LPG domestic tank earthing.

[fredrico]

Does an LPG tank serving a domestic property need earthing ? I was planning just to put a main earth bond onto pipe where it comes into property. But does the tank itself need earthing to prevent static electricity ?? Cheers.

no such thing as an `earth bond`...unless your a pat tester that is...lol
bond it within (ideally) 600mm of where the pipework enters the property....

Yes, an LPG bulk storage tank should have it's own earth. LPG storage is a completely separate area of expertise with it's own set of regs. You shouldn't undertake any work on an LPG installation unless you're familiar with those regs and you must have a copy of those regs plus you must be insured to undertake LPG storage work.

I did not know that cheers, does that include wiring the oil boilers

i stand corrected marvo then.
Thanks.

What happens when the property is being rewired, and the tank is already there ?? Can i not just put an earth on the pipe where it enters the property , or am i not insured to do that ???????????????

 

[Marvo]

If the storage tank is not on the property then you shouldn't need to go anywhere near it but your first question was whether the LPG tank needed earthing.......I'm suspecting I'm not understanding your question. When you say property are you meaning on the grounds or just in the house? Also when you say tank do you mean bulk storage that's refilled by a truck or do you mean a bottle you throw in your boot and exchange for a full one at the local hardware or garage?


The only thing you should need to do is the usual crossbonding of the services at the CU.

The older I get the more I forget what I thought I knew....................

I'm coming back as a plumber ffs.

 

[stuartcourt]

only tank not boiler needs alternate regs then?

 

[Marvo]

I'm confused by the original question. I think my grasp of the English terminology is the problem, I'm not sure if the OP is talking about a bulk storage tank installation



or a refillable bottle

 

[fredrico]

The tank is in the garden of the house, it gets refilled by a truck. The lpg tank is about 5 metres away from the house. I thought i could just put a main earth bond onto the pipe that feeds the house. Thanks for your advice Marvo.

Yes Marvo a bulk storage tank.

LPG bulk storage tanks always need earthing, and will have a factory provided earthing point incorporated, generally on the welded support structure. Static is a very real issue with LPG, especially at times of tanker truck re-filling of the storage tank(s). In such cases the tankers will normally be provided with a 30m retractable 10 or 16mm cable on a cable earth reel, the cable being attached to the storage tank for equalisation purposes prior to any pipe connection between tanker and storage tank and filling operation.

It has been a few years now,but i remember that the "earth spool" had the slip rings disconnected from the truck until after the other end was clipped on the tank super-structure. Bought a Leyland Mastiff that had the earthing procedure etched on a big mica sign fixed to chassis,happy days...

Re the OP original question which I read as asking if it requires bonding on the pipe where it enters the property not the Tank.

Any external services coming into the property need a bond cable of the correct size connected back to the CU earth bar, this includes LPG pipes if it is a metallic pipe.

Yeah..

Cool, thanks for clearing that up.

The bulk storage tank should ideally be earthed via a roded earth electrode!!

 

[ackbarthestar]

I think you need specific training to touch this stuff, that means registration and that the fire brigade need know who you are.....

It needs MPB inside the house
It needs a separate Earth Electrode
It needs an earthing point, usually a brass stud for the tanker to make an electrical connection to disperse static.
It does not need a PME export (you must decide what is the best route here)

This liquid gas is lethal, if it leaks it lays on the floor, its flash point percentage changes unlike natural gas and when it goes, it chases you around like Australian green crabs.
So beware and have the appropriate insurance. You have been warned !

10mm bond where comes into house mate,I lived out in the sticks for 10 yrs, same thing in my house... Job done..

 

[Engineer54]

So because that's all you did, that's the way to go is it??

Yep, that about sums it up!! lol!!

The earthing point on the bulk storage tank will normally be provided by the tank manufacturer, as will the safety earth connection point.

 

[fredrico]

I aint touching the tank. I got a bit carried away on my first post. I am will bond gas pipe when it comes into the house. You ladies make me laugh.

 

[fredrico]

Thanks for your replies.

Earth it as a NG installation and treat it like no other, at the end of the day its introducing an earth potential and so requires bonding. No need to contact the fire brigrade, possess special insurance, ACOPS, earth electrode, etc just to bond it. If there is no meter, then clamp it on the consumer side of the OPSO/UPSO regulator.
