Importance Levels – Summary

1. Low risk: non-habitable

2. Most residential, commercial and industrial buildings,

(including until recently, most school buildings)

3. Large concentrations of people, special purpose

infrastructure (and all new state school buildings)

4. Hospitals and emergency services, essential

infrastructure

5. High risk special purpose
