The obligation
PCBUs must apply a hierarchy of controls — ground-level work, solid construction, fall prevention device, work positioning, then fall arrest — to manage fall risk so far as is reasonably practicable.
A PCBU must, so far as is reasonably practicable: (1) ensure work involving fall risk is carried out on the ground or solid construction; (2) provide safe means of access and egress; (3) where a fall risk remains, minimise it by providing a fall prevention device (e.g. edge protection, guardrails), then a work positioning system, then a fall arrest system. This hierarchy mirrors the WHS Regulations and the code's five-level control structure.
