What is a spotter and when is one required?

• A. A person who operates the crane.
• B. A person who issues permits.
• C. A person observer from a distance.
• D. A person guiding the operator around blind spots; required for lifts or when visibility is restricted.

Answer: (D)

A spotter is the person who guides the crane operator by watching areas the operator cannot see and directing moves to avoid hazards. They help ensure there’s a clear path, preventing contact with people, vehicles, or structures in the load’s swing area. They watch for obstacles and workers, and they communicate the operator’s instructions through standard hand signals or radios, keeping the operator’s visibility and control coordinated.

This role is required during lifts or whenever visibility is restricted, such as when the load blocks the operator’s view, the area is crowded, or conditions limit sight lines. The spotter is not the crane operator, nor is this the person who issues permits, nor merely an observer from a distance. Having a spotter in these situations enhances safety by providing real-time guidance around blind spots and restricted visibility.
