Power earthing lays the foundation for a compliant and comprehensive electrical safety system. In this episode, Omega Red’s Dave Willets joins host Nick Marshall to unpack why earthing matters, reveal the hidden hazards that often go unnoticed, and break down the key components that make an earthing system truly effective.

This includes:

• Engineering fundamentals and risk factors of power earthing
• Key safety functions of power earthing
• Importance of managing fault currents
• Core risks that earthing design must mitigate
• Earth Potential Rise (EPR), touch potential, step potential and transfer potential
• Earthing design for large contracts and key inputs
• Shift from resistance-based design to voltage-based safety criteria
• Factors for successful system execution and set-up
• Commonly overlooked areas in power earthing and why projects often go wrong

We trace the shift from improvised rooftop systems to rigorous, evidence-led height safety with BS 7883:2019 and BS 8681. In this episode, Omega Red's Tim Lee chats to host Nick Marshall and explains how to spot real competence, what good documentation looks like and why restraint and collective protection should lead design choices.

This includes:

• Evolution from 1997 anchors to system-based design
• Why restraint beats fall arrest for routine tasks
• Addressing fragile skylights and pendulum risks
• Technology shifts: load-limiting posts and membranes
• 2019 changes: named designer and documentation
• Retrospective compliance and uncovering hidden fixings
• Competence under BS 8681 and manufacturer approvals
• What good looks like in reports and technical files
• Rooftop strategy with PV arrays and edge protection
• Client due diligence and accountability across the supply chain
