What body position should a signal person maintain to ensure visibility to the operator?

The correct answer emphasizes the importance of staying within the operator's line of sight while also maintaining a safe distance. This practice ensures that the signal person can effectively communicate with the crane operator through visual signals, which is crucial for safe operations. By being visible to the operator, the signal person can provide real-time instructions and alerts about the load's movement, potential hazards, and the surrounding environment.

Maintaining a safe distance is also vital to protect the signal person from any unpredictable movements or accidents that may occur during operation. This balance of visibility and safety is essential in crane operations, where clear communication can prevent accidents and ensure that tasks are completed safely and efficiently.

In contrast, standing behind the crane could obstruct the operator's view and create a dangerous situation. Being as far away as possible detracts from effective communication, and positioning oneself at the operator's side may not offer the same visual clarity for signaling as staying in a designated line of sight.
