Thanks JW these videos really help people who can’t ask the questions for fear of being roasted by their peers.
Putting tape over " a load of old crap" LOL you have a way with words and amazing dead pan delivery style. . My main job is designing industrial lockout solutions based on safety PLCs and trapped key interlocking systems. I work a lot in the rail industry controlling access to 750dc third rail and OLE 25KV on the railway. The biggest problem I face is not the lockout system but trying to ensure they are taceable and stop people from defeating them. It amazes the lengths people will go to avoid locking out, they would rather work unsafely and risk their lifes then take a few moments to lock something out. You honestly would not believe the things I have seen. Well done on the subscribers John well deserved. I aspire for my first 1000. Another fantastic video John thanks for sharing. Regards Chris
Go on, tell us then!
marcaxe My latest one is someone climbing over a safety fence at high level to get on a train roof. The train was energised with a 25Kv overhead line at the time.
Love the way JW tells you straight. Don't think this video really needed as lock out is self explanatory, but his videos are a great help keeping up to date for an old codger like me.
Nice to see you hit 100k JW. That's another channel managing the magic number that I've subscribed to for quite a while - Fran Blanche got there recently and I think Big Clive hit 500K a while ago. I suspect much overlap in these subscribers, proof there's room for lots of excellent channels like these.
Ahh, the red Master Lock plastic body 'lock out/tag out' lock, that they put the most secure core in out of any of their locks. I really wish Master would put that core in some of their other locks instead of the junk they use.
Haha, that's right, you must be a lockpickinglawyer fan :)
The irony here is that Master Lock knows they can't have the lock core be the weakest link. If the lock is physically broken it shows proof that someone may have done something bad (there are times at least here in the US where breaking a lock is legal). A picked lock does not show proof of tampering.
@@Petertronic I was going to make the same comment Christopher did and for the same reason.
It's also the crappiest lock body of any of the Master locks. A piece of piss to brute force. But in this case that isn't a problem. Maybe even an advantage.
@@bdf2718 Definately want to be able to remove the lock if the key goes missing.
Also definately do not want to be the one who gets the bollocking for losing the key and generating paperwork to demonstrate that the lockout was not bypassed improperly.
@@rarrawer Also, you want it obvious when the lock was removed improperly. So it's hard to pick/bypass, easy to break. If it were easy to pick/bypass, some idiot could remove it, get somebody else killed, put the lock back and make it unclear what happened. When you can see shattered bits of lock body, there's no hiding what happened.
Also, having to break a lock is more of a deterrent to an idiot than a lock you can open with a bit of bent wire (some Master padlocks can be opened that way).
I use the Martindale lockout kits, very nice!
Omg John beats on the 100k subscribers
Proudly one of your 100,000 subscribers..Congratualtions. Before we were onsite at a sawmill, I had no idea about lockout/tagout...you do NOT want the stump chopper grinder becoming live..
Congratulations for 100k subscribers.
The problem with your red tape lock out kit was that you didn't illegibly write 'DON'T TURN ON' in sharpie pen on it.
@@mikeZL3XD7029 He was making a joke, likely based on seeing this very thing.
@WhiteShadow2k1 I was replying to someone else, that just didn't get what was being said. That individual has since deleted their post.
It's nice to see more videos from you.
Another top video JW. You missed out the MK 3 pole fan isolator lock outs... 😉 The first ones I ever had in the late 80's, red plastic, like a scissor action that also fitted into 2 holes either side of the isolator switch. Also came with a MK padlock.
Your Connector Roulette video made me subscribe. Well done on that video John!
Those coloured padlocks I have one and it made of nylon /carbon composit even the shackle so it fully insulated, silly idea as you could cut the shackle with a pair of cropper’s . My other locks are all metal with hardened shackles. As for working live it isn’t illegal as we have to work live sometimes such as Ze and Zs as well as taking voltage measurement’s and faise rotation . Fantastic video John as always 👍❤️
Nice job
We live this everyday along with confined entry permits and hot work permits inside larger mixing machines
Failure to follow procedures along with the danger of a fatality is also instant job loss
First Time I have seen an electrician on TH-cam using a lock off kit.... :)
Nagy did last week I'm sure
How about a Post-It Note: "Don't touch" ?
Works for me!
@@andljoy I've actually seen it. Crazy!!
Me too 😲
How about "Don't even think about it"?
577 VAC / 60 Hz in Canada.... well at least for industrial circuits.
I think sometimes it is necessary to work on live circuits, but only:
1. In locations where you simply can't switch off the electricity, for example in a hospital.
2. Use additional safety equipment, for example a rubber mat to stand on and gloves which are rated as insulated.
3. Use fully insulated tools, instead of the standard partially insulated ones.
4. Your experienced.
And in Germany we got the five safety rules of electrical work according to VDE 0105:
1. Isolate the circuit.
2. Prevent reconnection.
3. Proof if the circuit is really dead with a tested voltage tester (two pole!), and test all-pole!
4. Earth and short-out all line conductors (only of interest for voltages above 1000V or bare overhead lines).
5. Cover and shield any adjacent live parts/components nearby the working area (in most cases irrelevant too, that's for example when working in a transformer station).
Tested voltage tester means, tested on a known circuit or with a special tester (available by some manufacturers like Megger or Fluke), before AND after you proof if the circuit is dead. To short-out the lines on voltages above 1000V is a pure safety thing, inductive or capacitive coupled in voltages in such high voltage ranges can deliever enough current to kill a person. Otherwise than it is in a low voltage area, where you don't notice this, and can measure it with a high resistive multimeter only.
No arc flash protection required for live work in Germany? I'm surprised.
@@coffeecoffee5914 Yes, it's required in most cases. Look at point 2, I mentioned additional safety equipment. In final circuits, which are in most cases fused with a B16 A MCB, I think this doesn't make any sense. In that case they want you to wear face protection and flame resistant clothes (pure cotton for example). If you work on a circuit fused with 3x63A or more (three phase is common here, even in residentials. 3x63A is standard in the service entrance of a single family house), you'll have to wear special arc fault resistant clothing.
Great job!
Industrial three phase panels are the best for locks. I always like the old MEM boards where a large pad lock could be used to lock off a circuit. Alas long gone.
I spent some time as an electrician in a south African coal mine. I locked out a machine as the operator kept driving it through deep water dragging the D.C. traction motors through the puddle. The mine engineer came to me whining that the motors were flameproof so therefore it wasn't a problem. I told him to fuck off and educate himself and come back to me when he'd got the water pumped out. Five minutes later I saw the machine drive past me. I stopped it and asked the operator why the machine wasn't locked off. He said "Mine Boss cut off lock" I walked out off the section using every lock out i had, I had several, to lock out the conveyor system. Effectively stopping the section from producing coal. I jumped in a Jeep, drove to the surface and reported this to the mine manager the same time tendering my resignation as I no longer wanted to work with these cowboys.
Even an efficient lock out system is fallible! Watch yourselves out there.
Excellent, thanks.
Most of our circuitbreaker boxes in the Netherlands are built in a closet, which can be locked. Easy peasy.
Here in rip off Britain we think of many new inventions which over complicate things, ensuring you buy specialist tools to carry out a single given task.
100K congrats and a safety video to celebrate. We don't have that system since the switches are closed in a keyed door ment to be open by the responsible technician
Not reliable if you have a bunch of people working on different circuits at the same time.
If I was a sparkie and was offered that, I either would refuse to work on the job or lock the main switch off.
@@millomweb Yes that's why also congrat also the video itself as extra measure precautions. Don't know if exists here such lock tag devices at stores. Normally here it is one person that goes to work but when more they rely on the key of the boss of first to arrive on the work.
@@MalagasOnFire Could be done like that but not as good. It also should involve signed documentation too.
@@millomweb
Found something which require the holes on the Switch:
profor.pt/produto/cadeado-disjuntor/
For example here in sweden, we don't usually use lockout/tagout. Instead, isolation switches have a special warning label (should have) that says they are NOT to be used to shut down equipment. The reason isolation switches DO have these warning labels, is because only the person who turned the switch off, should turn it on again. You can turn on a switch someone else have turned off, but ONLY after 100% verified that its safe to do so.
The reason isolation switches shouldn't be used for this, is because imagine someone using a isolation switch to shut down a factory machine at friday, and then start up factory again at monday. Thats incorrect use, because if someone would be to work on the machine during the monday before factory opens, the guy starting up could kill the guy working on machine.
If you want a switch that is to be used to regularly shut off things for other causes than safety, , then wire TWO isolation switches in SERIES. Put warning label on one of them (or if they both have warning label affixed from factory, remove one of the labels).
Then people know that if the switch without label has been turned off, its safe to turn on again. If the switch WITH label has been turned off - DONT TOUCH. But its important to clearly label the switches "SAFETY SWITCH" and "REGULAR SHUTOFF SWITCH" so people clearly know not to touch safety switch.
For circuit breakers, the easiest way to "tagout" a breaker in sweden, is to just put electrical tape across it. The best tape to use is green/yellow earthing tape. Just tape it from the top, over the flipper, to the bottom. This clearly tells "Do not touch".
Theres only one exception when lockout is used, and that is in public accesible spaces. In those cases lockouts are of course used, because any civilian could otherwise touch the breaker and cause a accident. An example would be a isolation switch located in the customer area of a shop.
But if the space is closed in such a way only authorized people visit that space, everyone should know that a turned off isolation switch is turned off for a reason, DONT TOUCH, or if a circuit breaker is taped off - DONT TOUCH.
In sweden, if you turn on a isolation switch that someone else turned off and cause an accident, or if you turn on a circuit breaker that have been taped off by removing the tape and turning it on, and this causes an accident, you COULD be liable for causing bodily harm.
Some isolators come with holes so they can be padlocked in the off position. I've come across locked switches like this where the control and padlock is fitted to the hinged front of the casing but the lock doesn't lock the casing shut - so simply open the casing and turn the switch on with an adjustable spanner or such.
Well it sounds like Sweden at least has common sense in their electrical regulations something I can't quite understand where's my dictionary I have to look up this word "common sense"?
Do you also put green/yellow tape over your ignition switch keys ;)
@@millomweb No, the difference is that a breaker in a trusted location, then you don't need to lock it out. In many places the breaker panel already have a lock (then access is already restricted to those few that has the key), and if not, the breaker panel is usually located in a location inaccessible from the general public.
When a breaker panel is located in such a way its accesible to the public - for example in the customer area of a shop, then it should be locked out during work. You do NOT need to use a personal lock. Its enough that a cashier or shop manager affixes a lock that the cashier or shop manager has the key to, and when you are done, the cashier or shop manager removes the lock. (usually the lock is affixed to the door itself, not just the breaker affected). If the breaker panel door already has a lock, then cashier opens it for you, then you turn off the breaker, and then the cashier closes it for you. Then you can trust no customer is gonna touch the breaker since the door is locked with a key only casher/shop manager has.
If multiple people have the key to the padlock or breaker panel door, and you can't inform everyone about the lockout - just put some tape over the keyhole, like yellow/green tape. And if possible, just a paper letter saying "DONT TOUCH". Then everyone knows that work is in progress.
@@sebastiannielsen We put notices on in any case but still don't trust that - hence the use of locks.
And if I didn't trust even that, I'd enforce safety by connecting the live and neutral wires near where I was working - then if someone did override normal safety systems, another would protect me - even if that meant tripping the whole supply to the premises.
Hi John please could you provide some Links to source the various types of kits? Many Thx.
I am sure that many of my compatriots are aware of a situation where an operator has ripped off a tag...along with the isolator ring leaving an open box with exposed live terminals.
No he wasn't sacked. One has to wonder about the committment of British companies to HS and the IEE regs.
@@mikeZL3XD7029 Not specifically but yes, if there's no other reason, reckless endangerment would be an appropriate charge
@@mikeZL3XD7029 Are you the same mike trump from ECN? if so, I missed you. I'm the same chipmunk from there. (sad to see how derelict the site is, at least the non US forum)
Hi, can you purchase a lock kit for the main switch? The red one on the right, I’m wanting to completely isolate the unit.
"Bear in mind it's your life being put at risk there, not anybody else's." I thought that's what apprentices were for.
@@mikeZL3XD7029 I've never trained an apprentice for long. I keep having to replace them.
@@mikeZL3XD7029 _whooooooooosh_
The small aluminium ones with the screw feel the best to me , small easy to carry and work on everything.
What is the significance of the different colors of the clades?
Unlikely that they will reduce nuisance tripping if fitted upside down in the on position. 🤠
I used d to repair photo copiers large central ones and would have one in bits all over the floor and people would come up and place a piece of paper on top and say I only want one copy. How they expected to get a copy when it is in bits I never understood. With out lock outs people will just switch things back on. They must not be inconvenienced.
Is there a risk that the padlock could block the adjacent MCB/RCD/RCBO from tripping? The shackle seemed to be blocking the next MCB.
you cannot stop an mcb from tripping by blocking the lever, even if the lever is held up and a fault occurs it will still trip.
Hi, does anyone know what size screw wylex use for their consumer unit lids. I've got a sheared screw on a new metal unit?
M5x10 pozi if anyone cares
I'm a BIG fan of lock out kit. I preach about it all the time, and I have a large selection! Don't like your plastic hasp thou, always metal!! Fyi the multi fit ones you show, made by kasp ect are the best, but master lock have a good version of it also.. I do not get along with tiny stupid metal ones that need a tiny screwdriver!! I keep asking Reece safety and masterlock to make a kit, with a multifit, tag and padlock for under £10. That way everyone, even the cheap skates will lock out!!! So many people, especially domestic, don't lock out at all, and have never heard of it! The more it can be advertised and talked about the better!! Thanks for the video!
I prefer metal also but the company I work for only supplies plastic equipment including plastic locks with a plastic HASP! If you just give the lock even a stern look it breaks. Not much better than tape as an actual deterrent.
How are you celebrating 100k btw?
Perhaps first hand experience of 400 volts would act as a deterrent.
Not enough for the tree cutters / I think it was actually the power company down my way, although they did leave within a very quick hurry that day. then they started sending me nasty letters about cutting trees on lines it's sad when you're more professional than the professional. I was not home for 1 hour and my neighbor was so annoyed that they were like we should have just had you do it, I left for my dentist appointment as they got there and when I came back they were gone and so was the power and all the electric heat in the neighborhood and water for a whole day + night with elderly Neighbors...... NOT GOOD !!! But hey at least it was the power company that let out the White Lightning.
100k special?
Wait, UK sparkies need to buy their own LOTO tags out of pocket?! Over here in the US OSHA regulations require their employers to furnish all necessary safety equipment INCLUDING LOTO equipment.
I guess it ought to come under PPE ! Lots of UK sparkies are the employer ! Or maybe then the customer is the employer !
If you work for yourself you have to buy them and some don't
@@RobertSzasz and they'd be in violation of OSHA regulations. Surprised they stay in business very long doing that.
@@TestECull working on residences. Self employed? Who's going to call the regulators? It's a stupid thing to do, but lots and lots of people cut safety corners
@@RobertSzasz Working on residential systems is probably the worst place to be lazy on LOTO to boot. Homeowners tend to be pretty damn forgetful at times and are far more likely to randomly flip an 'off' breaker back to 'on' if they see one...
I'm not particularly concerned about safety but even I'd make sure to thoroughly LOTO the breakers if I was a pro sparky working in someone's home.
I bet the lockpickinglawyer could pick those lol
Why on Earth can’t they standardise small breakers so that one device fits all of them and you don’t need to carry a whole bag of different ones around with you?
What are the large square keys used to control access to high-Voltage equipment? The keys are about 30 mm square and fit over a square part in the lock. This square part carries identifying letters or numbers, and each key will only fit where it is supposed to. The same key is used both to switch off the supply, and to gain access to the equipment enclosure. To gain access you need the key to unlock the door, and you cannot remove the key from the switchgear to use it in the door lock without switching off first. I’ve seen these used in a high-Voltage experiment in the film ‘On the SAFE Side’ which was shown as a BBC Trade Test Colour Film in the late ‘60s, and also for the million Volt Marx generator which used to be at the Science Museum in London until they removed almost everything interesting from display.
It could be done, but won't be - consumer units are type approved, and to have devices from mixed manufacturers would require approval testing with every possible combination of devices in there which would be ridiculously expensive.
Not a fan of BG then.......nice vid well done on 100k
Sparkles are quite reluctant on the uptake of this process, fitters and the like are even worse with steam, compressed air hthw etc. why is the person issuing the permit seen as being weary due to the tradesmans ignorance
I see one problem, you going to lose the key because you can't put them on your keychain unless you want to have your key chain dangling the locks as well. I don't know about you but between the car key fob and the giant cell phone ( I didn't want and I was forcibly upgraded to without a headphone jack ) I'm having an issue with my pants staying up even with a belt!
I prescribe braces!
Where are u from
This guy sounds like he would be a load of fun at a party!
'A load of old gubbins.." lol..."
I would use my screw driver to take the cover off and remove the conductor(s) from the device....and also put the lock on...
I found my Elderly Dad changing a light switch to live wires without turning off the breaker 😥I started screaming at him, he just said.. it is ok, the switch is off.
my eyes are twitching now because of stress...
Take me through the padlock colours again please I don't think I got it first time!
They are colored per phase you no black grey red yellow orange purple white green green yellow, color coding sarcasm
Lol meanwhile in the Wild West of Canada we work on live electricity at like 15/20% of the time and usually without insulated tools. In fairness it’s only 120v hahahaha
That can still kill you. Although I’ve accidentally been shocked by 110V AC and lived to tell the tale... But then, I’ve also been shocked by 240V ‘cus although the item I thought I isolated appeared to be dead. The control circuit for the contactor relay was fed via the lighting MCB and was still live 😡
@@Mark1024MAK Indeed. I've worked on both sides of the atlantic pond. And there are times when 240 just tickles, and 120 grabs you. There's bravery and there's stupidity.
I once came across a situation where the contactor coil was fed from a completely different building and different substation than what it was controlling (light columns on a university campus).... I've often wondered about the potential (heh) voltage differences that may have been present.
In fairness, it was flagged and had a local isolation switch for the coil feed... that disappeared into a conduit headed
Mike Trump yeah all of those are higher voltages then 120. Anything higher then 120 we don’t work on live.
PPE helps.... common sense, while rare, also helps. But be aware... working live at any voltage that can hurt or kill you is not to be sniffed at. Stay safe man
I do 240 domestic stuff in the UK, but that can still kill you easily. Familiarity
breeds contempt
JW + BG = 🙈

ENGAGE SAFTEY SQUINTS!
@@coffeecoffee5914 safety Squints do work I usually use them when I'm tired of getting stuff stuck in my eye because I'm wearing the safety glasses, I have now learned that some materials are better with safety glasses like cutting wood and some materials are definitely not safe to use with safety glasses.
Out of interest, do you find this to be an issue in domestic properties? You'd think not, what with you being the only one working there, and being able to tell people not to turn it on, but there'd probably always be some numpty who'd want their cell phone charging or their kettle boiling.
Just connect the user across the main supply fuse, that will stop any pesky phone charging.
Other trades on domestic cause issues
I knew you were working on it but I didn't think *that* was anything to do with it. Does it hurt?
Or just wip the cover off and remove the relevant phase and neutral conductor and replace the cover
That is safer than any lockout kit
1st pleeeeeaaase
What actually is ............''a pile of gubbins''.......... JW ???
Alternatively, simply remove the breaker.
>
Tried it...serious frowns ensued. 🤔
And what would you do with the flapping wires?
And how is this any quicker?
If the scope of the work allows access to the insides of the board easily, put the live wires (PHASE and Neutral) into the earth bar and be done with it.
@@TheChipmunk2008 I never suggested it was any quicker nor did I imply it was better.
It's just what we used to do in the old days before these fancy lock-out mechanisms were devised.
In the seventies it was mainly fuses, so all you needed to do was pull out the fuse and keep it in your pocket.
When the first breakers appeared you could also just pull them out and keep them in your pocket because they were compatible with the rewirable fuses.
Next came the breakers on the DIN rail. This is when it became a pain because you then had to physically remove the breaker.
These lockout devices are a great invention.
>
The Electricity at work regs 1989 forbid you to open the consumer unit without the main switch off-therefor at some point you would need to cut the power to the other circuits-in a commercial /industrial setting this is often not practical and the thought of workers downing tools whilst the sparks sets about dismantling the fuse box would severely ruin the foremans day.
By using these lock-out gizzmo's,only the circuit to be worked on is de-energised.
