Excerpts from nbchchicago.com:
The Chicago Fire Department says it is taking steps to prepare for scorching-hot temperatures in the city, activating additional resources to keep residents and firefighters safe.
All fire calls received by dispatchers on Wednesday and Thursday will automatically be elevated to ensure that there are adequate crews on scene, to ensure plenty of rest and recuperation for firefighters on a scene.
More ambulances will be activated during the heat wave to help respond to heat-related issues in the city.
Finally, fire officials offered tips for residents to stay safe, including asking children not to play in fire hydrant spray, as it could pose safety concerns for the children and for passing motorists.
Residents are also urged to call 311 if they need information on cooling centers, or if they need to request well-being checks for neighbors.
