What is an essential practice for two workers using a ladder simultaneously?

The essential practice for two workers using a ladder simultaneously is to focus on looking down when descending. This practice is crucial because it helps ensure that each worker maintains awareness of their surroundings and the ladder's position as they navigate downwards. Looking down allows individuals to properly judge their steps, reducing the risk of missteps or accidents that could occur from distractions or miscalculations.

When descending a ladder, proper posture and focus on where to place feet can help in maintaining balance and preventing falls, which is a major safety concern in ladder usage. Ensuring good visibility of the footholds and the surrounding area enhances stability and minimizes the risk of injuries.

Other options might involve practices that are not as critical to safety during simultaneous ladder use. For instance, while positioning themselves on opposite sides may help with balance, it can also create confusion and increase the risk of collision. Holding hands for support is generally impractical and dangerous on a ladder, and ensuring that the ladder is extended is more relevant to preparation than to the simultaneous use by two workers.
