Figure 12 Installing ceiling or upper level floor joists 8.3 Guarding openings All stairwells, atriums and voids through which a person could fall must be sturdily guarded, covered with an industrial safety net or sheeted over, regardless of the fall distance from the upper level floor. Guardrailing should be provided in accordance with Section 4.1 of this Code. In particular, toeboards should be fitted to prevent tools and materials from being kicked into the void. Voids and atriums must be guarded as soon as possible after laying sheet flooring, as illustrated in Figure 13. a person working from a stepladder or a working platform such as a trestle scaffold or similar, may fall over the guardrail and through the opening, the opening must be covered with temporary flooring, timber sheeting, an industrial safety net or similar, even if guardrails have been erected around it. Any coverings or temporary floors and their supports must be of robust construction capable of withstanding impact loads from any potential falls. Figure 13 Void at upper level guarded 8.4 Wall framing Once sheet flooring has been laid and openings have been guarded, work on wall framing may commence. Where the potential fall height for persons constructing or erecting wall frames is 2 metres or more, edge protection should be provided. Window or door openings in external wall frames should be fitted with guardrails prior to raising the frame (see Figure 14). All braces and fixings should be prepared prior to raising the frames. Access to the floor should be restricted to those workers erecting the wall frames. Figure 14 Erecting upper level wall frames 8.5 Installing prefabricated roof trusses This section provides guidance on safe working procedures for the installation of prefabricated roof trusses. Preparing for roof erection Where practicable, roof trusses should be placed by crane on the wall top plates at the time of delivery. The truss erector, supplier and transporter should liaise to confirm the order in which the trusses are to be loaded onto the truck. Where possible, the trusses should be able to be unloaded at the site in the order that minimises the amount of handling by the truss erectors. When working at height, the erectors should be able to access the next required truss from the top of the truss stack. Before commencing work, ensure that all work areas have safe paths of access and egress at all times and are free of obstructions.
