Which most commonly used command method must stacker operation and command personnel be familiar with?

The most commonly used command method that stacker operation and command personnel should be familiar with is gesture. Gesture commands are particularly effective in environments where noise may impede verbal communication, making visual signals crucial for safety and operational efficiency.

In a forklift operation context, gesture commands enable personnel to communicate quickly and effectively over distances, particularly in busy or crowded environments. This method ensures that both the operator and ground personnel understand each other clearly, minimizing the risk of accidents.

Other command methods may have their uses, but gesture commands stand out due to their immediacy and clarity in situations where verbal communication may be impractical or unsafe.
