For a work area, how should warning signs be placed relative to the working limits?

Placing warning signs at least 2 miles away from the working limits is essential for providing adequate warning to approaching trains and workers about potential hazards in the area. This distance ensures that individuals have sufficient time to react appropriately to the presence of any work activities, allowing for safe navigation around the work zone.

Establishing a buffer zone with warning signs at this distance helps to create a clear visual alert that is noticeable well in advance. It also aligns with safety protocols and guidelines that prioritize the protection of both workers on-site and the train crews. This practice minimizes the risk of accidents by alerting everyone well before they reach a potential danger zone.
