Maybe it triggered an existing condition.
Six months later he suffered a heart attack.

An immediate EKG may not have shown anything, but a follow-up by a
cardiologist might have shown problems.

From my own experiance, rf burns hurt more than
standard 50Hz ac or dc shocks even though I would have to
rate car iginition systems a close second.

RF frequency burns are nastier than DC or low frequency, and are much
more disruptive to the body's electrical/nervous system.

They can also burn internally, with little outward burn shown.

A co-worker some years ago was sloppy, and put a few hundred watts of
RF through his hand. Nasty burn which took a very long time to heal.
Over 15 years, but I bet he still has a scar.

My advice is to avoid zapping anything you can't buy at the parts
store.

Happy trails,

The question seems daft, but bear with me, gentlemen. Has anyone ever
had an electric shock that they feel lucky to have survived?
=20


One of the guys on a maintenance crew I was on in a previous job
and was doing testing with managed to get a nice 415vac 400Hz
across the chest.

Doing testing in mec relay panel the relays were in the back of the =
panel / box and
the doors are where all the circuit breakers are mounted.
remeber he made contact with the uncovered terminal of a transformer.

I was working with him as well as a few others, activating =
sensors(sticking a spanner in front etc)
and he was confirming the right voltages were being recieved to activate =
relays etc.
Just heard a loud shout over the intercom and we all went running.

He was lucky he didn't get throw by it as he could have fallen about=20
10 foot on to the tarmac.

Just stunned at the time. Had to take him for a ecg afterwards
standard precaution. No problems at the time.

For a moment there I thought you were about to tell us you were

of spark plugs for my Diesel lorry and a couple of
skyhooks to hold up my HF dipole!
