We have gas lines that run across the attic. We had a lightning protection system installed, which includes properly grounding the gas lines and the gas main. Having witnessed a fire that took out a house (lightning strike and gas lines in the attic) we decided the investment in the LPS was worthwhile. Turns out, just about every municipal building and even skyscrapers all have them. Even the fire house on the corner of Bonita and Buena Vista.
