I wouldn't do that with the dust from my vacuum, which is largely my
skin. Or flour, or anything else for that matter. Even if it doesn't
carry a cancer risk it's pretty unpleasant.

Should have asked in the last post - can you provide that evidence
please? I would be interested to see it. Brown and blue asbestos were
banned for UK import in 1985 to my knowledge, with white being banned in
1999, under an EU-wide directive. Labour had promised to do it upon
election, but apparently Canadian opposition and lawsuits were too much
for any one country to take on.


Well I'm going to assume that you aren't asking for evidence of the lack
of man-carrying strength, so it must be the cancer risk

So.. a link or two...

http://content.nejm.org/cgi/content/full/338/22/1565

That's interesting as a Canadian study specifically stating that the (US
Government) EPA estimates for the risks are at least 10 times too high.

And there's a nice summary he

Sorry - only just managed to plonk myself in front of the PC. Was finishing
part of the garage conversion yesterday - spraying the walls with a
fire-retardant mix of asbestos. ;-) Oh - OK - painting it with Dulux
emulsion! Anyway - thanks for these links.

Haven't read them properly yet - though a brief look at the first one shows
me two things that I immediately find questionable:

- the study was limited to women, to eliminate workers in the asbestos
industry
- [JW] so it would likely also eliminate anyone doing DIY asbestos removal
too? Surely factors like DIY working with the stuff should be taken into
account in any environmental assessment, as that's day-to-day usage?

- The results of this study are reassuring with respect to lung cancer, but
there were significant excess numbers of deaths due to pleural cancer (seven
deaths) and asbestosis (two deaths). The instances of pleural cancer suggest
an excess risk of mesothelioma. However, since historical death certificates
reflect the incidence of mesothelioma poorly we have launched a separate
study based on a province-wide survey of hospital records.

On the second article, much of the summarising at the end simply sounds like
the "yes, we as the asbestos industry know that blue asbestos is really bad,
and so by getting rid of that, we have cleaned up the industry".

I haven't scoured each article properly, as I said, and so I haven't found
evidence of "_all_ types were banned is so that someone could make a quick
buck".

I haven't found evidence of white asbestos being a significant risk
outside some production facilities - and even then it looks as though
contamination with other types may be involved. Certainly smoking is
strongly linked.

I guess it depends whether you want to be precautionary safe and ban
everything that isn't proved safe, or ban only things that are proved
dangerous.

Links to papers showing a risk from _white_ asbestos _outside_

I fell through a flat asbestos roof as a boy. Ripped a nice gash in the back
of my thigh. As I was laying face down on the operating table having it repaired I kept complaining about a pain in my foot. Finally to shut me up the surgeon told me to roll over while he examined it, a small cut in the top of my foot. 'Thats only a small cut. Nothing to worry about " but to stop me whinging he put a few stitches in it. Stitched a piece of asbestos into it. For a few years I had a strange bump there and then it started to get sore. Back to the hospital. It had turned gangrenous. Had to have it cut out.

I suppose if that happened today solicitors and barristers would have a field day but in those days the concept of an 'accident' still existed

No chance. Not only is asbestos cement weak and brittle, but there is
the danger from asbestos fibres when it breaks, as it surely will with
any weight on it.
Instead, use a ladder or staging to get into a position where you can
remove the moss with a pressure washer. Otherwise, don't bother.

One of the worst things you can do with an asbestos roof is to
pressure wash it. Now that really does loosen the fibres up!
Personally I leave mine and its moss well alone. I fix it where it
needs it, otherwise we live in blissful mutual ignoring of each other.

No I used to regularly cut these sheets for lengths with a jig saw on a
black and decker drill, I'm still here. The dust seems not to be fibrous at
all, its just heavy and drops to the floor. However that stuff is
brittle,and although when it was here I have been on it, I did take great
care with weight distribution. With age though and building movement it
tends to crack and fall to bits. In the end I had to pay to get the two
buildings removed and they were of course careful, and all the h and s stuff
including the double bagging and marking. One needs to remember that
Asbestos is a naturally occurring mineral, its how we made it into various
shapes that has made it dangerous due to the concentration, so to speak.

Died of what? Asbestosis requires *long term* exposure, and an autopsy
that reveals fibres in the lungs, but there are plenty of lung diseases

vehicle clutch centre plates and brake shoes/pads had asbestos. This
means every major road had asbestos fibres littered all around, blowing
in the wind.

Local back street car repairer died when he was about 68 from lung
cancer. He had never smoked in his life, but it was assumed that a
lifetime breathing in petrol fumes and using an air-line to blow
the dust out of calipers and drums was the cause.

Going onto an old asbestos-cement roof without using crawling
boards is utterly stupid. Old asbestos is very unforegiving and
gives no creaky warning, but just shatters and through you go.

No, not like those at all because corrugated asbestos tends to be
nailed to joists with quite a wide spacing and no tile battens,
sarking or anthing else. Just self-supporting asbestos sheeting,
whereas a proper roof will have rafters generally spaced no more
than 18 inches apart with cross nailed tile battens too, so you have
more chance of just putting one foot/leg through
