Part 36 Mining

Section 570 Grounding

Subsection 570(1)

Continued integrity of the ground electrodes is essential to the safety of the electrical system and workers.

Inspection and testing of ground electrodes ensures that the system is properly maintained and operated Ground resistance must be maintained at its lowest possible level. Normal oxidation or other causes may affect the measured resistance value. Electrical current leaks can occur as a result of deteriorating cable insulation or when an energized line comes into contact with another path to ground. Grounding prevents equipment and cables from becoming a serious threat to the safety of workers.

Subsection 570(2)

Records must be maintained and kept for two years. An officer may request the records to confirm compliance with this section.
