Encountering a scene (First at the scene)

You may be the first officer at a scene that you encounter in your duties.

  1. Think first of safety:
    • don't get into a situation that you can't get out of
    • wait for backup help if you need it
  2. Assess the situation and plan your actions before you enter the scene.
  3. Plan how to withdraw if necessary.
  4. Notify the dispatcher of the situation and describe:
    • where the situation is, the address
    • who is involved
    • what the situation is
    • the car and licence plate, if appropriate
  5. Request the backup you need:
    • emergency services
    • special units
    • supervisor
  6. Continue to reassess the situation and adjust your plans as you enter the scene.
