Electricians - an awkward bunch to deal with

Now, the TREMENDOUS pain you will feel in you "entire arm" is profoundly different from a AC voltage pain , like temporary licking on a 240 outlet.

How afraid should we all be?

Ask the electrician who told me this story.

Why are people so worried about 230V mains?
It's only a thump. Doesn't really hurt that much.
So far the calibrator has caught me with 1kV DC but no real current, I pressed the standby button but pulled the leads before it had ramped down. The PAT tester test box got me once with 230 from the mains, I had chosen to use unshielded test leads as the others kept popping out, I unplugged from the test meter before the test box. The best so far was a flash tester that had the foot switch shorted and unknown to me it was on and set to 13kV, I leant over a steel table to plug it in, damn that gave me a thump. At home I isolate and test before touching stuff but it's easy at work to forget the stuff I am dealing with as we are normally well protected from the dangers.

well, its been known for killing people occasionally ::)

Even 120 VAC mains in North America have been known to be lethal.
