Question 1

What inspection regime applies to a scaffold that is in use for more than seven days?

Accepted Answer

Inspection at least every seven days

Answer

Under the Work at Height Regulations 2005, a scaffold in use for more than seven days must be inspected at intervals not exceeding seven days. This ensures that deterioration from weather or use is identified promptly.

Question 2

Which body produces the NASC TG20 guidance for tube-and-fitting scaffolding?

Accepted Answer

National Access and Scaffolding Confederation (NASC)

Answer

The National Access and Scaffolding Confederation (NASC) produces TG20, which is the industry guidance for the design and erection of tube-and-fitting scaffolding in the UK. It provides a good practice guide for scaffolding.

Question 3

What is the minimum toe board height on a scaffold platform?

Accepted Answer

150mm

Answer

Toe boards on scaffold platforms must be at least 150mm high. They prevent tools, materials and debris from rolling or being kicked off the edge of the platform onto workers or members of the public below.

Question 4

What is a 'safety net' used for in working at height?

Accepted Answer

To catch workers or materials that fall from a height

Answer

Safety nets are collective protective measures that are installed below working areas to catch workers and materials if they fall. They must be installed as close as practicable to the working level to minimise free fall distance.

Question 5

What is the primary hazard of working on fragile roofs?

Accepted Answer

The roof surface may give way under the weight of a worker, causing a fall

Answer

Fragile roofs (such as corrugated asbestos cement, fibreglass or old glass) may not support the weight of a worker. If the surface gives way, the worker falls through to the ground below, which can result in fatal injuries.
