Poor earthing welding hazard
WebJun 29, 2024 · The “path” or the earthing system is installed from the top to the bottom of the building. The conductor provides a poor resistance path between the top of the conductor rod – through a substantial metal strip – to the ground. Hence the current from the lightning strike is diverted through the rod and avoids flowing through the building. WebManaging Electrical Risks in the Workplace - Safe Work Australia
