Which term refers to the role of personnel outside the apparatus when it is backing up?

The term "spotters" refers to the personnel assigned to monitor and assist when an apparatus is backing up. When emergency vehicles, like fire apparatus, are reversing, visibility can be limited for the driver. Spotters are positioned outside the vehicle, typically at the rear, to guide the driver safely and ensure that the path is clear of obstacles or personnel. Their role is critical in preventing accidents and ensuring a safe backing maneuver.

This term specifically emphasizes the active role these personnel play in spotting potential hazards and directing the driver, distinguishing their function from other roles such as safety observers, ground support, or traffic control, which may involve different responsibilities in fire scene management or general safety oversight.
