Correct Answer

Why This Is the Correct Answer
Crane operations need clear, qualified signaling when the operator's view or communication is limited.
Why the Other Options Are Wrong
Option A: follow the loudest spotter
follow the loudest spotter may relate to another site control, but it does not remove or guard the crane signal control exposure being tested.
Option B: average the conflicting signals
average the conflicting signals may relate to another site control, but it does not remove or guard the crane signal control exposure being tested.
Option C: speed up to clear confusion
speed up to clear confusion may relate to another site control, but it does not remove or guard the crane signal control exposure being tested.
