During the hoisting of a personnel platform, who must the signalman maintain continuous communication with?

The correct answer emphasizes the critical importance of continuous communication between the signalman, the operator, and the platform occupants during a hoisting operation. Maintaining this line of communication is essential for ensuring safety and coordination throughout the entire lifting process.

The signalman plays a vital role in guiding the operator to move the personnel platform safely and effectively. Continuous communication with the operator allows the signalman to provide real-time updates about the platform’s position and any potential hazards. Simultaneously, maintaining contact with the platform occupants is crucial as they can inform the signalman about their movements and any immediate concerns they may experience while being lifted. This two-way communication enables timely responses to changing conditions, enhancing safety for everyone involved.

In contrast, the other options emphasize communication with either only the operator, only the platform occupants, or only the ground crew, which would not ensure the comprehensive safety and situational awareness needed during personnel hoisting operations. Effective collaboration among all parties is essential to prevent accidents and ensure that the operation is conducted smoothly and safely. Therefore, maintaining continuous communication with the operator and platform occupants is the most sensible and safe approach.
