A structured approach to controlling hazards, in descending order of effectiveness:
1. Elimination – Remove the hazard entirely (e.g., fix leaks and remove mould-infested materials).
2. Substitution – Replace the hazard with something less harmful (often less applicable for mould).
3. Engineering Controls – Modify the workplace to reduce exposure (e.g., improve ventilation).
4. Administrative Controls – Change work procedures or rosters to minimize exposure.
5. PPE – Use personal protective equipment as a last resort.
