According to ASME B30.23, where should a hand signal chart be posted while lifting a personnel platform?

A hand signal chart should be posted in the crane, as it ensures that the operator can easily reference the signals while performing lifts. Having the chart in the crane allows for quick visual access to the standardized signals, which is essential for maintaining clear communication between the signal person and the crane operator during operations, especially when lifting personnel platforms. This placement minimizes the potential for miscommunication and enhances safety, as both parties can refer to the same source of information in real-time.

While other locations might seem convenient, they do not provide the same level of accessibility during crucial lifting operations. For example, placing it in the operator's cabin or at the ground level control station may create delays in communication when signals need to be confirmed or clarified. Keeping the chart within the crane ensures that it is always in sight and readily available, promoting safer lifting practices.
