Where is the hand signal chart supposed to be posted when lifting a personnel platform according to ASME B30.23?

The correct choice indicates that the hand signal chart should be posted in the personnel platform. This placement is essential because it ensures that individuals working on the personnel platform have easy access to the hand signals being used during operation. Having the chart within sight allows them to quickly reference the signals, promoting effective communication between the signal person and the crane operator. This is critical during operations where clear and immediate understanding of signals can enhance safety and efficiency.

In contrast, options suggesting placement elsewhere, such as the base of the crane, within the operator's view, or near the ground control panel, do not provide the same level of accessibility for personnel actually on the platform. While those areas may be conducive for other communication tools, the personnel working on the platform should directly have the signal chart available to them to minimize any potential delays or misunderstandings. Thus, posting the hand signal chart within the personnel platform aligns with best practices for safety and operational efficiency.
