What would the risk be of electrocution caused by a lightning strike of a metal home elevated by wooden piles? The entire home's structure is metal (galvanized steel roof, aluminum subroof, aluminum walls, galvanized steel floor. The wooden piles are approximately 8 feet above ground, over 15 feet below ground, the diameter of each pile is around 12". There are wooden beams between the floor and the piles, the beams are attached to the piles with galvanized steel brackets.
My main concern was the safety of someone standing on the metal floor, let's say barefooted, during the event of a lightning strike.
