What is the correct angle ratio for leaning a ladder against a wall?

The correct angle for a leaning ladder is a 1:4 ratio — for every 4 units of height, the base should be 1 unit out from the wall. This gives an angle of approximately 75 degrees, providing optimal stability and minimising the risk of the ladder slipping.

1:2 ratio (1 out for every 2 up)

1:4 ratio (1 out for every 4 up)

1:3 ratio (1 out for every 3 up)

1:5 ratio (1 out for every 5 up)

What does the '3-point contact' rule mean when using a ladder?

The 3-point contact rule means the climber must always have at least two hands and one foot, or two feet and one hand, in contact with the ladder. This ensures stability and reduces the chance of losing balance and falling.

The ladder must be supported at three separate points along its length

Three workers must be present whenever a ladder is in use

The user must maintain two hands and one foot, or two feet and one hand, on the ladder at all times

The ladder must be tied off at the top, middle, and base before climbing

According to HSE guidance, ladders should generally only be used for work at height tasks lasting no more than how long?

HSE guidance states that ladders should only be used for short-duration tasks, typically no more than 30 minutes. If the task will take longer, a more suitable and safer means of access such as a scaffold or MEWP should be used.

Sample questions

01What is the correct angle ratio for leaning a ladder against a wall?
- A.1:2 ratio (1 out for every 2 up)
- B.1:3 ratio (1 out for every 3 up)
- C.1:4 ratio (1 out for every 4 up)
- D.1:5 ratio (1 out for every 5 up)
Why: The correct angle for a leaning ladder is a 1:4 ratio — for every 4 units of height, the base should be 1 unit out from the wall. This gives an angle of approximately 75 degrees, providing optimal stability and minimising the risk of the ladder slipping.
02What does the '3-point contact' rule mean when using a ladder?

- B.The ladder must be tied off at the top, middle, and base before climbing
- C.Three workers must be present whenever a ladder is in use
- D.The user must maintain two hands and one foot, or two feet and one hand, on the ladder at all times
Why: The 3-point contact rule means the climber must always have at least two hands and one foot, or two feet and one hand, in contact with the ladder. This ensures stability and reduces the chance of losing balance and falling.
03According to HSE guidance, ladders should generally only be used for work at height tasks lasting no more than how long?
- A.1 hour
- B.2 hours
- C.10 minutes
- D.30 minutes
Why: HSE guidance states that ladders should only be used for short-duration tasks, typically no more than 30 minutes. If the task will take longer, a more suitable and safer means of access such as a scaffold or MEWP should be used.
