Ok, I just had this idea that I didn't do enough on safety, relying too heavily on QADV, so I whipped out the IRTS disk and did a bit more study. A few interesting things turned up.
One is that the human body has a low resistance, of around 500 ohms. Voltages of as little as 30 to 50 volts can kill, but it's the current that usually does the job. Remember this:
"It's the volts that jolt and the mils that kill". That should help you remember it.
If you have to ground something for lightning strikes, make sure the rods are between 5 and 8 feet long.
Oh, and if you need to stay a mast, it must be stayed at a height of 60-80% of its overall height.
