- Derek in part 2 of the item g 11 unsafe situations quiz gives us more unsafe situations that engineers and trainees can classify as ID, AR OR NCS along with do we need to riddor.

Helpfull ta
Brilliant thank really good mate
Interesting about bonding 18th edition amendment 2 dose not required bonding on incoming services to the building if they are plastic. However if no bonding on water mains any current leakage under ground could travel through water also so if no bonding current could be present on boiler body before travel through earthing from a spur but if you disconnected power supply and bonding the appliance body becomes live.
Also there is a major issue where problem was found the nutreal on electricity supply become faulty the current found way through earthing path. So there was gas explosions cause by that and they found fault where on gas pipe 35A has been recorded .

No Bonding
Is that nor ID and riddor then
@@tomkatgastraining no Earth bonding i would make a note on the cert, advise the customer to get a qualified electrician to get it done for them
@@BrothersGrim2012 don’t you mean leave a bonding notice at the gas meter to advise the responsible person earth bonding could be required
@@tomkatgastraining I’m only learning so far so just had a go without looking in book, if I’d of referred to book then I would of have a fuller answer
@@BrothersGrim2012 a lot more training required joe but keep it up 👍🏻
the requirement of the equpotential bonding is clearly on the out let pipe from the meter , so I think it should be there to protect what ever inside the property regardless the inlet pipe or before the meter installation . if not there I think it should classify as AR and Not RIDDOR
Thanks, very good teaching
Ever since PME (protective multiple earthing or TNC-S) was utilised in the 80's, the risk of elevated voltages on different exposed conductive parts has increased. It is for this reason equipotential bonding is necessary. Neutral and Earth a marshalled together at the meter position (as well as the substation) and therefore the installation earth potential (that being the same as the neutral ) can be a number of volts different to true earth potential.
Strange IET electrical regulations state that if there aren't any extraneous conductive parts on the incoming mains and the incoming underground pipe is of non conductive material then no equpotential bonding is required. However according to BS 7671 regulations differ stating PEB must be fitted within 600 mm and before the first T branch in pipework. I can't understand why regulations differ through both industries. I'm completely for the installation of PEB however other electricians would argue that IET regs differ 🤷♂️.
If on the Ecv there's a red ring present this indicates no PEB required. If there's no red ring downstream of the ECV then install a PEB clamp. It should be just below the ECV in any case.

Hi Derek
Great videos. Would you be able to do more videos on Unsafe Situations and how to best classify them. Are there any techniques to better identify them or is it just literally a case of keep practicing and revising? I did well in this video but struggled on part 1. Any help would be great on how to best revise. Thanks for all your other video as they've helped loads.
15 Min into vid the gas meter has open end and you've classed it as ar and not Id 😮... the medium pressure one ..
The question was about medium pressure inside a property not about an open end on a gas pipe. I said at the beginning of this section it represents not this is what you find so a medium pressure meter inside a property is AR. For your information there is a disk in the meter outlet also so still no open end.
Great videos,thanks Derek , a big help with up and coming ACS 👍
Hi Derek great videos, Can you make more videos like this as it does help. I got a questions does fly screen on a vent does that reduce air so you need a bigger vent or no? thanks
No you can’t use a vent with a fly screen because it can get blocked by insects and spiders webs.
The meter had a open uncapped pipe, so I marked it as ID
The question was about the meter being inside the property not the open end 😜
Excellent very helpful mate...been a Gas engineer for over 35 years...your ironing out these grey areas.

Excellent video Derek on these unsafe situations. Its good to know what you will come across on jobs onsite. Thanks.👌👍👍😁😀
I meant socket!

Fantastic video Derek, highly appreciated the best videos out there for unsafe situations are your videos part 1 and 2.
Hopefully part 3 soon 😋

GSIUR REG 7(1), PIPEWORK SUITABLE FOR GAS BEING USED IN AN INAPPROPRIATE LOCATION, would that include being less the 25mm from light switch?
Really enjoying these videos 👍 keep them coming!
Fantastic, Thank you, I love this questions and answer with explanations! Well done !
Hi Derek just like to say a big thank you for all your time that you do it is a big help. Thank you
Great video, very informative. Thank you👍👍👍
Excellent, thanks. ACS due next year so this is all good prep. 👍🏻
Well done Derek , Keep them coming . It brings me up to speed!🤪
Thank you Derek , Mohamed Hassan
Thank you, Nikola Ditsov
Brilliant, really informative , please keep them coming🙏
8 00 phone gas board 🤣🤣got one wrong derek cheers 👍
👍 Always something to learn from the Guru 😎
Brilliant video. I did better in this one than I did in part 1 😎. At 14:15 when talking about the flueless space heater and how it should be at least 1 metre away from a vent, how about a door? I saw this type of flueless space heater installed in a hallway not to far away from the main door to the house. What are the requirements for that? Thanks Derek. Much appreciated 👍🏻
Asian Jon. Training.
The door is not that much of a problem because it’s closed most of the time and it’s a big area. The ventilation being too close is a problem because it could stop the ASD shutting down and make the room vitiated.
Brilliant keep them coming 👏👍🏾
so paint on a flue or boiler is AR?
Brilliant video. Thanks alot mate
Great stuff, keep them coming.
Your are the best 🌹👍👌✌️
Another fantastic Video

Medium pressure gas meter has an open end on outlet 🤔 is that no ID? 🤔
The scenario was the medium pressure meter was installed inside not the open end that’s why I gave scenarios not just said what’s wrong but yes an open end is ID
CH👍
Great video again Derek, brilliant for revision. Would you mind being the first person to actually demonstrate / show the procedure of unsafe situations practically. Ie actually disconnecting appliance, capping off meter, etc. Thanks 🙏
