What is the maximum distance for using manual hand signals between the operator and signal person?

The maximum distance for using manual hand signals between the operator and the signal person is established to ensure effective communication during operations. At a distance of 100 feet (30.4 meters), the signals can still be seen clearly by the operator, allowing for timely responses and minimizing the risk of accidents. Effective communication is crucial in construction and heavy equipment operations, where misunderstandings can lead to dangerous situations.

Setting the maximum distance at 100 feet balances practicality and safety, ensuring that both the signal person and the operator can easily see and interpret the signals being conveyed. Distances greater than this can significantly hinder the ability to use hand signals effectively, which might lead to miscommunication and increase the risk of incidents on the worksite.
