What is the minimum clearance distance from a track where workers should not be located?

The minimum clearance distance from a track where workers should not be located is 15 feet from the nearest rail unless they are protected by appropriate safety measures. This distance is established to ensure the safety of personnel working near railroad tracks, accounting for the potential hazards of passing trains and equipment.

Maintaining a clearance of 15 feet allows workers to stay out of the immediate danger zone, where they could be at risk of coming into contact with moving trains or equipment. Additionally, the mention of "unless protected" underscores that in certain situations, specific protective measures (such as the use of non-conductive barriers or proper safety equipment) can allow for workers to be closer to the tracks if they are adequately safeguarded.

In environments with railroad operations, understanding and adhering to these safety distances is crucial to prevent accidents and ensure the well-being of roadway workers.
