The Nature of Shared Workplaces and Overlapping Duties
Under section 34 of HSWA, a PCBU with overlapping duties must, so far as is reasonably practicable, consult, cooperate, and coordinate activities with every other PCBU with whom it shares duties [source: launch-source-09]. This requirement prevents organisations from disclaiming responsibility by pointing to another entity's presence on site.
Supply Chains, Contractors, and Upstream Entities
Furthermore, upstream PCBUs within the supply chain carry distinct obligations under sections 39 to 43 of HSWA [source: launch-source-09]. Upstream entities include designers, manufacturers, suppliers, importers, installers, constructors, and commissioners [source: launch-source-09]. These entities must ensure, so far as is reasonably practicable, that the work they perform or the materials, equipment, or structures they provide to other workplaces do not generate health and safety risks [source: launch-source-09]. When combined with section 34, upstream providers and contracting PCBUs must coordinate to prevent hazards from emerging downstream [source: launch-source-09].
