Re: C
The "What if ... ?" aspect of destructive testing was one of my favorite games for several years. I've measured 115,000V after running a standard vacuum cleaner over the floor of a SillyConValley shipping & receiving department. Lots of very small particles moving quickly through a plastic tube caused the static buildup. The next stop on the cleaner's schedule was the stockroom, with shelves & shelves full of static sensitive parts. Much hilarity ensued.
I once measured 61,750ish volts on an empty, unused Styrofoam coffee cup set down on an isolated table after a colleague walked across a nylon carpet wearing Nikes ... Was an example, just to prove the point.
In other news, the average secretary can generate upwards of 85KV walking down the hall to get a cuppa, but myself walking alongside her came up static free. Seems my unmentionables were made of cotton, hers were made of petrochemicals. Her heels were leather, my soles were high-carbon rubber.
Along the same lines as the above, most gas(petrol) station pump fires seem to be caused by females with man-made fiber underwear getting back into their cars after starting the fuel flow ... and then not grounding themselves before getting close to the fumes surrounding the fuel-flap when completing the scenario. (Yes, in the enlightened state of California, we're actually allowed to fuel our own cars! Don't you wish your government trusted you as much?)
