Firefighters battling a different kind of heat

SOUTH BEND, Ind. -- Firefighters face a different kind of battle when the temperatures rise into the 90's.

While fighting fires is stressful enough, the heat makes it dangerous for the men and women in the fire department when they go out on fire calls.

To help keep their bodies cool firefighters wear special vests. In addition, firefighters are rotated out on a much tighter rotation.
