If your power is out, here are some tips:

  • Use flashlights for emergency lighting
  • Keep refrigerator and freezer doors closed.
  • Put on layers of warm clothing if it is cold outside.
  • Never burn charcoal for heating or cooking indoors. Never use your oven as a source of heat.
  • If the power may be out for a prolonged period, plan to go to another location (the home of a relative or friend, or a public facility) that has heat to keep warm.
