Figure 1: Diagrammatic illustration of erection and dismantling using various erection platform options — one-man operation. Note: scaffold is shown against a building, so guardrails only needed on external face. Toeboards omitted for clarity. Figure 2: Diagrammatic illustration of erection and dismantling using various erection platform options — two-man operation.
Note: Scaffold is shown against a building, so guardrails only needed on external face. Figure 3: Diagrammatic illustration of an erection platform option for a five-plank-wide scaffold. Note: Scaffold is shown against an existing building, so guardrails only needed on external face. Access ladder and toeboards omitted for clarity.

Note: Toeboards and lower mid-rails omitted for clarity. Note: Proprietary temporary edge protection systems such as that illustrated above require a safe work method statement and the scaffolders to undertake training to use the system safely.
The permitted scaffold configurations are intended to assist those erecting less complex scaffolds to do so without having the structural capacity of their scaffolds checked by an engineer. Table 1 applies to all scaffolds that fit within the below design assumptions. For scaffolds with greater structural capacity or that otherwise do not comply with the design assumptions, a revised version of table 1 may be developed based on an engineering review of the specific scaffold system. Common issues where engineering review is required due to non-compliance with the design assumptions are:.
Variations to the above design assumptions will require a detailed structural analysis by a structural engineer with a sound knowledge of scaffolding. Check that the installed scaffold conforms to the design assumptions before using the information in the table below.

Working platforms of various duty ratings may be provided at various levels so long as the platforms within any bay comply with a row from table 1. Figure 6a shows an example of how different duty loads or closed platforms may be applied along the run of the platform. The full run of the platform does not have to be classified as a working or closed platform.

The following checklist can be used by a person in control of preparing for the erection, alteration and dismantling of a scaffold to ensure the important safety features and procedures specified in this guide are in place.

Tick yes or no as appropriate against each item. Are there 10 or less available hop-up brackets capable of supporting platforms? Are the hop-up brackets suitable for no more than two planks about mm width? Is live load uniformly distributed over the working platform — and not exceeding permissible duty rating as outlined in table 1?
Are the number of fully planked platforms and hop-up platforms, and their associated duty ratings, in accordance with table 1? Are working platforms supported by hop-up brackets not loaded to more than light duty, regardless of the duty rating of the working platform in the adjoining scaffold bay? Is scaffold containment sheeting eg chain wire mesh and shade cloth , if provided, at least 20 per cent porous? Has every second standard been tied to a supporting structure of adequate strength at maximum 4 m vertical intervals? For scaffolds greater than 14 m in height to the top working platform, is an extra row of ties fitted near the base of the scaffold, as shown in figure 6?
Are standards with containment sheeting attached extending no more than 2 m above the highest ties? For standards supporting sheeting, are all the joints below the top working platform? Are ties staggered, as far as reasonably practicable? Have joints in the standards been staggered, as far as reasonably practicable? Is the foundation or footing adequate to support the imposed load? Note: If in doubt, get expert advice. Does the site-specific induction include the names of all persons responsible for implementing control measures in relation to scaffolding?
The versatility of tube and coupler scaffolds means they can be assembled in a wide variety of different configurations. This also means erecting tube and coupler scaffolds can be complex when compared to prefabricated scaffolds. It can include modular, tower, cantilever, hung and suspended swing-stage scaffolds and must be design registered as required under Part 1 of Schedule 5 to the model WHS Regulations.

SWA is not a regulator and cannot advise you about scaffolds or scaffolding compliance. If you need help, please contact your work health and safety authority. You must check with your WHS regulator if a model Code of Practice has been implemented in your jurisdiction. Check with your WHS Regulator. This site is undergoing constant refinement.

Under the model WHS Act , the scaffold is classified as a structure. Regulations relating to structures and plant both apply to the scaffold. Under the model WHS Act , these individual components are classified as plant. Under the model WHS Regulations , much scaffolding work is classified as high risk and must be carried out by someone who holds the appropriate class of high-risk work licence. Work health and safety duties Everyone in the workplace has work health and safety duties. Managing risks You should manage risks by following a systematic process of: Identifying hazards—find out what could go wrong and what could cause harm.
Assessing risks if necessary—understand the nature of the harm each hazard could cause, how serious the harm could be and the likelihood of it happening. Controlling risks—implement the most effective control measures that are reasonably practicable in the circumstances.
Reviewing control measures to ensure they are working as planned. Find out what could cause harm When it comes to scaffolding, the following can help you identify potential hazards : Walk around the workplace to identify areas where scaffolds are used or scaffolding work is performed and where there is interaction with vehicles, pedestrians and fixed structures.
Look at the environment in which the scaffold is to be used including checking ground conditions. Identify the major functional requirements of the scaffold like the maximum live and dead loads and access requirements. Inspect the scaffolding before and after use. Ask your workers about any problems they encounter or anticipate at your workplace when constructing or interacting with scaffolds and scaffolding work—consider operation, inspection, maintenance, repair, transport and storage requirements. Inspect the erected scaffold. Review your incident and injury records including near misses.
Take action to control the risk For risks it is not reasonably practicable to completely eliminate, consider the following options in the order they appear below to minimise risks , so far as is reasonably practicable: Substitute the hazard for something safer, for example using mechanical aids like cranes, hoists, pallet jacks or trolleys to move equipment and materials wherever possible instead of manually lifting scaffolding. Isolate the hazard from people, for example install concrete barriers to separate pedestrians and powered mobile plant from scaffolds to minimise the risk of collision.
