(a) Calculate the overall Risk factor for Lightning Protection for Factory Buildings. Given this building is constructed in reinforced concrete with a metal roof. Given the dimensions of the Buildings as listed and the number of flashes to ground per km squared per year (Ng) is 0.6. Justified your result whether lightning protection is needed for this Building.
(b) The business of the factory is the production of canned food. Explain your design whether the Lightning protection of this Building shall be designed in Isolated and Non-isolated type.
