I worked on electronics for the military, one of which was a giant 2000 Watt HF amplifier that was stock to a MRC-148. When we got new Marines one of the first things we'd show them was when you remove the cover, turn the lights off, and have a florescent light bulb nearby it will activate. The purpose was to demonstrate the distance which electricity, unabated can travel. That was followed by explaining:
- Always ground yourself to an actual building rod or a rod planted at least six feet deep.
- Lock out, tag out everything. Our tools were metal, go work on ONE truck with a battery array without an extension and you will almost certainly arc something.
- Voltage isn't what kills. It takes an insanely low amount of amperage to stop a heart.
- Always have another person nearby with a wood or rubberized object to disconnect the circuit. Being stuck being electrocuted is a surprisingly slow death that you will be entirely conscious for.
