What is the recommended distance marking relative to the pipeline?

The recommendation of marking the distance from the center line of the pipeline, specifically 3 feet, is based on industry safety standards and practices. This distance is established to ensure that markers are adequately visible and accessible, providing an effective warning to prevent accidental digging or damage to the pipeline. Marking at this distance helps maintenance crews and excavation operators to identify the pipeline location accurately while also maintaining a safe working environment.

By using the center line for reference, it creates a standardized method for pipeline identification that can be applied consistently across various locations. This practice minimizes the risk of accidents associated with inadvertent excavation and fosters better coordination during maintenance and construction activities.
