test that electric fence

On Page 320 of my copy of PR, Cayce confronts a fence that may be electrified -- "She extends her finger. Takes a breath. Taps the chain link as lightly, as quickly as she can. No shock..."
If you ever need to do this, you must touch the wire with the BACK of your hand -- old electrician's trick for testing live wires. If there is a shock, the muscle reflex will jerk your hand BACKWARDS, off the wire. If you "tap", and there's a shock, the reflex will jerk your hand towards the wire, and you will be unable to withdraw it and you will fry. Here's something from the net:
"When the time comes to actually make contact with the conductor(s) of a supposedly dead power system, do so first with the back of one hand, so that if a shock should occur, the muscle reaction will pull the fingers away from the conductor.

The guy who taught me this (30 years ago) said that firemen are trained to enter a burning building with the palms of their hands facing them, for just this reason -- if they run into a live wire, the reflex will jerk their hands away.

BTW, I have to say that Cayce's escape from that "prison" has to be the single most unlikely event I've ever read in fiction -- would she just be left unattended like that? But never mind, real life is much stranger than any fiction.

Intresting,thank you . Bits of info like that may one day be useful, survival wise.
You never know...

In my fire fighting practices last week we were told to touch suspicious walls and doors with the back of the hand first. The theory being that even if it is scorching hot, the hand will not be crippled.

Although I prefer being in a three person firehose team in water-wall mode.

Two things:

The energisers of most electric fences work on pulses - instead of constantly running 50000 volts through the wire, they might only pulse it through every second or so. Or if the fence is especially big, maybe even every five seconds or more - as long as it's a shorter interval than the time it'd take to climb. Save's power, and decreases the wear on the circuitry. I'd reckon Cayce would be able to keep her contact as brief as about a tenth of a second, if that.

Secondly, a better way of checking is to rouch it with a blade of grass. There's enough resistance in it to drop the jolt down to about a tingle, and if you hand does clench, the motion would be enough to jerk the blade away from the fence.

Or, just cut a hole through with your laser knife.

Or laser eyes, if you have them.

My oh my, if there isn't a confirmation of a hypothesis or two in that old album.

Since no one else bothered: The prison is described as being a place where people actually try to break IN to. The fence was only erected to stop the locals from pillageing the campus. If they are more worried about keeping people out than in, it'd be fairly simple to esacpe. Most people who are in that particular prison are probably much better off inside than almost anything they could achieve on the outside. They are basically working for Pixar Russia settled in a safe hole in the middle of of a toxic waste spill. Who wants to leave and go through that?

Kind of gross but-
How about just spitting into it?
Would it go Spifff!?

Nope. The electric fence usually needs some sort of path to an earth ground to work. You tend to short much better than the insulators that space the fence from the posts. Smile If you grab the fence with one hand and hang in midair, you shouldn't feel much, excapt maybe in that one hand. But, if you hang with both arms you might get a shock as your body becomes a path for current from one hand to the other. The spit would just sit there until it dripped off or dried up. I don't think an electric fence uses enough amperage to do much to a wad of spit unless it is a killer level fence. I suppose I could go test but my parents ranch and their electric fence is about 30mins away... Wink

My point: she arrives at this place unconscious, how is she supposed to know where on earth she is? She is carrying information that might seriously compromise the security of this entire vast business empire, but she's left completely unattended -- hello? I know there are two different security camps in this organisation, but unless someone ran some serious interference, why was no one watching anything she did, after she regained consciousness and was fed? She is just left to her own devices and wanders off? Doesn't make sense to me, but the image of her wandering in that wasteland makes it work.

Please don't piss on any electric fences, I don't want to think about it. The standard electrician's pose (taught by Nikola Tesla, who knew what he was talking about) is that you keep one hand in your pocket whenever you're dealing with high tension apparatus, so that you don't get a current passing from one arm to the other across your heart, which will kill you. The idea of hanging on the wire by one hand -- there is still a very steep potential gradient towards the ground, you will still fry. Powerline workers who clip themselves to a high-tension cable, thus charging themselves up to the same voltage, approach the cable HORIZONTALLY, so as not to fall victim to the potential gradient towards the ground. This lets them work on the cable without switching the power off. Do not try this at home.

If I was you I'd follow the advice of Ren and Stimpy;

DONT WIZZ ON THE ELECTRIC FENCE!!

When nature's callin'
Don't be stallin'
Use your common sense
Before your let if flow
Find a place to go
Just don't whiz on the electric fence
If you're gonna explode
You can use the commode
of igloos, cave dwellings or tents
No need to explain when you gotta drain
Just don't whiz on the electric fence
You can swizzle on the sofa
Piddle in the air
Tinkle in the toilet
That's why it is there
You can let in rain
In the breakfast lane
While waving at ladies and gents
Just don't whiz on...
Don't whiz on
Don't whiz on the electric fence

Just as long as your bursts are short enough, you should be safe. The further your range, the longer the bursts...

In my extreme youth, like Three or four, I was leaving the pasture closest to my Grandparents farm house when I recieved a " short, sharp, shock". Outraged and full of three year old Girl fury I turned around and Slapped that fence but hard, (again and again) thinking I was gonna get my own back? I dunno, But I kept at it enraged till my grandpa drug me away saying,
"Honey, that's one fight your not going to win." when he let go of me I ran right back up the hill. Looked at the fence .. Gave it my meanest look...

Um... I think Ren and Stimpy win this thread... I sure hope so...

While on the subject, an old radio man was telling me a few weeks ago about how you get a new antenna to perform to spec when the authorities come out to measure for interference etc. One of the biggest problems is getting a good ground connection, especially in dry areas. So what you do is take a good long leak over the earth lead, and everything radiates fine for the inspectors. You just gotta know when to go.

Have you seen cellphone masts disguised as trees? There may be a reason. I found this on a radio ham site:

"Note that the ground qualities will enhance automatically by using such an treetenna. That is because most all dogs will stop and urinate
against the base of said device. Add a few beer drinking buddies to the party, and you will be a dx chipper in no time."
http://www.ibiblio.org/pub/academic/agriculture/agronomy/ham/ANTENNAS/20040524.ant

But I am still wondering how Cayce ended up wandering in that titanium wasteland. If you read Len Deighton you know that sometimes the best way to keep someone safe is to allow them to go completely walkabout, so that no one (least of all them themselves) has the faintest idea where they are. Is that what happened?
