Who should be designated to communicate with the operator of a personnel platform, according to ASME B30.23?

The designation of a signalman to communicate with the operator of a personnel platform is based on the critical role that this individual plays in ensuring safe and effective operations. The signalman is specifically trained to understand hand signals and other communication methods that are essential for coordinating movements of the crane and personnel platform. This training enables them to accurately convey information about load positioning and any changes that may arise during the lift, which is vital for maintaining safety and preventing accidents.

Additionally, the signalman is positioned to have a clear line of sight to both the operator and the personnel platform. This visibility allows for better communication and ensures that any hazards can be promptly addressed. Other individuals such as ground observers, management representatives, or safety inspectors may have their roles, but they do not possess the specialized training and focus required to interact directly and effectively with the crane operator regarding the dynamic nature of personnel lifts. Their responsibilities often lie in oversight or support roles rather than direct communication during operations.
