How many workers can responsibly give signals to the crane operator?

In crane operations, effective communication is essential for safety and efficiency. Having only one person giving signals to the crane operator helps to eliminate confusion and ensures that the operator receives clear and consistent instructions.

When multiple individuals attempt to signal the crane operator, it can lead to mixed signals or competing instructions, which can create dangerous situations. The designated signal person is trained to understand the operator's perspective and the specific movements required, allowing for safe maneuvering of loads.

Thus, designating a single signals person establishes a streamlined communication process, minimizes potential errors, and enhances the overall safety of the lifting operation. This is why selecting one worker to be responsible for signaling is the preferred practice.
