This British Standard provides guidance on the design of systems for the protection of structures against lightning and on the selection of materials. Recommendations are made for special cases such as explosives stores and temporary structures, e.g. cranes and spectator stands constructed of metal scaffolding. Guidance is also given on the protection of electronically stored data.
The principle informing all the provisions of this British Standard is that of the "Faraday cage" form of lightning protection, and installations employing alternative technologies fall outside the scope of this British Standard.
Protection of offshore oil and gas installations does not fall within the scope of this British Standard.
NOTE Where current-carrying conductors are directly associated with structures lying within the scope of this code of practice, certain recommendations relating to them are included; however, the protection of radar stations, overhead telephone wires, electric traction and supply lines should, on account of their special nature, be determined by the appropriate authorities.
