Explanation:
Detailed explanation-1: -To use ladders safely, always maintain three points of contact. That means two hands and one foot or two feet and one hand on the ladder at all times. Moving quickly often results in only 2-point contact. You often have to make a conscious effort to maintain 3-point contact.
Detailed explanation-2: -When using a straight ladder, the top of the ladder must exceed the height of the structure it’s leaned on by three feet and it must be leaned at a 75-degree angle-i.e. 1:4 or 1 foot out from the wall for every four feet of ladder height.
