. . . and I think that sums it up -- if you are running PW conventional (as we both are), I doubt there's anything to worry about. OTOH, if you run and handle anything with a circuit board or other modern electronics, taking steps to avoid and/or discharge any static buildup would probably be prudent, as others have documented.
