I once got zapped from a 120 volt source, even though my other hand was not touching anything, and I was wearing white rubber sole running shoes. I then realized, however, that I had been leaning against a steel tool cart, and was wearing jeans pants. Apparently, the jeans were not enough insulation to prevent the shock.
220 volts and still here lucky I've heard of guys getting bold over on less one being a child putting his tongue on a 9 volt battery something to do with hart phase ? any way maybe time to close the shop for a couple of days to recuperate in a casino there may be some surplus luck still hanging around

In Canada, the water is so clean and pure that it's not conductive. We keep it stored as hemispherical shells. When you want a drink, you just bring a candle close to the wall and collect the drips in your mitt. German water, on the other hand, has so much carbon in it it's considered an alloy. It's stored primarily in brown glass flasks which look very much like beer bottles, and it has to be tested often. Itsch konductif.
Well, it's addictive anyway.
I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

They say... (no, I'm not going to test the theory) that a 50ma current through the heart is the killer. Less and it's kind of fun, more and you start cooking but don't necessarily wind up dead. At that "fatal current," your heart starts fibrillating and, well, that's not a good thing. That's "CLEAR! - WHAP!" territory. Higher current will cause more tissue damage and that damage may get severe enough to kill you. But, there's a spike in fatality at 50ma, and that's not a lot of current.
In electronics, we were taught to use one hand only. You may screw up. lean against something, and get zapped. But, it's unlikely to go arm to arm through your heart. Again, just book knowledge, and I aim to keep it that way.
I don't know how it is in the USA or UK or Europe, but in OZ if any shop is or is part of a commercial/industrial enterprise, all electric tools (hand tools included) have to be tested by an OHS ("WorkSafe" here) licenced Electrician and "tagged" as OK for use it it passes or a "Do NOt Use" tag applied for non-conforming machines.
Extension leads are included.
Testing is mandatory and annual or after a machine or toll has been repaired as ready for use.
Having or using non-tagged or "Do Not Use" machines is best described as liable to prosecution.

That depends on the type of shop that they are in , I dont have to tag any that I am using for test as long as they do not leave the workshop, and are only used under strictly controlled conditions , eg no visitors or lending to anyone .
I even have what is referred to as death leads again only to be used in shop for testing repaired equipment ,there is an earth leakage on each circuit and the main box is also fitted with the compulsory unit which I specified to be only 30ma trip current .
I think it is far better to get annoying trips than be carted off in a box.
However all equipment that even may go outside for any work purpose has to be regularly tested and tagged.
I asked before getting into trouble with the electrical authorities.

Tiffie is right, Australian's are total pansies when it comes to mains electricity... I cannot even connect 3 coloured coded wires to a plug.. If you do do that and have not done the required four years mandatory training, they will send you to jail...
Here in the States, (well, most of them) they still think the average citizen is capable of electricity.
I built and wired two houses, my own, requiring only a desultory inspection by questionable public officials. (I have seen some pretty shabby work elsewhere approved by the same official). I was also self-employed for almost 20 years, wiring control panels and machine tools, all legal, all without benefit of license or certificate. Only got minor zapped twice in the process.
That is not to say that I have anything against the licensed electrician, and BF is wise to have one in to look at his situation.

The electrician can not come today. I tested the ground fault breaker by shorting across the leads and it triped fine. I put my cable inside last night for it to dry. This morning I had no electricity on the frame. I tested it with one of those screwdrivers that light up. Nothing. So I touched the frame with my finger. Nothing.
I had a tough night but now I am feeling better and not so much swelling. When the electrician comes I will have him change the breaker even though it seems to be working correctly.
