I don't worry about it. People have been draining antifoul into that piece of ground for decades, most of it being older, much more toxic varieties. I'm not going to make it any worse than it already is, and I doubt it's as bad as the site of a Victorian arsenic factory my friend nearly bought a house on, or the strip of land at my office location that was used as a chemical store during the war and now cannot be used for anything where people will regularly be present.

Thanks for your concern.
I really don't think Bosun Higgs (and his doctor), Kengill, Zen Zero and I are idiots. Or that you should be calling us idiots.
You have an opinion, we have a different one.
These forums are a hot-bed of people who will not accept that others may have a different opinion.
The issue of despoiling other people's boats doesn't apply to my preparation as I do it at home.

Phil,
I've seen the affect of respiratory illness at close quarters. It's not pleasant. It is fatal.
The onset of the illness was years after the cause.
Of course you are free to do as you wish. I would just ask you to consider if you are being wise.

Lakesailor - speak for yourself; I am a complete idiot!

Fair enough, but most (if not all) of people that I notice dry sanding have made the effort to wear PPE themselves so presumably feel there is some risk to thier health but apparantly not to anybody else.

i have always wet sanded , but i always end up looking like papa smurf , i had consideres buying an air compressor from aldi & an air sander thinking that the antifoul dust will be blown into the collection bag, would this work ?

I don't know about that but it certainly kills grass. I scraped the antifoul off my Leisure 17 in my back garden 7 years ago and there is still a bald patch in the lawn.

It's a matter of degree and proportionality, isn't it Lakey. It's sensible not to voluntarily give yourself or anyone else an exposure to a cloud of sanded antifoul, but it seems clear that if you do so the risks from s single exposure are small. Otherwise, the members of my club would be dropping like flies.
However we seem to have questioned someone on their academic subject which is almost as bad as questioning the size of his willy.
and hence the intemperate response.

Yup. I didn't get where I am today by not challenging expert opinion.
I should add that I wear PPE when sanding my antifoul. No body else is affected by my work.

AFAIK in NSW only wet blasting is allowed in yards and the barnacles and old af is meant to be collected and disposed of. In practice someone shovels the solids from the slip into a skip but the liquids run off. Grit blasting or water blasting is used to get back to gelcoat. I have never seen anyone dry sanding af but our boat is normally only out of the water for a couple of days pa.

My last posting on this thread
1. I didn't call dry sanders idiots, the OP did. I'm just agreeing with him. I accept that "idiot" may have more than one meaning, I meant "foolish person", not "mental retard". My intention was not to be insulting and it might have been better, in the context of the OP's question, had I written "extremely foolish, showing a total disregard for the health and safety of others and for the protection of the environment". You may wear PPE; where does your sanding dust go?
2. Presumably Bosun Higgs's doctor phoned the Poisons Information Line. That deals with acute poisoning and its immediate treatment; I have no difficulty with the response that BH quotes. You will not get acute poisoning from dry antifouling dust. You may get mitochondrial damage from absorbing metallic compounds and you may get respiratory disease from the respirable particulates - that may be acute or chronic, but it is nothing to do with poisoning.
3. If you read my post again you will see that I did not suggest that you could not have a different opinion. You are perfectly entitled to yours; my comment was that yours was based on ignorance. That remains a factually correct observation.
4. These forums are also a hot-bed of people who make bold assertions based on ignorance. I chose to post on this thread because of the potentially harmful health and environmental effects of the point of view that you and some others were expressing. I have done that and so have nothing more to add.

Andy,
Many thanks. I, at least, appreciated your input.

apologies for the thread drift, but why on earth did the Plymouth Uni team feel it necessary to do their research in Malta rather than in the many boatyards around their base?
could it have been the lure of the sunshine, or perhaps the possibility that laxer working practices might allow them to come back with a more exciting result, which might justify "funding" (I.e. Taxpayers' money) to have another jolly?
I know that the subject arouses strong feelings among forumites, but the spending cuts may not be entirely wasted if the spenders of taxpayers' money actually begin to think a little harder about where it comes from and a little less about what fun it could be to spend it.

Maybe because it's more fun doing it there? Maybe because the Maltese government sponsored the research?

Or perhaps the students paid all their own expenses and it was cheaper going to Malta than staying on the South Coast, even in Hall during Vac' ??
Grumpy by name and nature?

Perhaps one of the students is Maltese and his grandad owns the boatyard?
If they didn't say why in the paper, then we just don't know.

Quite agree, calling people names because they differ with your opinion is immature to say the least, respect for others, whether it's their opinons or property should, at the very least in our boating community be par for the course.
Covering other peoples boats with dust is not acceptable, and care not so to do should be taken, as to whether said dust is harmfull is another matter altogether.
I do not want to get this into another 'environmental/climate' thread, but we are very much inthrall to those who would find something wrong with whatever activity is taking place, and the old common sense is no longer so common anymore.
I do mine in Italy, not seen anyone yet wetsanding, most use masks and overalls, and the dust is washed away into the yard pool. Over some 60 years of use and the pool is clear with lots healthy weed.

I've dry sanded...... Admittedly not the whole boat but just as some surface preparation for fresh stuff to go on top on the worse bits.
I wore a proper mask, not one of those paper cr4p ones and spent about 20 mins with some 80 grit on an orbital sander.
I found it a very effective way of removing the old paint. As previously mentioned, a dust extractor would have been awesome!
I think there are a couple of points worth mentioning here.
Firstly, if you're going to make a mess that can spread then of course you should use dust sheets to minimise this but this brings me onto my second point -Boatyards are a working environment. People will be working on their boats. Noise, paint fumes, styrene fumes, dust are always going to be found in such places.
I won't comment on the toxicology aspect of this as there are several posts showing a bit of attitude towards this and that is not what I come here for.
I take the view that a few quid spent on a decent mask to protect me from whatever nasties may or may not be present is money well spent to protect me.
