Asbestos

I'm having an argument with someone on Facebook about why 48431 hasn't been overhauled on the KWVR, and the reason he has given is because of asbestos lagging.

I pointed out that it's had two overhauls in preservation, one initially in the mid 70s when it returned to steam and a second one in about 1990. Surely any asbestos present would have been removed on the first overhaul and not put back, and certainly not on the second one?

anyone know?

 

Thanks Martin, I can't honestly see asbestos being used again, I used to work in an insurance office in the late 70s/early 80s where one of the clients was an asbestos manufacturer and at that time, it's use was being stopped and we got inundated with historic claims

 

Asbestos was still in use for many things well into the 80’s although it’s use as a lagging had essentially stopped. Brake linings was one major use, along with jointing materials. Not sure when asbestos cement cladding finished being made but I think it was in the 90’s. There was a derogation to use asbestos mud hole door joints on loco boilers until 2004.

 

Rochdale Electric Welding overhauled the 8f boiler, the chassis was done at Kirkby.

As a Worth Valley loco dept volunteer back in the late 80's early 90's glass fibre lagging was the norm for boiler lagging.

From what i recall the 8f requires new tyres and other significant works which is probably why it hasn't been overhauled.

 

Yes I've heard that too

 

Genuine question: is there any risk of asbestos (in other than old brake blocks) in any part of a tender?

 

I was discussing 48431 with staff last time I visited a few weeks back... The 8F's fireboxes are both knackered, and apparently the rear loco dragbox is so wasted that "When it was coming to the end of its ticket, there was surprise that it didn't leave its tender and train behind"... Sounds like if it is considered for overhaul, it will be a very costly one.

Apart from a few with Ferodo linings (S&D 7F's IIRC) steam loco and tender brake blocks were normally solid cast iron. I think the previous reference was to car brake shoes. The only use of asbestos in the tender that I can think of is in the asbestos tape that was used to insulate the steam heat pipe.

I'm pretty sure that 45596's old tender tank has been put to one side for potential use with the 8f in the future.

42765 maybe ?

That and possibly gasket joints in pipework.

 

I'm pretty sure that 42765 never went to Kirkby, Bob. ISTR that the loco (only) went straight from Barry to the KWVR and the tender (ex 42756) from Steamport joined it there.
76079 was stripped down and rebuilt at Derek's works in Kirkby so maybe that was the boiler Martin saw? A young Ian Riley worked on it there. At least one of the ex Hungarian S160's was also in the yard there - I've got a photo somewhere.
Cheers,

My reference to brakes was a general one covering any sort of brake that involved a lining, not just car brakes. I had a lot of involvement with winding engine braking systems, most of which had Ferodo ZA1 linings (zinc asbestos) but there were many other uses for it, such as in clutches.
When did the use of asbestos in ironing boards and oven gloves stop?

 

42765 arrived at Bury in an almost complete state from Kirkby in the summer of 2003.

The tender for 42765 ran with 43924 on the KWVR in the 80's until its withdrawal in dec 87.

The Fowler tender that ran with 48431 is the one that came with 43924 from Barry and was under major repair during the final few year the 4f ran in the 80's

 

All asbestos was banned in the EU post 2000 but is still used in other places around the wall if there is any present on the boiler before any work could take place.

 

Something relevant to any 'repatriations' from places such as Indonesia, where locos have to be able to hold some small boiler pressure to prove they don't fall under the legal ban on exporting scrap metal.
