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

• A. The bottom rung
• B. The top two rungs
• C. The middle rung
• D. All rungs if working alone

Answer: (B)

The correct answer is that standing on the top two rungs of a ladder is prohibited while working. This safety guideline is established because standing on these upper rungs can significantly increase the risk of losing balance and falling, as it raises a person’s center of gravity beyond a stable point. The top rungs lack spread and support, and workers do not have a secure handhold for stability. When working from a ladder, it’s essential to maintain safe practices to avoid potential falls and injuries. Therefore, adhering to safety regulations about the use of ladders, specifically avoiding the top two rungs, is crucial for ensuring a safe working environment. While other options mention various rungs as prohibited, the emphasis on the top two rungs specifically recognizes the heightened danger associated with being elevated without proper support and safety measures.
