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

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.

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.

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.
@millomweb4 жыл бұрын
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.

@@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.

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.
