Multiple Work Locations and Single-Phase Grounding at Work Location

potential, eliminating the possibility of the lineworker getting in series to ground. [See 29 CFR

1910.269(n)(3)].

7.5.6.2 MULTIPLE WORK LOCATIONS AND SINGLE-PHASE GROUNDING AT

WORK LOCATION

If work is to be performed at more than one place in a line section, the line section shall be grounded

at one location and the conductor be grounded at each work location to reduce the potential voltage

difference across the work site.

7.5.6.3 OTHER LOCATIONS

Grounds shall be placed at the work location or at each side of the work location and as close as

practical to it.

7.5.7 TESTING WITHOUT GROUNDS

Grounds may be temporarily removed when necessary for testing. Each employee shall use

insulating equipment and be isolated from any hazard involved. Additional measures may be

necessary to protect each exposed employee in case previously grounded lines or equipment become

energized [See 29 CFR 1910.269(n)(9)].

7.5.8 GROUND PERSONNEL

In cases where ground rods or pole grounds are used for personal protective grounding, personnel

working on the ground shall either maintain a safe distance from such equipment or use the

appropriate equipment designed to prevent touch-and-step potential hazards. The term "touch

potential hazard" refers to the difference in voltage measured between the grounding equipment and

a worker in contact with the grounding equipment at the time it is accidentally energized. The term

"step potential hazard" refers to the difference in voltage measured between each foot of the worker

standing or walking in an electrical field created by high voltage brought to earth (See 29 CFR

1910.269, Appendix C and IEEE 80 for further information).

7.6 INSTALLING OR REMOVING CONDUCTORS

Employees installing or removing conductors should follow certain guidelines to ensure safety.

7.6.1 WORKING ON ENERGIZED LINE OR EQUIPMENT

Employees working on energized lines or equipment should comply with the following:

1. Work on electrical equipment and circuits other than electrical utility lines and equipment,

operating a 50 V or more ground, should be worked on following the guidelines of Section 2

of the handbook.
