In lifting operations, what is the role of a dedicated signal person, and when is it required?

• A. Provide medical aid
• B. Inspect the load
• C. Operate the crane remotely
• D. Direct crane movements when visibility or line-of-sight between operator and load is limited; required by standards for lifts with restricted visibility or hazards

Answer: (D)

Directing crane movements when the operator cannot clearly see the load or the path of travel is the core duty of a dedicated signal person. This role acts as the clear communication link between the operator and the load, using standardized hand signals or radios to guide lifting, positioning, and movement. The signal person keeps the lift coordinated, helps prevent swings or collisions, and can stop the operation if signals are unclear or danger arises. They must be trained, positioned to see both the load and the crane, and remain the sole communicator for the lift. Standards require this role for lifts with restricted visibility or other hazards, ensuring safe and predictable crane operation. The other tasks listed—providing medical aid, inspecting the load, or operating the crane remotely—are not the signal person’s responsibilities.
