When is it appropriate to use verbal signals in conjunction with hand signals?

Using verbal signals in conjunction with hand signals is particularly appropriate when visibility is poor or when distant communication is necessary. In situations where visibility is compromised—whether due to lack of light, obstructions, or adverse weather conditions—hand signals can become difficult to see and interpret accurately. Verbal signals serve as a crucial complement during these times, providing clear, audible instructions that can be heard even if visual cues are not effectively communicated.

Additionally, when operators are far apart, such as in large outdoor setups or noisy environments where hand signals may not be easily seen, verbal communication becomes essential. This ensures that all personnel involved in the operation remain coordinated and safe, reducing the risk of miscommunication and accidents. Prioritizing clear communication parameters in challenging conditions is vital for maintaining safety in crane operations.
