What is a key reason to avoid standing on the top of a step ladder?

Standing on the top of a step ladder is discouraged primarily because it causes instability. When a person stands at the highest point of a ladder, they can significantly compromise their balance and center of gravity. This height can make it difficult to maintain a secure stance, leading to a higher risk of falling, which is one of the main hazards associated with ladder use.

For safety purposes, ladder manufacturers and safety guidelines typically advise users to stay at least two rungs down from the top, ensuring that there is adequate support and minimizing the risk of tipping over. This practice helps maintain stability while performing tasks at height, allowing the worker to work more safely and effectively.
