What procedure should be followed regarding personnel before moving car(s) on a shop track?

The correct procedure regarding personnel before moving car(s) on a shop track is that personnel must be removed from the track area. This practice is crucial for maintaining safety during the movement of equipment. Removing personnel from the track reduces the risk of injury in the event of an unexpected situation, such as equipment malfunction or operator error. It ensures that there is a clear and safe working environment for both the workers and the equipment being moved.

While the other choices might seem reasonable in some contexts, they could potentially compromise safety. For instance, having personnel on the equipment or allowing them to remain in the area, regardless of whether tools are secured, increases the risk of accidents. The requirement for personnel to signal movements, while beneficial in certain operations, is not a substitute for ensuring that no personnel are in the vicinity of moving cars, which is a critical safety measure.
