Which option is NOT a standard signaling method in crane operations?

• A. Hand signals
• B. Two-way radio communication
• C. Written notes exchanged during the lift
• D. Standardized signals for lifting, lowering, hoisting, traveling

Answer: (C)

In crane signaling, communication methods must be immediate, clear, and consistently understood by everyone involved. Standardized hand signals and two-way radio communication are built into training and procedures so the signaler and operator can respond quickly and correctly, even in loud work environments. These signals cover lifting, lowering, hoisting, and traveling, and are defined so that interpretation is the same no matter who is signaling. Written notes exchanged during the lift do not fit as a standard signaling method because they require reading and visible access, which can introduce delays, misreading, or being out of sight in dynamic lift situations. This makes them unreliable for real-time guidance. While notes might be useful for documentation or planning outside the lift, they aren’t a recognized standard way to convey lift commands.
