According to B30.5, who must test all signal persons prior to qualifying?

The statement that a designated person must test all signal persons prior to qualifying is consistent with B30.5 standards, which emphasize the importance of proper training and assessment in crane operations. The designated person is typically responsible for ensuring that all safety protocols and procedures are adhered to within the work environment, which includes evaluating the competency of signal persons.

This individual has the authority and responsibility to ensure that signal persons can effectively communicate and manage signals for crane operations, thereby enhancing workplace safety. This requirement reinforces the idea that safety should be managed by trained personnel who understand the specific demands and characteristics of the job site and the equipment used.

In contrast, other roles, while important, do not have the direct responsibility for testing signal persons. Crane operators, site supervisors, and equipment manufacturers focus on different aspects of crane operation and safety, which is why the designated person is the correct choice for this responsibility.
