Here is a story that was in the ADN today.
This unfortunate gentleman appears to have lost his life because of working around energized circuits.
Remember to disconnect your battery and/or shore power before working on ANY electrical or electrical connected work. A dead circuit never killed anyone.
If you have to work on a "live" circuit, Remove ALL your jewelry, rings, watches etc.
Safety has to be number 1. Although this gentleman died, it didn't have to be this way. It only takes ONE time and you are dead forever!
"Respect electricity" and you will LIVE!
