Before You Dig
Steps to Safe Digging
Safe digging is everyone’s responsibility, but excavators have more responsibilities under the law and higher risk if the proper processes aren’t followed. Submitting a ticket is the first step but it’s not the only step, and sometimes it takes more than just the one call.
Uniform Color Code
The uniform color code is used for marking excavation sites and underground facilities in conflict with an excavation.
Underground facilities may be marked on the ground in either paint, stakes, or flags.
Tolerance or Safety Zone
Tennessee state law requires excavators to exercise reasonable care when working inside the tolerance or safety zone. The tolerance zone is the width of the buried facility plus two (2) feet (or 24 inches) on each side.
