The obligation
Duty holders must apply the hierarchy of controls to eliminate or minimise risks so far as is reasonably practicable.
The Code mandates use of the hierarchy of controls in descending order: (1) eliminate the hazard; (2) substitute, isolate, or engineer controls; (3) administrative controls; (4) personal protective equipment (PPE). Higher-order controls are preferred. PPE is the least preferred measure and must not be the sole control unless all higher-order measures are not reasonably practicable. Combinations of controls are encouraged. The chosen controls must be documented.
