5 Risk Management Scaffolding is classified as high risk work requiring ongoing hazard identification with the assurance of effective controls to ensure a safe working environment is maintained. Scaffold work includes, but not limited to, the risk of:

• falling to a lower level; • structure collapse or tipping; or • dropped objects.

The risk management approach used by CPM is outlined in DR001941 CPM Risk

Assessment Procedure through hazard identification, assessment of the risk(s) and the implementation and management of preventative controls shall be the benchmark for all personnel working on site. The different stages of managing scaffolding risks comprise of the following:

• safe design and planning; • assembly/erection; • use and maintenance; or • disassembling.

Hazards such as rotating equipment, uncompacted earth, ditches, debris, high-tension wires, and other hazardous conditions created by other activities, the work and/or natural environment i.e. strong winds, storms or close proximity lightning, must be considered.

Scaffolders shall survey the work area for additional hazards before erection begins and shall be included in the JHEA’s and/or permits with the control methods to mitigate risks. As a minimum all scaffolding work shall require a risk assessment in the form of a CPM approved JHEA or Safe Work Instruction (SWI). Additional risk assessment in the form of a Task Based Risk Assessment (TBRA) may be requested by CPM if deemed necessary.

A Permit to Work (PTW) is required when the risk assessment identifies isolations are required. Where isolations are unnecessary, a JHEA and Working at Heights Checklist is sufficient.

NOTE: Departments may enforce a higher standard, requiring a PTW to be raised prior to work commencing. Scaffold Supervisor(s) are to ensure compliance with the relevant Area Manager or their delegate prior to the commencement of work.

Proximity or obstruction to live electrical equipment, emergency utilities and exits, firefighting equipment, valve handles, and other critical equipment is an important consideration during pre-starts, risk assessments and permit preparation.




L\333622132.1

6 Scaffold Requirements 6.1 General Safety

Scaffolds are temporary structures which are specifically erected to support access or working platforms and shall comply with legislative requirements and Australian Standards AS/NZS 1576 series and AS/NZS 4576. To ensure the safety of all personnel working on or with scaffolds and their components, the following minimum requirements shall be complied with:

• scaffolds should be designed by a Competent Person, e.g. someone who holds a relevant scaffolding HRW licence;

• alternative design plans for scaffolds that are not mentioned in the AS/NZS 1676series are to be subject to Scaffold Design Approval by a Competent Person, such as a Qualified Engineer experienced in structural design prior to the scaffold being used;

• where doubt exists about the adequacy of the supporting structure, it should be assessed by a Competent Person, such as a Qualified Engineer;

• all scaffolds shall be erected, modified, maintained and dismantled by personnel who hold a National or State certificate of competency, HRW licence;

• all scaffolds shall be built on solid foundations;

• scaffolds shall be anchored and braced to prevent swaying, tipping or collapsing;

• safe access and egress;

• scaffolds shall not be loaded in excess of the working load for which they are intended;

• exclusion zones are established to prevent vehicle / plant contact with the structure;

• personnel shall be fit for duty to erect, work on and dismantle scaffold. If there is any condition or medication consumed that may affect their ability to work safely, they shall inform their Supervisor immediately;

• personnel shall, before accessing any scaffold, clean mud build-up from work boots to prevent slipping;

• all scaffolds must have durable ScaffTag clearly visible and secured at every access point indicating:

- Load capacity - Work location - Date erected - Inspection date - Person who erected the scaffold - Inspectors’ name




L\333622132.1

• prior to commencing work on any scaffold, personnel shall visually inspect the scaffolding and ScaffTag. Personnel shall also verify that access ladders, hand-rails, toe-boards, decking, and screens are in place and that the scaffold is safe to work on;

• no person is to climb over handrails of scaffold;

• the erection, dismantling, alteration, modification and inspection of scaffolds shall only be carried out by, or under the direct supervision of an Advanced Licenced Scaffolder. The normal ScaffTag Inspection system, thirty (30) days maximum, applies to these scaffolds.

• modifications to scaffolds or their components which may impose additional loads or alter the maximum working load limit shall be assessed and approved by a Qualified Engineer experienced in structural design;

• mix-matching of scaffold components is prohibited;

• electrical leads to be used on scaffolds shall be inspected to ensure no wiring faults are present to energise the scaffold. Metallic ties are not permitted for securing leads to the scaffold;

• scaffolds must be separated from overhead power lines and electrical apparatuses. Uninsulated scaffold must display "DO NOT USE WHERE ELECTRICAL HAZARDS EXISTS" in the largest lettering practicable;

• all erected scaffolds are recorded in a scaffold register in accordance with AS/NZS 4576;

• scaffold deemed unsafe shall be tagged "out of service", supervisor notified and access points barricaded to prevent entry.

6.2 Design The scaffold design shall consider the scope of work to be performed and the most appropriate scaffold system and installation. The different types of scaffolds utilised on site include:

• engineer designed;

• Suspended Scaffold;

• mobile scaffold;

• Pre-fabricated Scaffold; and

• tank scaffold.

The structure(s), components and connections must comply with design requirements for strength, stability and serviceability and take into account influence of eccentricities and the most adverse combination of actions (or loads) that may exceed the maximum WLL potentially compromising the integrity of the scaffold structure, components and the safety of personnel working on or within




L\333622132.1

the vicinity of the scaffold. Designs shall detail the duty rating and include the self-weight (or dead-load).

The use of the term ‘actions’ are known as ‘loads’ within this procedure and derives from AS/NZS 1576.1:2019, describing three (3) types:

• Permanent actions;

• Imposed (duty) actions; and

• Environmental actions.

Table 1 – Action Types

The design requirements for scaffold strength is to limit the stress on the structure based on potential modes of structural failure. Consideration is given to the combination of factored loads producing the most adverse effect on the scaffold or components or both as per AS/NZS 1170 series.

Designs shall prevent the instability of scaffolding from upturning, uplift and sliding as per AS/NZS 1170.0, except where a combination of loads provide net stabilising effect.

Serviceability requirements for components used on scaffolds shall comply with AS/NZS 1576.1 clause 2.5.3.2. This is to ensure components are in a functioning condition and do not affect the intended use of the scaffold. Factors that may adversely affect the serviceability include, but not limited to deflection, vibration, durability and clearance.

Action Type Description Includes

Permanent Relate to the weight of the structure and its components

• platforms (working, closed, catch or access)

• ladders and stairways • screens and containment sheeting • brackets, ropes and tie assemblies • other attachments i.e. electrical cables and

hoists etc. Imposed Also known as ‘duty’.

Temporary loads that are introduced to the scaffold

• personnel • tools / equipment • materials and debris • impact(s) to the structure

Environmental Loads imposed due to the physical or natural environment

• storms • high winds • rain • close proximity lightning • eathquakes • atmospheres (i.e. corrosive)




L\333622132.1

6.2.1 System Design The system design encompasses the fundamental components to be mated into the connecting structural arrangements. It shall take into account the following:

• the supporting structure(s) strength, stability and rigidity;

• edge protection;

• handling and usage frequency of components;

• safety of personnel undertaking erection, alteration, access, use, dismantling and working within the vicinity of scaffolds;

• environmental factors (weather, atmospheres etc.); and

• duration of the scaffold,

in accordance with the applicable Australian Standards.

There shall be documented evidence that analysis and/or testing of the scaffold system design, components and connections has been conducted by limit state or permissible stress procedures and has factored the most adverse combinations for permanent, imposed and environmental loads.

Appendix 1 provides a flowchart for assessing structural design of scaffolds as per AS/NZS1576.1.

6.2.2 Installation Design

Installation design shall take into account all anticipated loads or component-imposed loads for all platform levels at their most adverse position and intended use of the scaffold. Refer to AS/NZS 1576.1 clause 2.6 Installation design.

NOTE: Imposed load combinations will vary and is dependent on the type of work being performed.

All imposed loads are required to be reviewed and adjusted to ensure the scaffold bay load bearing capacity is not exceeded. Categories of imposed loads within each scaffold bay including landings at every level must be determined detailing the distribution of imposed loads between platforms which will influence the length and width of the platform required. Duty ratings include:

• Heavy duty;

• Medium duty; and

• Light duty.

Structures that require other load ratings or where the design arrangement is not included with the scaffold equipment, must be structurally engineered and approved by a Qualified Engineer prior to erection. This requirement excludes overhead protection which as a minimum must be erected to the light duty rating of 225kgs.

Anchorage and tie-assemblies shall be assessed and certified as fit for use by a Qualified Engineer. The arrangement shall ensure it provides stability and take into account the strength of the tie assembly and supporting structure. The location of anchor / ties shall not obstruct any access along the working platform or access way.

6.3 Materials The scaffold structure and its component members and connections, including all materials used, shall satisfy the design and operational requirements for strength, stability and serviceability in accordance with the applicable Australian Standards and this procedure.

All materials used on scaffolds shall comply with the applicable Australian Standards which may include:
