Which ladder rungs are prohibited for standing while working on a ladder?

Standing on the top two rungs of a ladder is prohibited due to safety regulations and guidelines designed to minimize the risk of falls. When a person stands on these upper rungs, they are at a greater height and have a significantly reduced center of gravity. This increases the likelihood of losing balance or tipping the ladder, especially if they are reaching out or leaning too far to either side.

By restricting use to the lower rungs, workers have a more stable base and can maintain better balance while performing tasks. Additionally, safety protocols often highlight that maintaining three points of contact while climbing or working on a ladder is crucial for preventing accidents. Thus, avoiding the use of the top two rungs supports the principle of safe ladder use, contributing to overall worker safety while operating at heights.
