A signal person must be used when the equipment operator's view is obstructed or the point of operation is not fully visible to the operator. This usually applies to crane operations and heavy machinery movements where safety is a concern. The signal person acts as the eyes and ears of the operator, communicating hand signals, voice commands, or radio signals to guide safe equipment movement, avoid hazards, and ensure no personnel are in danger zones. A signal person is also required when the operator or load handler deems it necessary for safety reasons. This is typically mandated by OSHA regulations for construction and heavy equipment operations.
Key Situations When a Signal Person Must Be Used
- When the operator’s view of the load or operation site is blocked.
- When the path of operation is obstructed or not in full view.
- When heavy loads are being moved in congested or hazardous areas.
- When safety regulations, such as OSHA, require a signal person.
- Whenever the operator or site safety team determines that additional guidance is needed for safe operation.
Purpose and Responsibilities of a Signal Person
- Communicate clear and standardized signals to the operator.
- Ensure the path is clear of obstacles and people.
- Monitor load stability and environment.
- Be prepared to give emergency stop commands when necessary.
- Coordinate with the operator and other site personnel to maintain safety.
In summary, a signal person must be used whenever the operator’s visibility is compromised or when safety conditions require guided communication to prevent accidents during equipment operation.
