When a signalman is on the ground during the hoisting of a personnel platform, between whom must they maintain communication?

The correct choice emphasizes the critical need for communication between the operator and the occupants of the personnel platform during hoisting operations. This interaction ensures that the operator is fully aware of the conditions and status of the individuals aboard the platform, which is essential for maintaining safety and effective operations. The platform occupants may need to communicate their readiness to the operator or alert them to any potential hazards while they are being lifted or lowered.

This communication is vital not only to facilitate the smooth operation of the lift but also to respond promptly to any emergencies or changes in the environment that could affect the safety of the personnel. By ensuring direct communication between the operator and those on the platform, risks can be minimized, and effective responses to any issues can be implemented swiftly.
