Heat health emergency

The City issues different types of heat alerts, depending on the weather. During very hot weather, the City may declare a heat health emergency.

During a heat health emergency

A heat health emergency activates several City services. In a heat health emergency:

  • A special helpline, called the Heatline, opens for calls. Nurses answer questions about health safety and heat-related illnesses. You can call the Heatline at (215) 765-9040.
  • Cooling centers stay open later. Find your local cooling center.
  • Mobile heat health teams may be dispatched.
  • Residential utility shutoffs stop.

To stay cool during a heat health emergency, visit a cooling centerpool, or sprayground.
