Jobsites are classified according to the underground hazards present, not by the line
being installed. A jobsite may have more than one classification.

electric utilities exists.
Once classified, take precautions appropriate for the jobsite. Follow the US Department of
Labor regulations on excavating and trenching (Part 1926, Subpart P) and other similar
regulations.
