Posted By Jane Watts Help! Haven't spoken to HSE. But their latest EH40 stuff says they're reviewing exposure limits on them at the mo. Haven't had experience of COSHH asessments and procedures we should have in place for using these substances. Can anyone help? Thanks in advance:)

Posted By Jane Watts I have looked at the coshh essentials website yes and we've decided not to use it as we don't feel it is that user friendly. It's very good for big processes, i.e. transferring flammable substances out of big vat and disposing of. But for generaly lab processes, i.e. using glue or lubricating sprays, it doesn't really capture what we're after. I know that isocyanates are singles out due to the level of their 'nastyness', however, couldn't find the info. Maybe i'll give the HSE a ring.

Posted By Jane Watts We use them as resin's, in moudling machines, so can't get round not using them....i don't think! I've got the data sheet, but i'm after 'common' precautions that should be taken. I have found some stuff of the technical indexes webpages.

Posted By Jane Watts Thanks all, i've since found out that they fall into one of two categories, either monomers or pre-polymers, one is worse than the other, monomer...I think.
