What does one light or bell signal represent?

1. Stop

2. Raise

3. Lower slowly

4. Lower

The correct answer is: Stop

One light or bell signal is conventionally used to indicate a stop command. In crane and hoisting operations, clear communication is crucial for safety, and signals are established to avoid misunderstandings that could lead to accidents. The stop signal is typically a solid light or a distinct bell sound that operators recognize immediately as a command to cease all movement. This signal is essential because it helps to ensure that all personnel involved in the hoisting activities are aware that the load or equipment must no longer be moved. Understanding this signal is vital for maintaining a safe working environment, especially in busy or noisy job sites where verbal communication may be compromised.
