to the intersection of a putlog and the building or structure.
Braces should be a minimum of F8 unseasoned hardwood or MGP 12 seasoned pine with cross-sectional dimensions not less than:
    * 75 mm x 38 mm for a scaffold supporting a light duty working platform, and
    * 100 mm x 50 mm for a scaffold supporting a medium duty or heavy duty working platform.

2.8 Stability
Every scaffold must be effectively stabilised by tying to the building or an adjacent structure, or by rakers to the ground. Ties and rakers should comply with the following:
    * Except in single pole scaffolds, ties should be fixed to both standards.
    * Rakers should be of the same material as the standards, fixed to the outer standards and, at ground level, they should be firmly footed or fixed with timber stakes driven into the ground, and positioned at approximately 45 degrees to the horizontal.
    * The first level of ties or rakers should not be higher than 4 metres above the lowest soleplate.
    * The distance between longitudinally adjacent ties or rakers should not exceed two bays.
    * Ties should not be fixed to the cladding of a building or structure.
    * Ties and rakers should be positioned so as not to obstruct access along the working platform.

    * No more than one lift should be constructed above the highest level of ties or rakers.
    * The minimum cross-sectional dimensions of ties should be the same as for braces.
    * Ties and rakers should be continuous in their length.

2.9 Splicing of members
Where members are spliced, such joints should be butt joints with fishplates of the same cross-sectional dimensions fixed equidistant on each side of the butt point, and bolted through with four 12 mm diameter mild steel bolts, washers and nuts, spaced at 225 mm centres.

2.10 Working platform edge protection and access
Working platforms must be provided with edge protection and a safe means of access and egress. Further guidance is available in AS/NZS 4576.

B3: TIMBER SCAFFOLDS – SINGLE POLE WITH HIGH FIRST LIFT HEIGHT
This section provides guidance for single pole scaffolds with:
    * a first lift height of up to 6 metres
    * a maximum load rating of medium duty
These scaffolds are typically suitable for many work tasks in the construction of double storey
extensions, including the fixing of cladding, general carpentry, rendering and painting. Scaffolds described in this section are not suitable for heavy duty works such as bricklaying.

3.1 Configuration
The configuration of scaffolds described in this section is shown in Figure 26.
For scaffolds erected in accordance with this section, the primary loads are transferred directly from the working platform to the
