PASMA Tower Assembly Methods 5

Question 1

What documentation should accompany a tower scaffold system on site?

Accepted Answer

The manufacturer's instruction manual and user guide

Answer

The manufacturer's instruction manual must be available on site. It contains essential information on assembly sequences, maximum heights, load capacities, and safe use. This is required under PUWER 1998.

Question 2

What is the minimum guard rail height required on a tower scaffold platform?

Accepted Answer

950mm above the platform

Answer

Guard rails must be at least 950mm above the platform surface. An intermediate guard rail (or mid-rail) should also be fitted so the gap between any guard rail, toeboard, or platform does not exceed 470mm.

Question 3

What is the maximum gap permitted between a toeboard and the next guard rail above it?

Accepted Answer

470mm

Answer

The maximum unprotected gap must not exceed 470mm. This prevents a person from falling through or materials from passing between the toeboard top and the bottom of the intermediate guard rail.

Question 4

Who is permitted to assemble, alter, or dismantle a PASMA mobile tower scaffold?

Accepted Answer

Only persons who have received appropriate training, such as PASMA training

Answer

Under the Work at Height Regulations 2005, Schedule 6, towers must only be assembled, altered, or dismantled by persons who have received appropriate training. PASMA training is the industry standard recognised qualification.

Question 5

What is a 'cantilever' platform on a tower scaffold used for?

Accepted Answer

To extend the working platform beyond the base footprint of the tower

Answer

A cantilever platform extends the working area beyond the tower's base. It must only be used if specified in the manufacturer's instructions, as it affects the tower's stability and loading characteristics.
