Welcome to this professional technical forum! Lightning Protection/Safety & Keraunic (shock) Medicine is a moderated list. WE DISCUSS: protecting people, electronics and structures from lightning, and the treatment and effects of electric shock. Some areas discussed are Lightning safety; Boating safety; Grounding and testing/maintenance; Home protection; Broadcast towers; Fraudulent claims and specifications; Educating meteorologists, teachers, public safety personnel in accurate lightning facts and safety.

CO-MODERATORS and LIST MEMBERS include recognized experts who generously give their time in fostering accurate information and, especially, saving lives (lightning safety).

THIS LIST IS NOT a substitute for correctly solving site problems. That requires hiring (i.e., paying) a qualified, experienced power quality Electrical Engineer (E.E.) or Professional Engineer (P.E.)! We like hearing about difficult situations and scientifically proven effective solutions.
