How far from a marked utility can you safely dig with a machine?

The correct distance to safely dig with a machine, measured from a marked utility, is 18 inches to either side of the mark. This guideline is designed to provide a buffer zone to minimize the risk of damaging underground utilities while still allowing for effective excavation work. Understanding this safe digging distance is crucial for preventing accidents that could lead to service disruptions, personal injuries, or costly repairs.

The 18-inch buffer takes into account the varying depths and placements of different types of utilities, ensuring that workers have a reasonable margin for safety without overreaching into areas where utilities may be located. It's important to always check local regulations and utility company guidelines, as there might be more specific instructions depending on the type of utility and the region.
