Whenever there is a concern as to safety, the operator must have the authority to stop and refuse to handle loads until a qualified person has determined that safety has been assured. AUTHORITY TO STOP 1926.1419 - Signals--general requirements.
A signal person must be provided in each of the following situations:
The point of operation, meaning the load travel or the area near or at load placement, is not in full view of the operator.
When the equipment is traveling, the view in the direction of travel is obstructed.
Due to site specific safety concerns, either the operator or the person handling the load determines that it is necessary.
Types of signals. Signals to operators must be by hand, voice, audible, or new signals.
