Two questions regarding lightning protection grounding in chemical plants
Thread Content
1. In steel structure factories, frame columns can be used as conductors to connect to the ground grid; so once there is electricity from lightning, wouldn’t that electricity flow through those columns as well? Aren’t the people inside quite dangerous? 2. How should tower equipment extending beyond the roof be grounded for lightning protection? Should the tower itself be used as a conductor with grounding at the base skirt, or should a separate lightning rod be installed?
Theoretically it’s possible, for safety reasons during that period
The conductivity is very fast; if it happens by chance, there’s nothing that can be done about it. The tower body is used as the conductor, with a grounding grid underground

The first question is about the author’s investigation into Faraday cages. The second question is whether the tower structure can be used as a lightning protection down conductor; this depends on the material of the tower, the properties of the materials used, and the safety requirements. For the tower extending beyond the roof, in my opinion, a lightning rod should be installed at the top of the tower; additionally, hot-dip galvanized 4*25 flat steel or No. 8 round steel should be used as down conductors to connect with the main down conductor on the roof. At the same time, the tower should be electrically connected to the building’s own grounding grid to ensure equal potential

The human body’s resistance is greater than that of metal; was it bypassed? ? :P
The entire metal frame structure forms a cage； Even if there is voltage, it is extremely small and negligible. It is recommended that for grounding, grounding flat bars be directly welded to the bottom of the tower on both sides, with the other ends connected to the grounding grid. Connection is made using M12 bolts.
