Who is allowed to signal the crane?

The correct answer highlights that the flagger and the signal person are specifically designated individuals responsible for ensuring safe crane operations. The flagger typically manages traffic and ensures that the path is clear for the crane and its load, while the signal person communicates directly with the crane operator, directing the movements of the crane and ensuring that lifting operations are conducted safely.

It's essential to have these defined roles to maintain safety standards on job sites, as having multiple individuals signal the crane can lead to confusion and misunderstandings. Having designated personnel ensures clear communication and proper coordination, which is crucial in preventing accidents during lifting operations. By relying on the flagger and the signal person, the operation can be managed more effectively, reducing the risk associated with crane lifts.

Other options suggest allowing either multiple workers, just two workers, or a combination of a lift director and crane signal person. These arrangements can lead to ambiguity in responsibility and signal communication, which can compromise safety during crane operations.
