How to do it

  1. Stay calm and dial 911; in other countries use the local emergency number.
  2. Say the address, including apartment number, cross street, highway mile marker or a landmark.
  3. Say what happened in one sentence, such as a man has collapsed and is not breathing.
  4. Say how many people are hurt and any danger such as fire, gas, traffic or a weapon.
  5. Answer every question and follow the instructions, which may include CPR coaching.
  6. Stay on the line until the dispatcher says you can hang up.
  7. Send someone to meet the ambulance, unlock the door and turn on outside lights.
  8. Learn your home and work addresses by heart, and check your phone's emergency location settings.

Common mistakes

  • Starting with the story instead of the location.
  • Hanging up before the dispatcher is finished.
  • Assuming someone else has already called.
  • Relying on your phone to send an exact location, which it may not.
