  • the death of a significant number of people
  • serious injury that needs immediate treatment in hospital for a significant number of people
  • a permanent or irreversible disabling condition to a significant number of people

Safety occurrences include both:

  • an incident that has happened
  • the risk of an incident happening in the future

You must do this even if the safety occurrence is remedied immediately.
