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

The correct answer is that a hand signal chart must be posted conspicuously according to ASME B30.5. This requirement ensures that all personnel involved in lifting operations, including operators and ground crew members, can easily see and reference the signals necessary for safe communication during operations.

Posting the chart in a conspicuous manner reinforces the importance of clear communication between signal persons and equipment operators, minimizing the risk of misunderstandings that could lead to accidents or injuries. Having the chart visible ensures that everyone on the job site has access to this crucial information at all times, fostering a safer work environment.

Other options, such as making the chart visible only to operators or available online, would not provide the same level of accessibility and may lead to communication breakdowns, especially in high-noise environments or when operators are under stress. Storing the chart in a training manual would also limit its immediate availability during actual lifting operations, which is counterproductive to maintaining safety on the job site.
