Question 1

What is the maximum height a ladder should project above the landing point?

Accepted Answer

At least 1 metre above the landing point

Answer

Ladders should project at least 1 metre above the landing point to provide a handhold when stepping on and off the ladder. This helps prevent overbalancing when transitioning from the ladder to the working platform.

Question 2

At what angle should a leaning ladder be positioned?

Accepted Answer

75 degrees (1 out for every 4 up)

Answer

A leaning ladder should be positioned at 75 degrees, which corresponds to a ratio of 1 unit out for every 4 units up. This angle provides the correct balance between stability and ease of climbing.

Question 3

Under the Work at Height Regulations, when are ladders an appropriate means of access?

Accepted Answer

When the risk assessment shows that using more suitable work equipment is not justified because of the short duration of use or existing site features

Answer

Ladders are appropriate when the risk assessment shows that more suitable equipment is not justified — typically for short-duration work where the risk is low. Ladders are access equipment, not a working platform for prolonged tasks.

Question 4

What does PASMA stand for in the context of mobile tower scaffolds?

Accepted Answer

Answer
