What distinguishes a rigger from a signal person?

The distinction between a rigger and a signal person is primarily based on their specific roles and responsibilities in the rigging process. A rigger is trained to handle the rigging equipment, ensuring that it is appropriately set up and secure for lifting operations. They are also responsible for selecting and checking the rigging gear used, ensuring that it complies with safety standards and is suitable for the load being lifted.

Simultaneously, a signal person plays a crucial role in communication; they direct the movement of the load, relaying commands to the crane operator to ensure the load is moved safely and accurately. This division of responsibilities is vital for maintaining safety and coordination on-site during lifting operations.

Option D accurately captures this division: it specifies that the rigger handles the rigging equipment while the signal person is tasked with directing the load. This delineation of duties is essential for ensuring that both roles complement each other to prevent accidents and ensure efficient operation.
