters get rehydrated and hook them up to a heart monitor if necessary," he added.
