Which of the following equipment is commonly associated with a signal person?

A signal person is predominantly associated with cranes and hoists because these types of equipment often involve lifting heavy loads where clear communication is crucial. The role of a signal person is to direct the operation of cranes, ensuring safety and precision during the lifting and moving of materials.

Cranes and hoists require a signal person to utilize hand signals or radio communication to relay instructions to the operator while maintaining visibility of the load and its surroundings. This responsibility is vital in preventing accidents and ensuring that loads are lifted and positioned correctly, especially in congested or complicated environments.

While excavators, forklifts, and scissor lifts may also require guidance during operations, the specific need for a signal person is most critical in situations involving cranes and hoists due to the inherent risks associated with lifting operations and the need for precise coordination.
