When transferring from a ladder to an elevated position, how many inches should the ladder side rails extend above the landing?

The correct height for the extension of ladder side rails above the landing is 36 inches. This measurement is in accordance with safety standards, which specify that when transferring from a ladder to an elevated position, the side rails must extend sufficiently to provide stable handholds and prevent accidents during the transition.

By having the ladder extend at this height, workers can effectively maintain three points of contact while transferring—two feet and one hand or two hands and one foot, ensuring stability and safety. The 36-inch extension allows for a secure grip and minimizes the risk of slipping or falling as the individual steps off the ladder to the landing.

In practice, options that exceed this height may provide unnecessary extension which could pose other safety risks, such as being cumbersome or difficult to maneuver. The 36-inch standard strikes a balance between safety and practicality in ladder use.
