Can anyone tell me the proper way to ground flammable storage cabinets, ie) coldwater pipes (if so, must you jumper all the valves), structural steel, ground rods, etc.? What is permitted and what is not permitted...per the the NFPA? The NEC says to refer to NFPA 30.5.6.3.4 and 5.6.3.5 flammable and combustible liquids code. I've googled numerous times but I've yet to find what I'm looking for. Thank you in advance.
