SECTION 1.2 Pre-use Inspection & Selection

1.2 PRE-USE INSPECTION & SELECTION

To ensure that a scaffold is assembled in a manner that prevents its component parts from
being accidentally displaced at any time, it is important that the following checks are carried
out:

• Ensure that all necessary components and safety equipment are available and
operational.

• Each component should be visually inspected prior to use and should be free from
defects.

• Steel components should be straight with no sign of corrosion, cracks or splits that
would impair strength or safety.

• Deck locks should be in good working order; hooks should be free of cracks and
corrosion, and bolts should be tight and locking nuts tted.

• Stiles or Ply inserts should not be punctured or worn to a degree that would impair

strength or safety.

Damaged or incorrect components must not be used.

Pre-use inspection should ONLY be carried out by a competent person.

standard congurations,

and consideration should be given to providing additional (minimum) training beforehand, if
required.

Ensure that all necessary components and safety equipment are available and operational.

Inspect components for signs of damage or incorrect functioning prior to use. Damaged or
incorrect components should not be used.

Erect Exclusion Zone and t Warning Signs to comply with current legislation.

Before assembling the scaffold structure, check that the location for the structure does not
present any hazards during assembly, dismantling, moving and safe working with respect to
ground conditions, level and slope and obstructions.

Ensure the scaffolding is to be assembled on suitable foundations capable of withstanding
the loads imposed by the scaffolding and, where appropriate, adequate base boards to be
provided.

Fit toeboards on all working platforms.

DO NOT afx sheeting of any type to the scaffold structure without a proper Design.

Turner OCTO® System Scaffolding is compatible and can be used with another similar type
of system scaffold; however, both types have different load bearing capacities. When the
components of both types are mixed, then the load bearing capacities of the compatible product
should be used instead of the data for Turner OCTO® System.

SECTION 1.4 Safety Information

1.4.2 GuardAid

®

(i) User Instructions

The GuardAid® Positional Tool (Figure 1) provides the scaffolder with integrated safety and
safe systems of work throughout scaffold assembly, dismantle and alteration; therefore,
eliminating the risk of fall from height and enabling compliance with current legislation.

GuardAid® is a scaffold tool used to position, while holding secure, a scaffolding guardrail,

before it is xed and locked into place.

GuardAid® enables existing components to be utilised as integral advance guardrails. This
is achieved by combining a sequence of steps; holding, securing, guiding and then enabling

automatic positioning, xing and locking the existing scaffold component.

To use the GuardAid® Positional Tool safely, each guardrail
component can be lifted into position by two operatives (one
at each end of the guardrail - as illustrated opposite).

The GuardAid

®

Positional Tool consists of various component
parts within the Tool Head (Detail ‘A’) that have different
functions for the scaffolder using the tool.

Standard Cup Hook

Should the scaffold standards be slightly off the plumb then one
operative should locate one end of the guardrail into position
and locate in cups allowing wedge to drop and become loosely
engaged. This operative can then assist in locating the opposite
end of guardrail by using the Standard cup hook (of the GuardAid®
Tool) pulling the standard to the vertical (Figure 3); therefore,

allowing the guardrail to be tted correctly.

SECTION 1.5 Assembly Procedures

1.5 ASSEMBLY PROCEDURES FOR TURNER OCTO® SYSTEM SCAFFOLDS

Read this section in conjunction with Section 1.4.1 General Safety Notes on Page 11.

Prior to the commencement of any scaffolding operations appropriate training is recommended.
Forward planning and organisation to ensure the amount and best utilisation of the correct
materials, before assembly procedures commence, will be rewarded throughout assembly

and in the nal scaffold constructed. Careful consideration of the scaffold to be assembled

is required to ensure that it will meet working requirements and is designed to carry the
necessary loads.

The scaffold and the system of work chosen to assemble, dismantle and alter it, must also
comply with the requirements of current legislation, and further ensure that members of the
public are not put at risk.

It is necessary to erect Exclusion Zones and t Warning Signs prior to scaffold assembly.

Ensure the scaffolding is to be assembled on suitable foundations capable of withstanding
the loads imposed by the scaffolding and, where appropriate, adequate base boards to be
provided.

Where the foundation is a soft ground, the soil should be excavated to a rm base or,

alternatively, a larger base board used.

On sloping ground, steps should be cut to ensure the base boards lie at and level.

All components, including GuardAid® components (if used), should be available and
operational.

All components should be closely inspected before use (see Section 1.2 Pre-Use Inspection
& Selection page 5).

Ties should be xed as the scaffold rises (see Tie Pattern on Page 55).

Suitable access should also be used to achieve safe assembly and dismantling at all times.

This Assembly Guide should be issued to all operatives that will assemble, dismantle or alter
Turner OCTO® scaffolds and referred to if required.

Where this symbol appears, a risk of fall is present. However, this is only
applicable if using fall arrest equipment (does not apply when using GuardAid®
methodology to provide collective protection measures).

(iv) Inspection & Maintenance Guidance Notes for Mobile Structures

All mobile structures should be inspected prior to any moves to determine the integrity of the
structures has not been compromised. All components should be securely fastened.

Upon completion of your operations, all tools, materials, debris, etc. should be removed
and all platforms left in this condition. Before usage of structure and prior to structure being
moved, all platforms should be checked to ensure that they are free of any loose items.

All personnel should be clear of structure prior to movement of that structure. However, if
it has been determined by the person in charge that it will be necessary to have personnel
on board the structure to assist in the safe passage of the structure then the following is
necessary:-

i. Check with Turner OCTO® Design Dept. to ensure that personnel can be positioned on

board the structure.

If Item (i) has been afrmed then temporary guardrails have to be placed in position to

protect those on board when the structure is moved.

It is absolutely necessary to ensure that brake locks are in the off position during all
movements of the structure to avoid unnecessary damage occurring to the Castor wheel

and Jack arrangements or “at spots” appearing on the wheel.

When the structure has been successfully moved to its required location, and is stationary,
all brake locks must be on.

Protruding items are potentially hazardous and may cause injury to personnel or damage to
surrounding areas. To prevent such incidents occurring all protrusions should be removed, if
possible, or protective measures deployed before movement of structure.

If structure is to be stored outside, said structure should be adjoined to other such structures
in storage area to add stability and suitable anchorage / ties utilised to prevent overturn
or movement due to prevailing weather conditions. Deck locks should be on and further
supplemented by other means such as cable ties especially if exposed conditions are
expected.

When structure is stored and not in use, access to the structure should be restricted by any
means necessary at all access points on all structure.

Due to the complexity of any freestanding structure i.e. whether a structure is to be
sheeted or netted; if there is enough space to provide a full buttress, will the structure be
exposed to wind or other such important factors, then the structure may require additional
stability measures (ballast) to be employed and should therefore be designed prior to any

There are many variations in the design and construction of hanging scaffolds. The following

instructions are intended as an example only of one type based on the nal design of the

hanging structure.

All hanging scaffolds are subject to design and verication of that design prior to scaffolding

works commencing.

Note When constructing a hanging scaffold structure you MUST pin the standards using
high tensile M16 Nuts and Bolts.

1. Assemble the tower structure using
additional Base Jacks upturned in the
Standards that can then be adjusted

to t tight against the underside of the

1.5.8 Pre Scaffold Handover Inspection

The scaffold should be visually inspected to make certain that all components used have
been installed correctly and secured to prevent accidental displacement.

Check that all necessary scaffold ties (if required) have been installed in accordance with

the tie pattern on page 55 and that all Guardrails and Toeboards have been tted to the

working platforms.

1.5.9 Maintenance

®

All Turner OCTO

Scaffolds, in common with all types of scaffolding, should be regularly

inspected (at least once per week) and recorded, in accordance with current legislation.

The statutory regulations of each state or country should be observed and/ or the type of
work to be carried out on the scaffolding or the environment in which the scaffolding is to be
used, or the position (if moved) may also determine the frequency of inspections required.

However, it is good safety practice to inspect the structure before every working shift and
any defects or misuse reported and corrected, as soon as possible, by a competent person.

Examples of misuse are as follows (but not limited to):

• Overloading of platforms

• Removal of Components; in particular, decking, guardrails, toeboards and ties

• Undermining of foundations

• Sheeting xed to structure without approval

• Electrical Hazards

1.5.10 Dismantling Procedure

The dismantling procedure should simply be a reversal of the steps explained for the

assembly of the various types of standard congurations.

However, several safety procedural steps should be considered before dismantling
operations begin.

1. Refer to your Risk Assessment – a separate Risk Assessment should be carried out
prior to any dismantling operations.

2. Visually check the scaffold from ground level for any obvious hazards that may have
developed or been created (by the user) that may not be listed on the Risk Assessment.

Such hazards may include:

• Debris left on the scaffold

• Overhead wires on or touching the scaffold

• Obvious removal of scaffold ties (check number of ties tted on Hand Over Certicate to

assist in determining whether ties may have been removed).

• Removal of structurally important components, e.g. Decks and Bracing Guardrails.

This list is not exhaustive and other hazards may exist. If in any doubt and you can see

hazards that have not been notied on the Risk Assessment, seek consultation before

proceeding to the next step.

3. Erect an exclusion zone and t Warning signs in accordance with current legislation
prior to scaffold dismantle taking place.

4. Commence dismantling operations and continue to visually inspect scaffold at close
proximity throughout the dismantling procedure for any unforeseen hazards.

Every standard to be tied at top lift except where platform is greater than 1500mm from eaves.

• End ties to be tied at maximum 4000mm crs

• All ties to be within 300mm of standard - transom joint

• Good practice is to x all ties to inner and outer standards. A minimum requirement is for all end ties to be xed to

inner and outer standards and other ties xed to inner standard only.

SECTION 1.7 Maximum Heights

The following examples of Unclad Tied Wall Scaffolds are SYSTEM CONFIGURATIONS in

accordance with BS EN 12810-1:2003 (7.2 The standard set of system congurations).

They note the maximum computed leg load for the congurations built to their maximum

height to top platform level. Where this computed height is higher than 24m it is noted that
the Max. Height to Platform is 24.0m.

LIVE LOAD

The loading congurations are in accordance with BS EN 12811-1:2003(6.1.3 Load

Classes).
See Turner Fabrication interpretation of Load Class Table below.
