Answer

Brief Explanations:

When using hand - signals for communication in work or vehicle - related scenarios, maintaining eye contact with the operator is crucial for clear and effective communication. This ensures that the operator sees the signals and understands their meaning. Ensuring a backup alarm can be heard is related to auditory safety, standing on something 2' high is not a general requirement for hand - signals, and while wearing reflective gloves can increase visibility, it is not always necessary for hand - signal communication.

Answer:

C. maintain eye contact with the operator
