What is an important safety measure when ascending a ladder?

Maintaining three points of contact at all times is crucial for ladder safety because it provides maximum stability and balance while ascending or descending. This practice involves having two hands and one foot, or two feet and one hand, in contact with the ladder at any given time. This significantly reduces the risk of falling, as it enhances a climber's ability to maintain grip and support.

When all three contact points are used, the body’s center of gravity remains controlled, and it allows for the necessary movement without the risk of tipping over. This is especially important in maintaining balance and ensuring a secure ascent or descent on the ladder, which is a time when falls are more likely to happen.

Other choices do not prioritize safety effectively; for instance, carrying items or looking down can distract from maintaining proper balance and awareness of your surroundings, while climbing quickly increases the risk of slips or loss of control.
