Which scenario is prevented by effective use of the YFB?

Effective use of the Yard Function Board (YFB) is crucial for maintaining operational efficiency in yard management. One of its primary purposes is to prevent situations that can lead to gridlock in the yard. When yard operations are well-coordinated using the YFB, it helps to streamline processes, ensuring that vehicles, equipment, and personnel are properly scheduled and positioned. This organized layout reduces congestion and optimizes the flow of operations.

In contrast, delayed maintenance of equipment often results from ineffective scheduling rather than the direct role of the YFB in daily operations. Insufficient safety training is a separate concern that relates to personnel preparedness, and inaccurate inventory management, while important, pertains more to tracking and organizing stock rather than the physical movement within the yard. Thus, the YFB specifically addresses coordination and efficiency, leading to a smoother operation and effectively preventing gridlock.
