The obligation
Where risks cannot be eliminated, PCBUs must minimise them using the hierarchy of control measures and keep those controls effective and under review.
If eliminating a risk is not reasonably practicable, the PCBU must minimise it by substitution, isolation or engineering controls, whichever is most appropriate and effective. Any remaining risk must be minimised by administrative controls, then by ensuring suitable personal protective equipment is provided and used. Control measures must be maintained so they remain effective, fit for purpose and suitable for the nature and duration of the work.
