During a lift, which action is least likely to be performed by a spotter?

• A. Provide ground-level visibility and communicate hazards to the operator and rigging team.
• B. Adjust the crane's load chart without the operator.
• C. Maintain safe clearance around the lift.
• D. Signal the operator with hand or radio when hazards exist.

Answer: (B)

Understanding the spotter’s role during a lift is about safety communication and situational awareness. A spotter provides ground-level visibility to ensure the operator can see hazards and obstacles, helps maintain safe clearance around the lifting area, and signals the operator (by hand or radio) whenever hazards or obstructions exist. The task that is least likely to be done by a spotter is adjusting the crane’s load chart without the operator. The load chart is the crane’s rated capacity for specific configurations and radii, and it is used by the operator (often with guidance from a supervisor) to determine if a lift is within safe limits. Changes to or interpretation of the chart should not be performed by the spotter; if a lift risks exceeding capacity, the lift must be stopped and properly reassessed by the qualified personnel.
