What does the three-point rule in ladder safety require?

The three-point rule in ladder safety specifically requires that three points of contact be maintained while climbing or descending a ladder. This rule is crucial for ensuring stability and reducing the risk of falls. By having three points of contact—either two hands and one foot or two feet and one hand— a worker can maintain balance and secure themselves better while on the ladder, which enhances safety during ladder use.

This method is vital because the ladder can shift or become unstable; having three points of contact ensures that the worker can quickly stabilize themselves and prevents sudden slips that could lead to injuries. It emphasizes the importance of safety measures in construction and maintenance tasks, where the potential for accidents is significant.

Other options presented do not adequately capture the comprehensive idea of maintaining three points of contact, which is essential for maximizing safety during ladder operations.
