2K paint
Folks, a bit of a laugh for Thursday, I just picked this off an ebay auction:
"Brand new Gerson respirator.
Field tested with isocyanates (B1 classification) to in excess of 40 hours, this mask offers the user maximum protection without the need for air
fed breathing equipment. This mask comes with 1 pair of filters and 1 pair of pre-filters.
Replacement filters and pre-filters are available making this ideal for use by high volume paintshops and individuals alike.
N.B. 'Government legislation states that anybody spraying with isocyanates should always use a positive pressure air fed full face respiratory
breathing system for full protection'.
The same government health and safety advises that trained monkeys should only be used as guard dogs if supervised by ducks with an IQ higher than the
average politician.
We have been supplying these masks for over 2 years to the trade and our eBay customers and have never had any returned.
Please read our terms and conditions before purchasing"
Now has he had no returns because it is a good product or are all the people who bought one dead from isocynoacrylate poisoning 
This is obviously much cheaper than an air fed mask for low volume spraying at home. what does the team think?

Dont use it for Isocyanates, full face positive pressure fed mask is for a reason, the poison can enter via your eyes as well as through breathing.
You should also wear a full overall including hood and gloves, and work in a spray booth with filtered extraction to prevent toxins reaching the
atmosphere, we are talking cyanide here...

r1_pete, I'm not splitting hairs here, forgive me, I'm a Chemist. It's not entirely accurate to place the risk on
'cyanide'. That said, yes, classic cyanide toxicity is still an issue, it's just that 'cyanide' isn't available
until the biochemistry and chemistry have done their thing.
It won't get that far, the reactivity of the compounds with your respiratory system will cause you enough life-threatening problems before the
metabolites and systemic poisoning are an issue. Jury is still out as regards in-vivo cancer potency.
Essentially a carbon filter should (in theory) adsorb the compounds, no problem, they're VERY good. You could then cover all your mucous
membranes (eyes, etc.). For limited exposure (car panel, well ventilated garage), you could get away with it without apparent serious injury, but any
barrier failure could result in death (particularly if you're already sensitised). No sane individual would consider doing this, but there are
insane people out there. DON'T EVEN THINK ABOUT IT. I've heard it all, people contemplating using scuba gear...
Any atmospheric dispersal of (any) paint/solvent system is extremely hazardous (either short or long term). Acrylic/acrylates are hardly a safe
alternative....
USE AN AIRFED HELMET/VISOR, PUT A CARBON FILTER IN THE LINE, DON'T PUT THE SUPPLY COMPRESSOR ANYWHERE NEAR!!! EXPOSE NO SKIN.

I thought mdern paints had moved away from the use of Isocyanate's anyway and are now largely water based??

Apart from being very highly toxic the big problem with isocyanate paints is over spray. Any spray that either misses or bounces off the panel
carries very far and is very very tacky -- once it is on a surface you won't shift it short of using wet & dry paper..
HVLP is the way to go --- great finish virtually no overspray and it uses about 1/4 of the paint.

So I guess we assume all the people who bought these masks didn't complain because they are dead!
So can I assume that entering a garage where paint has recently been sprayed and is to some extent in the air and it is very smelly is likely to cause
serious health problems?
Are symptoms going to be evident quickly or is this a cumulative poison effect?
As I am only likely to paint a handful of cars in my life am I as at great a risk as someone working in a spray booth 40 hours a week?
Questions, questions!
