• Fixing of earth tapes and connections of tapes and cables as per design drawings
• Connection to earthing networks / systems installed by others.
• Any labelling required for tapes and cables

To undertake a lightning protection risk assessment in accordance with the requirements set out within BS EN 62305, the lighting protection risk assessment shall

intervention shaft or firefighting point.

To use conductor tapes, running down the exterior of the building to separate earth rods, in preference to using structural steelwork where practicable to minimise the risk to sensitive equipment.

To ensures that all cables running externally shall make as much use as practicable of natural shielding from fully bonded conducting materials.

To assesses the lightning protection system for the incorporation of air termination networks on the roof and identify that best composition.

To provide test joints for all down and earthing conductors and will be located in inspection pits adjacent to the above ground building foundations.

To install surge protection devices for all cables passing through the lightning protection system and be class I type where cables enter and leave the building at roof level, conforming to IC 61643-12.

To install class III type conforming to IC 61643-12 where cables enter and leave the building at ground level surge protection devices.
