Basic Scaffolding Ticket (Australia) Exam Questions & Answers 2026 (21–30)

Question 1

'System scaffolding' (modular scaffold) differs from tube and coupler scaffolding because:

TheoryPractice · Accepted Answer

It uses pre-engineered components with predetermined connection points, offering faster erection and consistent geometry

Question 2

Which component prevents a scaffold from swaying in the plane parallel to the building face?

TheoryPractice · Accepted Answer

Longitudinal (facade) bracing

Question 3

What is the function of 'plan bracing' in scaffolding?

TheoryPractice · Accepted Answer

To resist horizontal forces in the plan (horizontal) plane, preventing racking at each lift level

Question 4

A 'coupler' (clamp) used in tube and coupler scaffolding must be:

TheoryPractice · Accepted Answer

Compliant with AS 1576 and free from visible defects such as cracks, distortion, or damaged threads

Question 5

What is a 'swivel coupler' used for?

TheoryPractice · Accepted Answer

Connecting two tubes at any angle for bracing

Question 6

A 'right-angle coupler' (also called a load-bearing coupler) is used:

TheoryPractice · Accepted Answer

To connect ledgers and transoms to standards at 90°, and transfers load through the coupler

Question 7

Scaffold boards must comply with:

TheoryPractice · Accepted Answer

AS 1577 (scaffold planks) or be steel/aluminium decking rated for the required load

Question 8

The maximum overhang of a scaffold board beyond its support (transom) is:

TheoryPractice · Accepted Answer

4 times the board thickness (typically up to about 150 mm for a 38 mm board)

Question 9

What is a 'spigot' used for in system scaffolding?

TheoryPractice · Accepted Answer

Joining two standard tubes end-to-end (top-to-bottom connection)

Question 10

Aluminium scaffold components must not be used:

TheoryPractice · Accepted Answer

In environments where they contact substances that attack aluminium (e.g. strong alkalis in wet cement)
