How many points of contact must be maintained on a ladder at all times?

Maintaining three points of contact on a ladder at all times is crucial for ensuring safety and stability. This involves two hands and one foot, or two feet and one hand, remaining in contact with the ladder. By having three points of contact, the user's center of gravity is lowered, and their balance is significantly improved, reducing the risk of slipping or falling. This practice is a fundamental safety guideline in ladder use, as it maximizes stability and support.

In contrast, having only two points of contact may create a situation where the user is less stable and more prone to losing balance. Relying on just one point of contact severely compromises safety, as it makes the user more likely to fall. Thus, the importance of having three points of contact cannot be overstated when it comes to safe ladder usage.
