Super fast summary:-
Wet areas or ones with a lot of exposed metal pose the highest shock risk.
Confined areas or reaching into equipment pose a higher risk of fatality by trapping you during an electrical contact.
Treat everything as live even when seemingly isolated/disconnected due to the risk of backfeeds from other circuits.
Ordinary work gloves can reduce the risk of a serious shock greatly.
Safe electrical training can not be replaced with 1-5 day slideshow classes.
One thing I didn't mention in the video is the horrific way most fatal shocks occur. Workers making contact with live connections while in confined spaces or getting trapped reaching into equipment often die of oxygen starvation, as their ability to breathe and the heart's ability to pump blood is prevented by the flow of current through their body. Even when they black out they are often still passing current, and if not discovered quickly will not survive.
Gloves. If you touch an electrical connection with your bare hands, the only insulation between them and a VERY conductive interior is a layer of dead skin cells on the surface. They do not have a voltage rating and in the event of contact the skin's resistance rapidly breaks down. In the event of muscle contraction a larger area of skin makes contact and high current will flow.
While there are specifically rated live-work gloves, for less critical scenarios where you are not deliberately going to be handling live metal, a set of common work gloves adds a valuable extra layer of insulation to your hands. At the very least they can reduce the shock current of an accidental contact. The insulation of gloves is greatly reduced if they are wet.
CPR (Cardiopulmonary Resuscitation). This is a very volatile area, since every country has its own standards and there is a lot of folklore from the past.
The primary purpose of CPR (chest compressions) is to keep blood flowing around the body to prevent brain death. The theory that providing CPR to someone with a beating heart is dangerous has been disproven. Instead of wasting time trying to find a pulse, it is now considered a good option to immediately start chest compressions on an unconscious shock victim to get the existing oxygenated blood flowing to the brain. The act of compressing the chest can also cause airflow in the lungs, although the "breath of life" (mouth to mouth resuscitation) is useful if there is more than one person present.
In the event of the heart being in a state of fibrillation it is essential that it is resynced by an external defibrillator. Every second counts, as the chance of heart resync drops rapidly with time. Even when the paramedics arrive, continue doing chest compressions until told to stop.
Here's real video footage of CPR and a defibrillator being used on the victim of a pool electrocution. The fact the unit delivered a shock pulse indicates that it detected the heart was in a state of fibrillation, but still recoverable. The shock did resynchronise his heart.
NEVER work on anything electrical while standing in water, as a shock will involve massive current.
Here are some video examples of shocks, noting that I will NOT be posting excessively graphic ones, and definitely not overhead line contacts.
Worker at top left corner makes contact with conductors of a live cable he is holding. Because the current is hand to hand, he manages to drop and gets lucky when the cable follows him down, but seems to short out as he hits the floor. Note how his arms have gone up to his chest and are so rigid that his left arm barely moves when it lands on the desk.
Example of contact with grounded metalwork while working on live circuitry. Legs in contact with bare metal, gripping on with one hand and coming into contact with an electrical connection with the other, made worse by his head contacting the metal ductwork too. I don't know what the outcome of this was. The fact he fell clear increases the chance of survival. This is a grim video.
Expect the unexpected. Guy being shocked by roller shutter that becomes live is pulled clear with a scarf.
This video shows a guy getting a shock from the electrical trigger on a pressure washer (!!!).
It shows how a shock can affect part of your body, but still leave you able to do something about it. He survived.
This shows a horribly common shock scenario in the entertainment industry, sometimes caused by old or faulty tube/valve amplifiers. It results in a voltage difference between the strings of a guitar and a microphone. Note the loud squealing feedback noise when the guitar player on the left of the stage reaches up and grabs the microphone before collapsing.

This is the unofficial guide to electrocution, because by understanding the science behind electrocution, you can make informed decisions as to your working practices and how you approach some scenarios, there's a lot more information in the description down below, including anything i missed, but most importantly of all, Demonstrations in the form of links to videos where i'll provide information about what you're about to watch in those videos. I shall also warn you if the outcome was not known, some of them may be grim. So, let's start by discussing what an electric shock is: when people bridge two electrical connections, the voltage difference current will flow through their body. The connection points are usually live.

Connections which could actually be unexpected, live objects. It could be pipes, it could be just exposed random metal work that turns out to be live, but it's usually the other point. Reference is the ambient ground plane around you that ambient ground the effect the shock will have depends on how much current flows, but it usually causes pain and muscle contraction. This is because the brain normally communicates with your muscles by electrical signals, and likewise, when you touch things, the nerves send signal electrical signals back up to your brain at low current of just a few milliamps.

It will cause significant pain through stimulating those nerves, but it won't necessarily affect the control of your muscles and i would say that probably accounts for 99.99 of electric shocks, the ones where someone's working something they go ow and they snatch their hands out. It's it doesn't take much current to cause quite a notable stinging sensation in your finger. But as the current increases, you lose control of your muscles and, as is often described in fatal electrocutions, the hands grip uncontrollably onto things and it may actually prevent you from escaping from the thing you've touched. The mechanism behind that is that, because the electrical current is now overriding the signal from your brain significantly, those people that say, oh if i would get electrocuted, i would just force myself to let go.

Sometimes you can actually, if, if muscles are still operating, you can actually drop away, but in reality you have no control over the contraction of those muscles in your hand. So what actually happens is the current flow stimulates the muscles that are for closing your hand, but it also stimulates the muscles for opening the hands it stimulates them all, and the winners in that fight are the ones that close your hand because they're the strongest, because Your hands are designed for gripping, so your hands close. If the current's flowing up your arm, it will cause your arm to go up to the chest. The reason for that is because your arms are designed for lifting against gravity as opposed to pushing down you do push down a fair amount in in normal daily life, but most of the work is actually lifting up.

So that's the strongest muscles strongest muscles win in this tug of war and your arms go up to your chest. Your head will kick back your arms uh have gone up to your chest, the body, the core of your body and your legs will go rigid because that's the normal stance, the muscles are all balanced against gravity and you will go up in your tiptoes because that's The strongest muscles in your feet and at that point you'll, usually fall backwards. This is a saving grace for some people, because, if they've actually come into contact with wires, if current's flowing to the ground, uh falling back actually breaks the connection if it doesn't, if the wires are loose and they fall them down to the ground. It's a different thing: it's not pleasant! The other thing that happens uh with that current, because it's so completely uncontrolled.

It's not uncommon for significant electric shocks to cause really significant muscle damage, even a modest electric shock can it might seem you're over it. But a few days later, you'll get sort of that gym. Workout pain in your muscles they'll really hurt because they've been stressed quite significantly, but during a shock a high level shock. It can actually break bones as well, because, if you're fairly muscular, it puts all your muscles against each other uncontrollably at maximum strength.

And it's not uncommon for people who get a hand to hand shock to actually break their both their shoulder bones. The other thing that can happen is, of course, being thrown into the air. It's not the electricity, that's throwing you if you're crouching down to any level at all the current flow through your body will make your legs go rigidly straight, but completely with massive, uncontrolled force. The muscles will just be all be simultaneously driven maximum power.

Far beyond the point that you could normally control them and that's what actually tends to throw people into the air, the two i mean, those things are bad enough, but the two really undesirable bits. The bits that cause death are your heart, which every kind of knows about, but also your diaphragm. Let's start with the heart, the heart is a an organ composed larger than muscle, and it's got lots of sections and they all beat in sync to actually pump blood around the body. It's quite a resilient thing.

The heart, when the current flows through two situations can occur well, three situations if it was very low current, it might not affect it at all. If it's medium current, it might cause partial contraction of the heart, which is not good, because it can knock out of sync a kind of bad but kind of a better case scenario i believe, is uh. When enough current flows, it causes the whole heart to contract. At once, the chances are that it will regain its beat afterwards if the current path is broken because uh, the heart is actually surprisingly resilient.

It's very capable of re-synchronizing the diaphragm is an extremely unpleasant aspect of electrocution. The diaphragm is below your lungs and it normally. It's muscles that actually move up and down, and it makes your lungs inflate and deflate in the event of a significant flow of current through the diaphragm. It locks in an intermediate position, and this means that people can't scream while they're being electrocuted.

Now, if you've seen electrocution in the movies, you know what the movies tend to exaggerate things and you might think that's what electrocution actually looks like so that'll be people thrashing about and sparks and flames and buzzing and the lights all dipping in reality. That does not happen. The majority of significant electrocutions are virtually silent. You won't get any clue.

It's often said that people who have been next to people who were electrocuted said all they heard was like they were working and they heard them go. Oh just a groaning. Noise and what that was was the sudden current through the body caused their lungs to just basically go into a mid-position state and they are probably wanting to scream, but they couldn't move they couldn't breathe. They couldn't force that air out to make the scream.

So it tends to be absolutely silent and the first clues of working next to someone who's been electrocuted. Are you look at them because they've, not they don't answer a question. You say something to them and you suddenly realize that they're just locked in a fixed state on a piece of equipment in that instance uh. Obviously you need to break the circuit as quickly as possible, um and then traditionally you know.

There's that thing about get a big piece of wood and leave them off or hit them with a big stick or something like that in reality, for technical people like us uh, you immediately assess the situation. It could be as simple as flicking a switch to kill the power if power is coming from another source to an isolated piece of equipment. This is just an increasing issue with modern electrical training circuits being crossed. You can literally, you can kick them off, but keep in mind that, if someone's gripping on under full force of a current flowing through the body that the muscles will be much stronger, uh gripping much stronger than maybe you could get them off.

It depends how they're actually locked into something uh in these instances uh you could try and kick them off you. If they're stuck to a wire, you can see something you could cut it with a pair of snips. You could short something out anything to basically blow a fuse or or break that connection to get them off, and this is where uh you might find. They just dropped the ground, then they're, like they they're, they're, fully conscious and they're, obviously extremely agitated and and you at that point, i would recommend that you know you get medical attention, even if you get a shock yourself of that similar thing that really an odd Tingle's, not bad, but if you've got a real wump one that we really feel massive current flow through your body or it knocks you out, seek medical attention and here's what will happen? It's it's not really intrusive at all.

The paramedics will turn up. They will basically connect you to an ecg unit. Defibrillator is really it's all one combined unit these days. I think, and it will simply monitor your heartbeat they'll, probably put the the blood pressure monitor on your arm and maybe a blood oxymeter on your finger and they'll.

Just basically monitor you monitor you, but in most instances, if you've just picked yourself up off the floor, you have survived, and at this point it's worth seeing that there are organizations uh masquerading as safety organizations that scaremonger about electrocution and imply that you're going to die In reality, electrocution is so rare. Electrocution is where someone actually dies. It's electric execution but fatal electric shocks. Electrocution are so rare that you almost certainly make headlines in a newspaper or tv if you dive from electric shock, you're more likely to die if you're a maintenance.

Guy traveling and working on live electrical equipment to troubleshoot it on a daily basis day in day out, the chances are you're going to your chances of dying on a car crash, or a van crash are much higher than actually being electrocuted, but don't get sloppy about It, as you already know, if you've had an electric shock, it's not a pleasant experience in the first place, but suppose you come in a situation that you've just uh discovered someone who's lying on the floor or they're still in the state of being electrocuted, and you Break the circuit and they're lying the floor unconscious. Traditionally the procedure was used to be well. It still is the fact that you, if there's someone else, tell them to get medical attention immediately, tell them to call emergency services or, if you're, on your own you're supposed to do it first yourself, and they will guide you into what's actually happening. What you've to do - and just say you know, they're they've, i think they've, an electric shock, they're unconscious.

It used to be the use to say, put your finger and check for a pulse or on the wrist and check for pulse. That's out the window. Now they are basically saying now just go straight to cpr and even if you're not experiencing it, it's pressing the chest. If just central to the chest between the the nips basically press the chest, there apply decent pressure and just pump it, and this is because they've discovered that there are rumors theories that uh applying chest compression and some with a beating heart.

It could potentially stop it that turned out to be a load of crap if someone's heart is actually healthy. If it's beating applying that external pressure will not affect it will not stop their heart, but if it wasn't beating it will keep the oxygen in the blood flowing through the body, and that is the important thing keep blood flowing through the brain, because that stops the Brain from dying, it's the first bit that kind of dies really um. If there is somebody else who can provide the breath of life, then that's useful, but it's a second priority to actually getting that blood flowing um. So, let's take a look at the environments that uh are probably the most dangerous the ones where most electrocutions occur.

Now, i'm in a dry environment right now, i'm indoors i've got my crocs on i'm on carpet on wood. That's three layers of insulation already, then, that wood is on air. So that's four layers of insulation and, to be honest, my hands are dry and the outer layer of dead skin has a fairly high resistance, but it shouldn't be relied on as an electrical insulator. Obviously the most shocks occur indoors and they are coincidental some people may.

Even if i touched a live worn out, i would not get an electric shock. I wouldn't feel anything because there's no path to the current flow. In some instances, if i was leaning against a wall which was a a stone wall that was damp or if i was standing damp ground or leaning against a fridge or piece of equipment, then there is much higher risk of shock. This is where i have to say i i see so many people working in factories, factory workers that have been shown if this stops working press that reset button and they hold the door open, uh of the metal enclosure and they poke around inside they're.

Basically, holding a solid ground in their hand, don't do that if you do go into electrical panel to work, don't hold the door open with your hand, nudge it open with a dry bit of clothing. Your elbow, if you have to the other thing, is gloves. If you're working electrical stuff, even if it's dead, always play safe, i recommend gloves and they don't have to be the utility industry. Dielectric gloves those big heavy rubber gauntlets that they use to work live.

I don't recommend using gloves, like this, to routinely work on live connections and twist live connections, but if you're working on electrical equipment put your glove like this on this breathable fabric, dipped in plastic, it provides an extra layer of insulation between your skin and a dry Glove can actually protect you from getting a significant electric shock it'll. Certainly, in the case of hand, gripping onto thing, it's going to reduce the contact area of a of skin, making contact electrical connection even just like standard working gloves like this are a good choice. Mechanic style gloves, but then you get people that say: oh i've had lots of electric shocks because i've been working in dry environments and they weren't really anything special. I guess i'm immune to electric shock.

They are not. Nobody is immune to electric shock the people that present themselves that show people showing themselves get electric shocks and doing stunts. It's all fake you're, not immune to electric shock and as soon as these people go into a wet environment like working outdoors, working electrical pillars in the street working lamp posts working even in the garden on garden, a garden fountain pump, wet hands, wet ground. It changes completely suddenly what would have been just milliamps of current flowing through your body will potentially and very quickly become amps of current flowing through your body and that's when it gets very, very serious.

The most dangerous scenarios of people working are people leaning into equipment, because if they do make contact uh and their body kind of locks up, they're not gon na be able to actually pull themselves back out. They're not gon na be they might be able to just flop down the knees and flop out, but if they're actually really seriously leaning into something the chance, then being able to get out of that situation is low. The other, a major killer, is people reaching into electrical equipment reaching between components. Thinking, they're, safe they're, not you know going near anything, they touch something electrical, their arm locks in and they can't get out they're physically hooked around the metal work in the equipment, and that is an extremely dangerous scenario: don't girdle your hands in in amongst electrical equipment Like that, it's hidden connections may actually cause that situation to occur confined spaces.

Oh one of my least favorite working in tight areas where you have to shimmy in and you're on a metal surface. I'd say that to combine all these three things: large areas of exposed, metal, uh, grounded, metal, water and tight areas, some factory production equipment and food. The food industry is notorious for that. But if you're in a confined space, that's where your body may be found just use extra precaution, definitely dry gloves.

Double checking only work live if you absolutely have to more information about that down below so reducing the risk of getting a shock, obviously isolate wherever possible. Um in many instances it's not possible to isolate if you're troubleshooting equipment. I shall cover that more in the description down below bit of a sore point. Actually, there dry gloves the gloves i've mentioned can make a significant difference if you're doing routine electrical work.

It's just an extra layer of protection, even if you've isolated a circuit, it provides that extra layer as some things that occasionally happen. You see occasional, occasionally see workers that wear a glove in one hand and the bare hand the other hand for finer detailed work if they're isolated from ground that prevents a hand-to-hand shock. But it's not an official thing. It's always useful to be aware of your surrounding electrical environment.

If there is a lot of grounded metal in your vicinity, if there's water in the vicinity, it's something that traditional electricians do it used to be really beaten into us at college, to assess the electrical environment before working it and also to expect the unexpected - and this Is even more important these days now that training has been reduced between one and five days for some workers uh, as opposed to what used to be a 8 000 10 000 year apprenticeship with with full mentoring? It's i could rant about that. I shall mention that down the description down below but uh. My worst shock i've ever had was unexpected, because i was pulling a control module out of a automatic barricade holding the metal rail. Well, that's my first mistake just now.

I know i was young and it was a grounded, control box and a grounded barrier. It shouldn't have been live, i pulled it out and it wasn't live until i pulled out a bit further. It turned out that someone had removed they'd serviced the box and the circuit board inside that had all the connections on it that grounded onto the case they'd removed the brass spacer they'd lost it somewhere, so it wasn't, grounded and also they left out plastic spacers that Kept the circuit board away from the case, so it was only when i pulled out a certain length that the circuit board touched the case. I went backwards.

The circuit board went into the air. The control went into the air, went bang showers of sparks lots of people watching very embarrassing, not a good day, but expecting the unexpected, particularly things like british boilers and stuff like that. Where bad modifications to add underfloor heating can result in back feeds from other circuits, and things like that, yeah expect unexpected. This is where the gloves come in again, if you're doing electric work and probably around connections, but that is it so i definitely check the description down below.

It contains a lot more information and links to those rather undesirable videos that are very educational, but not so great for the people in them. So uh definitely check the description down below.

    When I was in the tenth grade, I completed the circuit between two poorly grounded pieces of equipment in the METALS SHOP. I didnt feel a thing, and I dont remember it at all. I just remember waking up about 20 feet from where I was. Flat on my back. Mr Cable (Indeed, Mr Cable was the electronics teacher. He was a paraplegic, in a wheel chair) had his chair rolled up over my chest, with my head between his feet. When I woke up, he was leaning down between his legs. The first words out of his mouth when I awoke, was, "BOB! THAT WAS 660V! WHAT DID THAT FEEL LIKE! DID YOU KNOW YOU CAN FLY!" I responded, "I flew? Wow."

    Reminds me of the belter I got at a pals farm off an old 3ph Oxford welder, he used to hold the rods under his arm to place them in the Lance and I used to laugh at this performance as I would renew the rods by holding them in my bare hands without incident, until one day I was welding a trailer in the pissing rain, whilst confidently changing a rod, yeah I actually heard a loud bang inside my head and found myself about 6 ft back from where I was working on my arse in a puddle of gutters totally confused as to how I got there for a few seconds, till I worked it out, like the constipated mathamatition did with a pencil. But no seriously it wasn't funny at the time.

    When i was in trade school going for my industrisl electrical maintenance tech degree my commercial electricity teacher always told us that the aside from the heart killing people, that the lungs will fill up with liquid where the bronchioles close up or burn shut causing the white blood cells to rush in trying to repsir that dead tissue but it only takes a few teaspoons of liquid in the lungs to drown you/ pneumonia.. so he would say that you could get shocked on wednesdsy and die of pneumonia on friday….

    Always keep one hand behind your back, until you know it's safe. That's all I would add. 👍

    I'm given 2 pairs of dielectric gloves per year, and have to dispose of the ones that are out of date.
    In my electronics school days, EE, I was thrown across a room after a spark jumped onto my hand. I had to stay at a nurse's office the rest of the day for monitoring. Bad safety practices will keep you from going home for dinner. Thank you for the safety talk, Clive! Safety is a big part of surviving modern machinery construction and repair.

    I was once working on a old 1950s radio cabinet and didn't notice a lightning storm creaping up.
    Lightning struck the building wall outside where I was, it ran down the electric line in the wall and some of the bolt jumped from the near by outlet to me.
    Woke up about 20mins later, burns on my side, all the way down my arm and a very fried radio.

  6. Avataaar/Circle Created with python_avatars Alec Kristi says:

    My biggest zap was when I was about 5 or 6 years old… A crew working on the main transformer powering our part of the town and a lumber yard went to lunch leaving the doors open. I was curious, climbed up on to the concrete pylons that the transformer was sitting on (about 8' up or so), and got inside. Apparently, at some point the power got switched on, completely unsupervised, and a bit later I ended up making contact with the bus bars on the 6kv side. I regained consciousness several hours later on top of the heap of trash next to the transformer, with a couple of small but nasty burns on my wrists, with veins exposed, and was shivering for the rest of that day, and could not speak for several days after. One of the burn marks on my left wrist is still visible a bit… Since then I have never had a major shock, just very minor zaps here and there…

    I'm one of those people who've received multiple shocks (some of them my fault, some not) but I'm under no illusion that I'm immune to them.

    I'd advise everyone watch those "unpleasant" videos. Being a "sensitive soul" is no excuse- everyone needs to know the consequences of a moment of carelessness lest they be the star of the next such video.

  8. Avataaar/Circle Created with python_avatars gizmo says:

    I've been hit by everything from DC to light, and 12v to 120KV. Worst shock I ever got (pain-wise) was from 12v. I was working on a computer monitor with a sheet metal frame and had my left hand touching the metal frame. I was poking around in the low voltage circuit (shouldn't be anything there that can hurt me, right? It's only 12v!), had a strand of wire from the 12v supply poke through my skin, lit me up like a christmas tree. The OCP triggered and shut down. My shoulders hurt for two days.

    Next worst was when I was working on a 220v live circuit which I thought was dead. I was working under a metal cabinet, so I had my left hand on the cabinet as I was poking in the junction box. I saw a blue spark jump from a wire to my finger just as I touched the bare wire. Fortunately I was squatting at the time, and when the current hit me it made me stand up, breaking the circuit. I guess I had a lungful of air when it happened, because I actually did yell briefly, however I did it through clenched teeth. Bit completely through my tongue on both sides. Other than my tongue, I didn't experience much pain. I was only in contact for about 60mS (7 pulses; I know because I distinctly counted very pulse that hit me; funny how the brain works in moments like that).

    Every time I've been zapped, it was because I was being stupid. Fortunately, I've survived long enough to be a LOT less stupid these days.

    Some bozo had hooked up the cooktop in my last place wrong, so the chassis was live. I noticed it wasn't working right and called in a trusted electrician who concluded the wires changed colour somewhere along the run and the previous guy had hooked the stove up by colour at the distibution box. Fortunately there were no ground points within easy reach of the cooktop and the floor was wooden so I never got shocked. Had my guy rewire it and all was well.

  10. Avataaar/Circle Created with python_avatars Alexander Borsi says:

    The human jaw has enough muscle power to cleanly bite off a human finger, but also the tongue which has no bones in it and is pure muscle… The only thing keeping anyone from doing either of those things, is the feedback from your finger/tongue saying "OW OW!" and your brain literally forces your jaw to release muscle pressure. If you are like me, and you have to try it once you learned this, you might notice that your first bite is pretty strong, and then it gets really weak afterwards. That is the feedback loop kicking in. Your body is not digital, it is much more analog and it has a bit of hysteresis in it. If you continue to bite, you will be able to override that feedback to a point, and you will get some more pressure in your bite. At some point, however, you absolutely will stop biting your finger due to either pain (another feedback loop that is MUCH slower, fyi) and/or the taste of your own blood in your mouth. (I highly suggest you do not bite yourself at all, but if you absolutely have to, please be nice to yourself and don't bite too hard… even to prove me wrong.)

    Imagine if that feedback was turned off. Zero feedback. It would be like chomping through a sizable carrot, or a thick cut of meat. Your body is much, much stronger than most people think it is. Don't be a statistic. Your best safety equipment is between your ears, and right behind your eyeballs.

    Step potential is facinating, this is where there is a fallen power line on the ground, the voltage dimishes in a series of concentric circles and a person standing nearby is safe – unless they take one step and the potential difference can be say 5000 volts and travel from one leg to another. Animals have no option because the PD travels from one pair of legs to the other. Safe thing is to stay where you are or shuffle away in little steps.

    Yeah, I'm gonna reference me dad again. He told me the gloves and dry surrounds thing long long ago. As the industrial first aider at the factory he'd seen some bad things. I'm glad he didn't mind talking about them unlike his army time in the early 50s.

    Thanks Clive, always a good thing to get a reminder how quickly things can go pear shaped

    I've worked on low-voltage switching power supplies for a good part of my life. I have always been so wary of high voltage that I refuse to this day to work on an mains-based switcher. I might visually inspect such a switcher with the power cable disconnected, but beyond that, I do not venture near those suckers. Call me a coward, but I am still alive all these years later.

    This is a must watch video for those who like to tinker with electricity. I used to do that when I was a teen. I was either brave or very stupid. I got zapped one time when I was 14 and I stopped then and there. Luckly it was only a 110V/60HZ tingle but I still remember that feeling 34+ years later. And Ohhh noooo! Big Clive wears, Crocs????????

  15. Avataaar/Circle Created with python_avatars Jef Damen says:

    I've touched mains in a pinching manner and it was really hard to get my hand off it, but since it goes to 0 volts 50 times a second, i was able to pull off my arm. From the wire, not my body lol.
    I think i was about 10 years. Lesson learned.

    If u're gonna test live wires with your hand, use the outside of your hand.

    U can really feel the 50hz vibration shaking your atoms.

    As a Hybrid Automotive Tech, I absolutely 150% agree with this video. Every class you go to starts with “Not only CAN you get shocked very easily, you can DIE very easily”. 300+ volts of DC voltage from a traction battery literally designed to flow AMPS of current to electric motors should not be messed with by ANYONE but a licensed person with the proper equipment and know-how to safely disarm and disconnect traction batteries. Check your gloves. Check your self. Check your environment. And for the love of god, do not do it alone.
