According to ASME B30.23, who is designated to communicate with the operator in a suspended personnel platform without boom motion controls?

In a suspended personnel platform without boom motion controls, the designated individual to communicate with the operator is a signal person. This designation is crucial for ensuring safety and effective communication during operations involving personnel being lifted or moved. The signal person's primary role is to relay necessary instructions and information to the operator regarding the movement and positioning of the platform.

The signal person is trained to understand the specific signals used to communicate with the operator effectively, which is essential for preventing accidents and ensuring that the personnel on the platform are moved safely. Moreover, they have the responsibility to assess the environment and the conditions affecting the operation, ensuring that all safety protocols are followed.

Options such as management, a safety officer, or a ground worker may play important roles in the overall safety management of lifting operations, but their primary responsibilities do not specifically include direct communication with the operator during operations of a suspended personnel platform. Their involvement is typically broader and may encompass oversight and safety compliance rather than the specialized signal communication required in the immediate operation.
