How much time must a train approach warning allow for workers to move to safety?

The correct response indicates that a train approach warning must allow for workers to have at least 15 seconds to move to safety. This timeframe is critical to ensure that all workers have sufficient opportunity to evacuate the work area in a safe manner before a train arrives.

The 15-second warning period is grounded in practices that prioritize safety on the job, taking into account different variables such as the speed of the train, the proximity of the workers to the tracks, and the time it takes for a worker to react and reach a safe location. This ample time window allows for effective communication, reduces panic, and provides a buffer for unexpected situations that could delay a worker's evacuation.

In addition, standards for worker safety have been developed through thorough assessments of typical train speeds and stopping distances, helping to establish this critical rule. Adhering to this time requirement helps to significantly minimize the risk of accidents and injuries on or near the tracks.
