What is the recommended number of points of contact when climbing a ladder?

• A. Two points of contact
• B. Three points of contact
• C. Four points of contact
• D. Five points of contact

Answer: (B)

Maintaining three points of contact provides a stable base as you climb, keeping your center of gravity close to the ladder and reducing the chance of a slip or fall. With three points in contact, you can move one limb while the other two remain secure, then bring up the third point. This could be two hands and one foot on the ladder, or two feet and one hand, at all times while climbing or descending.

Two points of contact is not enough to reliably support you if you shift, reach, or encounter a slip. Four points of contact can be more stable, but it isn’t the standard minimum and can limit movement and reach. Five points would be impractical for climbing. The key idea is to keep at least three points touching the ladder to maintain balance and control as you move.
