Savasa- If I can slip this link in I think it will explain much better than I could.

This does not mean that one could not be electrocuted in SW. Many years ago I was hired by the company building the new terminal facilities for the ferry company serving The Vineyard and Nantucket. Just after I gotten out of the water from running non-energized u/w cables to the ferry landing dolphin lights (in January) another diver died u/w of electrocution. Not sure of the details but I think it was quite possibly related to u/w welding tasks which would create substantially greater risk potential than pictured above and may have involved direct contact with fatal power source in an electrolyte environment.
