Theperson in the ladder will be unable to maintain a three point of contact resulting to a fall and injury. 9. Apply the 1:4 rule. When using leaning ladders like an extension ladder, the position of the ladder should be angled at a ratio of 1:4. The base of the ladder being 1 meter away from the structure for every meter height of 4. 10.
makesure the ladder angle is at 75° – you should use the 1 in 4 rule (ie 1 unit out for every 4 units up) – see Figure 1; always grip the ladder and face the ladder rungs while climbing or descending – don’t slide down the stiles; don’t try to move or extend ladders while standing on the rungs; don’t work off the top three rungs

For every 4 feet in height, the base of the ladder should be positioned 1 foot away from the wall. This ratio helps maintain a stable climbing angle of approximately 75 degrees. 2.
