Where must a hand signal chart be posted according to B30.5?

A hand signal chart must be posted conspicuously to ensure that it is easily visible and accessible to all personnel involved in crane operations. This visibility is crucial for effective communication among ground workers and the crane operator. When the chart is conspicuously placed, it reduces the likelihood of misunderstandings or errors during crane operations, thereby enhancing safety.

Placing it near the crane might not guarantee that all personnel can see it at the required moment, especially if they are positioned farther away. Similarly, while putting it in the operator's cabin ensures the operator has it handy, it doesn't help ground crew members who need to signal the operator. Posting it in the maintenance log would be impractical, as that location is not meant for immediate reference during operations.
