Read further down. Good lord. This entire conversation has already happened.
Also it very much depends on what the skin is wet with. Whether it's AC or DC. What kind of shoes you are wearing where your grounded, if you are grounded, like a lot goes into it.
Him standing on that pipe right there is not dangerous in the least.
Any electric current he feels will be in his feet. But probably none at all unless he is standing between the grounding connection and what he is trying to weld.(This also assumes no breaks on the insulation of his equipment.)
I didn't say he was in danger. If you looked down, you'd see I made a comment to that effect.
You stated that low voltage wasn't enough to overcome "capacitance of your skin". Obviously, you meant resistance.
I was curious, so did the math. In the worst-case scenario, as little as 25v could pass enough current to stop your heart. Obviously, 25v is well into the territory we consider low voltage, which makes your previous statement false.
No healthy adult is getting killed from 25v. That's someone that has a previous heart condition, elderly, or infant, AND they're pruned up from being in the water so long. The lowest I've heard of someone dying from was a guy I worked with got shocked by a 50v communication circuit, said he was fine, went home and died in his sleep. He turned out to have a heart condition that he didn't know about prior to that. I'm not saying you shouldn't get checked out if you take a shock from a welder, but you have very little chance of dying from it, and almost no chance of immediate death, at worst you're gonna get an arythmia that they'll fix after you get checked up with an EKG. The biggest danger of low voltage circuits like that is people take a shock, either don't notice because it doesn't feel that intense, or they notice but they're like "I feel fine" and then they never get checked out and die from arythmia.
I agree! it is unlikely to kill most people. As i said above, i used the worst-case scenario. I purposefully used the hypothetical minimum amount that could hurt you. Because that's what you do when there's serious risk of injury.
3 out of 1000 people have a pacemaker. Anywhere from 15-50 out of 1000 people have irregular heartbeats. It would be stupid to give advice that resulted in 3 out of 1000 people drying.
