Lightning safety systems are made first and foremost as fire security methods – to stop the constructing from burning down and getting rid of the people today and products within. Bringing metallic services right into a structure delivers paths for lightning to abide by from the skin atmosphere to generate hazards in. We bond or interconnect grounds and pipes for the lightning safety system to stay away from a portion of this problem. The following phase is to supply safety on circuits affiliated with electrical, interaction, and/or facts strains that could transmit lightning into a framework.
