Gas safety taken too lightly

[Searush]

How about electricians tape and indelible ink?
While on the subject of gas safety no one has yet mentioned the importance of using safety matches when checking for leaks! (Boom Boom!)

I've done that - it works well, provided you've only just connected the supply.

...................not forgetting of course that the box of matches must have 'Marine Use Only' on it. Ordinary safety matches wont work at sea.

I forgot to mention. Do not on any account use a smoke match. It will only set off your smoke alarm. That's the one next to the gas alarm which is next to the CO2 alarm.........

CO2 alarm. thats impressive. Twice as good as a simple CO alarm ?

Electricians can get it... used to identify the yellow phase on three phase systems.
Now someone will come along and tell me they have changed the colours on three phase systems !

Er...Yes, they have - 3 phase used to be yellow, blue and red for the 3 live phases, with black as neutral. However, since 2004, the three live phases have been black, grey and brown, with blue for neutral. Earth remains unchanged, as green/yellow stripes.
These colours are for the UK and Europe, other countries (like the USA) are different.

Why o why can't they leave things be ?

 

[greenalien]

Well, obviously, it's much easier to tell black, grey and brown apart, (especially when wiring something up in a cramped space with poor lighting!!) compared with red, yellow and blue...isn't it?!!!

No I wont. Dont understand Irony.

Sorry, I hope I didn't offend, just wanted to make it clear that I was not endorsing the handy work done.

Incidentally, can anyone tell me how the bubble leak testers function?

Even better, I believe the same standard allows an alternative of all three phases being grey, with sticky labels to identify them

I thought they had probably changed.
They had to change.
Too many Corgi gas fitters were electrocuted trying to connect gas appliances to the yellow phase

When you push the top down it diverts the gas flow through a glycerine type fluid, which is in a small perspex container at the bottom of the tester
If it shows bubbles when you have no appliance on, or taps open, then you have a leak somewhere down line of it.

Running a new copper gas pipe.

As per my last thread regarding replacing copper tube.
Now I know things like washing up liquid must be rinsed off, after using to check for leaks on compression joints as it is damaging to copper.
In order to ease the feeding of the new pipe I intend to smear the first meter of it in vaseline, unless anyone tells me it may be damaging to copper.

Frankly I wouldn't bother. It's not like cable where cable starts to 'grip'.
Try it first without.

Glycol not glycerine. Latter would probably be too viscous when cold.

A vivid reminder to us all of what a gas leak can do.

This is what was left of the once beautiful motorsailer Maid of Jura a Colvic Watson Jura Class 34'-6" which blew up and sank in the Crinan Canal basin after a gas leak in 2000.

Even better whenthere has been a fault, followed by a fire, and you are trying to workout which is which and it is all covered in soot and the lights no longer work...

Here's a controlled gas explosion.....

What colour tape did they use?

A recent thread about gas safety spurred me on to install a bubble leak tester, mainly because the copper pipe, where visible looked tired. After installation it showed a leak in the system, in order to narrow it down, I checked the isolating gas tap beneath the cooker for leaks, all seemed good so I isolated the cooker. The tester was still showing a leak, so I checked the connection down side of the tester, all good.
Bugger! this meant the leak was in the copper tube which runs into the bowels of the boat. I decided to take the plunge and rip it out, this involved cutting a huge hole in the back cabin, removing the water pump from under the cooker well, and pulling the old pipe out with a mousing line attached. Not an easy job it took nearly 2 hours, but here is what I found.

Personally if I found the idiot who did that I would....!
