National Commission for the Certification of Crane Operators (NCCCO) Mobile Crane Practice Exam

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

1. In the operator's manual

2. At the crane maintenance facility

3. On the job site

4. In the safety briefings

The correct answer is: On the job site

The hand signal chart must be posted at the job site to ensure that all personnel involved in crane operations can easily access and reference it during lifting operations. This visibility promotes effective communication among the crane operator, signal person, and other workers, which is critical in preventing accidents and ensuring safety on site. Having the hand signal chart at the job site allows for immediate reference and reduces the potential for misunderstandings that could arise from unclear signals. It serves as a constant reminder of the proper signals to use, which is essential for maintaining safe practices in real-time operations. While including the chart in the operator's manual is useful for guidance and training, it may not provide the immediate access required on site. Posting it at the crane maintenance facility or discussing it in safety briefings also does not offer the same level of constant visibility needed for daily operations at the job site.
