The players
Phoenix Fire Department
This municipal agency provides fire protection and emergency medical services to the city of Phoenix.
National Weather Service
This federal agency is responsible for issuing weather forecasts, warnings, and hazardous weather information.
The details
Firefighters utilize a cold water immersion system involving ice bags to treat patients in the field, which reduces core body temperatures by five to six degrees during ambulance transport. Crews frequently rotate units across the city to manage the high volume of simultaneous heat-related and mountain trail rescue calls.
