Explanation:
Detailed explanation-1: -Maintain three-point contact by keeping two hands and one foot, or two feet and one hand on a ladder always.
Detailed explanation-2: -The base of the ladder should be placed so that it is one foot away from the building for every four feet of hight to where the ladder rests against the building. This is known as the 4 to 1 rule.
Detailed explanation-3: -When climbing up or down a ladder, a worker must always follow the “three points of contact” rule (two hands and a foot, or two feet and a hand). The three contact points must be applied if you’re getting on and off heavy equipment, ladders, or other work platform surfaces.
