It may not always be possible to protect the pole top worker and the ground worker simultaneously.  For example: placing an earth rod at the base of the pole and the inclusion of a personal earth, provides the pole worker with protection, but leaves the ground workers in a danger zone. However, if the earth rod is moved away from the base of the pole to protect ground workers, the pole top worker without a personal esarth has lost protection.

GROUND WORKERS IN DANGER ZONE

Grounding a network cannot prevent the ground becoming energised from multiple uncontrolled energy sources such as induced voltage, lightning strikes, earth faults and inadequate earthing methods.

REMEMBER…….Grounding a Network does not make the work site safe.
