Posted by Mr. Bitey I seem to remember the 6mA as well from college (B.S. in E.E). I also remember an instructor telling us a 9v battery could stop your heart from arm to arm, provided you pierce the skin with a couple of needles and use them as contact points.... o.O

A 9 volt battery delivers a lot more than 6 ma probably in the 60-120 ma range.

Posted by Rustndust I think that's one of the proposed uses of the Baghdad battery.

Never really thought about what the Baghdad Battery may have been used for, but that definitely makes sense!! They probably could have even used it to make a heart beat after it had been removed from the body!! They were some crafty effers, that's for sure!

Probably for metal electroplating which could be verified by plated artifacts if so.

That was the other big thought they had rolling around /\/\

Apparently no electroplated artifacts have ever been found from this era.

I'm going to weigh in here. Do not take my advice, I'm not an electrician (yet, fingers crossed for my interview coming up in a few months) nor a doctor and this is for informational purposes only.

Resistance is one of the fundamental properties of electricity. According to NIOSH, the resistivity of dry skin is between 100k to 600k ohms. 110 volts/100k ohms = 1.1 mA of current. Ohms law tells us this, which is voltage = current * resistance.

I did some digging and came back with this page from an electric fence company
https://www.agrise...ety-risk-to-humans

To summarize their website,
-Their electric fences put out 7000 volts
-Pulses are for 1/300th of a second, spaced one second apart (giving someone time to react before getting shocked again)
-Most units have a maximum current output of between 100-150 mA

Back to ohm's law: 7000v/100k ohms = .07A or 70 mA.

Now a page from Ohio State University describes the following:
https://www.physic...fatal_current.html

Above 10mA and below 100mA, you won't be able to let go, and breathing will become difficult. But the shock is only for 1/300th of a second so you won't really be affected by these. Since it's only 70mA you shouldn't go into V-FIB.

So really, looking at the date touching an electric fence hurts but won't really harm you. That being said, if you have any sort of heart issue, or you touch the fence with your head you could be in severe danger. If there's an electric fence, find another way around it. Don't risk your life.

I've hit this place, it's mostly gutted but you can come away with some
nice shots if you take your time. It does have security as they rode
by while I was inside...

You think a taser feels bad? 7KV @70 MA will feel a lot worse.

These electric fence specs are meant to repel large animals with thick fur not humans. If the grass or you are wet the shock hazard also increases a lot.
If you're holding onto an earth grounded stake, pole, whatever and touch the fence... you'll get some religion.

That said I think a lot of these fences are putting out a lot less voltage and current than they are rated due to leakage. Who knows?

Yeah I've tried them and gotten hit. It sucks lol! And I HAVE an electrical heart condition sooo.....

I think it's fairly safe to boil the discussion down to a collective shrug and a it *probably* won't do permanent damage, but it WILL suck though!

Sorry to rehash my own post...but I wanted to show the pic that makes me wonder if infiltration (or at least fence crossing) is even worth considering...

Those wires running along the length of the fence are definitely the electrified ones, and it looks like there's multiple so that the current can't be disrupted by damage to a single wire. Not sure what "alarmed" means though- I highly doubt the fence has pressure sensors to detect touch, but periodically placed motion detectors are a possibility- or maybe "alarmed" is being used as a scary synonym for "live." It's hard to say.

Can't verify unless I saw it in person, but it *looks* like the electrified portion has been trampled by the non electrified chain link section. This would render the electrified section inoperable with the chain link dumping all of the current to ground.

Like I said I can't guarantee that but it looks like it's dead to me.

Short it out. Sparks? Leave shunt in place if no sparks.
Either way fall back and see if anything happens.
Can't tell if/how the wires are insulated.
Could simply be a proximity alarm... never saw one before though that used wire.

Unless there is something wrong with your heart, it won't kill you. People are afraid to let their kids play football today in this pussed up world. People go to jail for shooting a burgler (Texas can disregard that one). In some areas, you can't even smoke outside. People protest CLEAN energy. Can you imagine the backlash of a deadly electric fence in your neighborhood? I seriously would just touch it. Use one hand. The fear is more in the anticipation. After its done, if you get zapped, you will probably laugh and dare your buddy to do the same.

I question whether it was ever truly electrified. That sign seems awful cheesy and generic.....

Climbing fences is dicey.
Getting hung up on a chain link fence is no joke.
Those electric fence's can deliver 65+ more milliamps than a taser.
Losing voluntary control of your muscles at the wrong moment could get you KIA or seriously hurt.

♤Shunt it out with a jumper wire if you're hell bent on scaling it♤

I definitely wouldn't climb it! Was speaking more of dashing across the fallen portion in the OP's pic. I have grabbed a hold of electric fences before. While they can deliver enough current to kill you, unless it is across your heart (through both hands) and contact is made under your skin, chances are greatly in your favor....

I was in a hospital for a few months when I was 15ish. My roommate and I would challenge each other to see who could hold onto the outlet with the broken cover plate the longest. God damn kids are dumb. I don't remember who won. Probably him - he was a crazy effer. RIP Craig "2 footer" Bauer.

First off, I want to say thanks for all your input and advice...I rather wonder myself if it's even electrified anymore, especially with the fallen over part. Didn't see/hear any sparking or electric sounds, but that could mean nothing.
Eventually I'll return and check it out, but NO WAY am I going to attempt to climb it. I would think (but not sure) laying a piece of plywood or something over it would protect me...but of course it always comes back to: if it doesn't work, it could end very badly. I'll figure something out, even if that means letting it go...and I'll keep you all posted. Thanks again!

Best to breach chain link fences at a gate, corner, or a fence post near a tree or telephone pole if you can. Go under if it's doable.
Take the easiest, safest route.
Be wary of one's that aren't tight, these are the most dangerous because it's easier to get hung up on them. The fence pole must be stable and the chain link well secured.

Just the chain link alone can rip your leg or nut sack open.
Been there, done it and barely got away with it. Ended up throwing myself off after being caught on it like a fish on a hook, landing on my back on the brush.
Fortunately only my pants got shredded... fun times.

Posted by blackhawk Just the chain link alone can rip your leg or nut sack open

Ripped my leg open more than once on a fence. Let me tell you - even if you don't hit the femoral artery, your inner thigh bleeds like a m'er f'er. The last time my shoe even had blood in it....


fortunately my do-dads have never experienced sack rippage....
