What is the minimum distance to keep from a marked utility line when digging?

The minimum distance to keep from a marked utility line when digging is 18 inches. This distance is crucial for ensuring the safety of workers and the integrity of the utility lines. Digging too close to a utility line can lead to accidental damage, which may result in dangerous situations, service disruptions, or costly repairs.

Maintaining an 18-inch buffer allows for a safer excavation zone, accommodating any potential shifts in the location of utility lines, as well as ensuring that locate markings—often a few inches in accuracy—are respected. This practice is part of standard safety protocols in excavation and construction to minimize risks and maintain compliance with regulations governing the handling of utility lines.
