But on the very same website it also says this https://www.hse.gov.uk/mvr/bodyshop/myths/myth3.htmSorry Parm but even our own hse says it's wrong, see the link https://www.hse.gov.uk/mvr/bodyshop/myths/myth9.htm
From that link, the line that makes it pretty clear for me is: 'only air-fed breathing apparatus is suitable for isocyanate spraying (filtering face masks are not acceptable)'
I don't do any 2k work at all but if I did I know what I'd be using!
