Individual radial or vertical earth electrodes bonded to each down-conductor.
While IEC 62305-4 covers SPDs in detail for electronics, Part 3 requires the installation of SPDs at the entrance of power and signal lines to prevent physical damage and fire caused by lightning currents entering the building via service lines. iec 62305-3 pdf

Down-conductors provide low-impedance parallel paths from the roof to the ground. Multiple parallel paths are required to divide the lightning current, reduce localized heating, and minimize internal electromagnetic interference.
Facilities with high explosion hazards require comprehensive testing every single year. Conclusion: Utilizing the Standard
The standard is a comprehensive framework for engineering effective physical lightning protection systems. By utilizing proper air-terminations, properly spaced down-conductors, robust grounding, and calculated equipotential bonding, designers can heavily reduce structural damage and life safety hazards.
