5.13 Completion Tags

All scaffolds shall be conspicuously fitted near the point of access with a Scafftag.

Where multiple access points are provided to a single scaffold each access point to the scaffold shall be fitted with a Scafftag.

The scaffolder shall fix the holder where it is easily seen and protected from damage (it should not be fitted on the access ladder, as ladders (with scafftag inadvertently remaining) may after dismantling of a scaffold be reused on other scaffolds with the scafftag still affixed, thus potentially providing incorrect information on the status of that scaffold). The Scaffolding Inspector, after completing a successful inspection of the scaffold shall fill out the Green Card and scaffolding register. The scaffold information shall be updated on the Scafftag,

 Every 7 days

 Whenever there is a modification of the scaffold  After inspections following severe weather 5.14 Mobile Scaffolds

- All mobile scaffolds shall have their wheels locked when stationary (persons using a mobile scaffold must, before accessing the scaffold, check that the wheels are in the locked position)

- All mobile scaffolds shall be fitted with access ladders secured on the inside of the narrowest section of the scaffold .

- Mobile scaffolds shall be tied off or secured to solid structures whenever practicable.  No persons or materials shall remain on a scaffold that is being moved.

NSRP Complex Project

Title: Scaffold Procedure Contractor Doc. No.

S-000-1654-0400V Page 21 of 34  A mobile scaffold should only be moved by pushing / pulling at the lower level, no force should

be applied to the scaffold at a height from base greater than 1.5 meters (If necessary, taller mobile scaffolds should be partially dismantled to reduce their height and minimise the likelihood of overturning during moving).

 Mobile scaffolds shall be used only on surfaces within 3 degrees of level, and free of pits, holes, and obstructions;

 Wheels shall be securely pinned to the scaffold legs;

 Wheels shall not be used in conjunction with screw jacks, unless they are a manufacturer’s approved device;

 Platforms shall not extend outward beyond the base supports unless outrigger frames are installed to ensure stability;

 All decks shall be fully boarded;

 Load rating for the working platform shall not be exceeded.

 Mobile scaffolds shall be fitted with plan bracing at the foot lift, at every second lift and below the working platform.

5.15 Welded Metal Frame Scaffolds

Frames and accessories for scaffolds shall be maintained in good condition and every defect or unsafe condition shall be corrected before further use. Any broken, bent, excessively rusted, or otherwise structurally damaged frames or accessories shall NOT be used. Defective material shall be returned to the scaffold yard immediately and tagged as defective.

Scaffolds shall be set on a solid foundation that can carry the maximum intended load:  On solid concrete slabs, grid mesh, etc., base plates required;

 On surfaces where there is a possibility of settling, additional support must be used under the base plates. The minimum support acceptable is scaffold planks or plywood of similar dimensions;

 On uneven surfaces, screw jacks must be used to level the scaffold. They are not to exceed 300mm when extended.

All end frames (panels) shall be locked together vertically by pins.

Scaffolds shall be properly braced by cross bracing or diagonal braces, or both, for securing vertical members together laterally. The cross braces shall be of such length that will automatically square and align vertical members so that the erected scaffold is always plumb, square, and rigid.

The frames shall be placed one on top of the other with coupling or stacking pins to provide vertical alignment of the legs.

Horizontal cross braces are to be used when the scaffold is higher than two complete sections. To provide good footing, two planks or manufactured steel decking should be kept below the section being erected. Scaffold boards shall be secured, even if they are used for a short period of time.

Ladder sections shall be installed as frame sections progress. All ladder sections must be well secured. Access to working platforms shall be by ladder, rigidly attached by the erecting crew.

NSRP Complex Project

Title: Scaffold Procedure Contractor Doc. No.

S-000-1654-0400V Page 22 of 34 All scaffold work platforms shall be equipped with guardrails, a mid rail, securely anchored toe boards, and be completely decked with manufactured aluminium scaffold decking, or standard wood planks and infill mesh panels or approved wire mesh.

Prior to starting work on a scaffold, every employee shall visually inspect the scaffold and scafftag and determine that handrails, toe boards, and decking and infill mesh panels/ wire mesh are in place and that the scaffold is safe to work on.

Where the scaffold is deemed unsafe, the scaffold is to be tagged out of service and the supervisor notified.

5.16 Aluminium Scaffolding

Where aluminium scaffolding is considered for use on site, Subcontractor are to provide a comprehensive WMS and Risk Assessment to the CONTRACTOR’S Site HSSE Manager or designee for review and approval a minimum of seven working days prior to the intended use of the scaffold.

No aluminium scaffold shall be erected or used unless approved by the CONTRACTOR Site HSSE Manager. Verification of approval shall be by the name and signature of the CONTRACTOR Site HSSE Manager or designee being provided on the WMS and marked as approved.

6 scaffold control management 6.1 Standards

Scaffolding supplied for the project is to comply with the appropriate International Standard.

6.2 Qualifications and Competency Assessment

Qualification and competency testing of employees involved in the erection, modification and dismantling of scaffolding is to be in accordance with employment and HSSE&S Training Program, Doc. No.: S-000-1654-0210V. In the absence of local/National Vietnam competencies, standards similar to the Australian Standard reference may be used.

accredited course in scaffolding. AS 1576.1

6.3 Risk Assessments

A risk assessment for all planned activities that require working at heights is to be conducted and should consider such factors as,

 The hazards associated with the scope of work  Fatigue (work environmental and social)

 Team members physical and psychological capacity to safely undertake the scope of work  Guarding or isolation requirements when in close proximity to mobile equipment and plant

including vehicles, overhead cranes, powerlines or conveyors; and  Emergency rescue and recovery

Work in the vicinity of operating plant is to be controlled by the Permit to Work System.

6.4 Erection and Dismantling

Where practicable, the erection and dismantling of scaffolding is to be carried out using a sequential method that provides fall prevention for team members.

As a minimum the first 4 lifts (8m from ground/platform level) of a scaffold being erected and the last 4 lifts of a scaffold being dismantled are to be completed using a sequential erection/dismantling method.

Additional weights imposed by adopting a sequential erection/dismantling method are to be considered during the scaffold planning stage.

Where the sequential erection/dismantling method is impractical, a risk analysis is to be conducted to identify the most practical fall prevention method.

As a last resort fall arrest systems (full body harness, lanyard or inertia reel and anchor point) are to be provided where no other protection or prevention measure is practicable. Fall prevention is to be in accordance with the Working at Heights procedure, Doc. No.: S-000-1654-0510V.

6.5 Handover

The Scaffold Supervisor is responsible for ensuring the following before handover of the scaffold to the user:

 Complies with any design drawing and/or specification for that particular scaffold  Complies with the requirements of the standards

 Is adequate for the purpose for which it is intended  Is stable and in a safe condition

 Has been thoroughly inspected and approved by a competent Scaffold Inspector.

 Has a Scafftag attached at all access points to the scaffold as record of its construction and clearly indicates the scaffold is complete and ready for use.

S-000-1654-0400V Page 24 of 34

ATTACHMENT 3: INDEPENDENT TIED SCAFFOLD (COLUMN BOX TIE) 6.6 ATTACHMENT 4: INDEPENDENT SCAFFOLD Scafftag Procedure

The Scafftag system, attachment 7, is to be used exclusively across the site to indicate and record the structural integrity, access and inspection of each scaffold.

Scaffold Under Construction - during construction the Foreman Scaffolder or Competent Scaffolder must fix Scafftag holders (STH) at approved access points to the scaffold, scafftag holder is to be placed in a visible location.

When the scaffold is incomplete or when the first section of scaffold has been erected, the Scafftag holder showing the international prohibition symbol and the script "DO NOT USE SCAFFOLD" will be showing (Refer to attachment 6). The information will apply to all personnel not involved in the scaffold construction. All the Scafftag holders and inserts should be weatherproof.

Construction Complete - When scaffold construction is complete the scaffold is inspected by a Scaffolding Inspector to ensure compliance with Statutory Legislation, Codes of Practice and Project Requirements. If satisfied with the condition of the scaffold the Scaffold Inspector

completes the Green Scafftag, the Scafftag is then placed in the Scafftag holder on the scaffold to indicate that the scaffold is SAFE FOR USE. The Scaffolding Inspector is also responsible for completing the Scaffold Register in respect of the same information on the Scafftag..

The Status Scafftag contains the following data (Refer to attachment 6):

 ? date erected, with name Competent Scaffolder; and initials of Forman Scaffolder;

 ? maximum loading in kN/m2 (See the table below for different types of scaffold and typical loads);

 ? date inspected, with name and initials of Scaffold Inspector;

Note: - All entries onto the tag shall be made with a permanent ink pen. All personnel, who come

in to contact with scaffolding, shall be trained in the use of the scaffold tagging system. It will be the Scaffold Inspector’s responsibility to enter the details and conditions of scaffolds inspected into a Scaffold Inspection Register. (Refer to attachment 7).

Where a scaffold is identified as damaged or defective the green Scafftag card is to be removed and reported to the Scaffolder or Supervisor in control of the scaffold.

Ongoing inspections will need to be carried out every seven days, after adverse weather, or after modification of the scaffold. On satisfactory inspection the Scaffolding Inspector will sign and date the reverse (yellow) side of the Scafftag and update the Scaffold Inspection Register accordingly.

If the scaffold is found unsafe at any time, the Green Scafftag is to be removed from the holder and replaced by the Prohibition Insert "DO NOT USE SCAFFOLD". The Scafftag will remains in that situation until satisfactory remedial works have been carried out and the scaffold is re-inspected and considered "SAFE TO USE", or until the scaffold is dismantled.

6.7 Inspection

Scaffolds are to be inspected weekly by a competent person and the Scafftag and Scaffold Register signed or updated accordingly. Daily inspections shall also be conducted to ensure scaffolds are suitable and safe for use by personnel prior to using them.

NSRP Complex Project

Title: Scaffold Procedure Contractor Doc. No.

S-000-1654-0400V Page 25 of 34 Audits will be performed periodically by HSSE and/or supervision to ensure compliance with scaffold requirements.

6.8 Falling Objects

Where people are required to work or pass under a scaffold, scaffolds are to be provided with wire or synthetic mesh in fill between the toe board and top rail and secured in such a way as to be secure and strong enough to hold expected load requirements. Exclusion zone barricades and warning signs may be substituted for the wire mesh where appropriate.

6.9 Access

Entry and exit from ladders to the various platforms is to be via swing or drop gates unless a risk assessment identifies the risk of failure or fall through a gate is greater than the risk of injury whilst climbing under a fixed rail.

Joints are to be wrapped or otherwise shielded near access ways to prevent injury to passerby.

6.10 Register

A register is to be maintained of all scaffolding erected on site. Each scaffold is to be identified by a unique number and weekly inspections recorded against the relevant scaffold entry.

The register is to be available and accessible at all times.
