I understand pretty much the importance of gloves, ventilation, respirators and eye protection but the wikipedia entry for Bisphemol A makes for an overwhelmingly long read scattered with some quite alarming comments.
So id like to clear up a few things.

Gloves - i wear gloves to protect myself from the sticky stuff and sanding dust but should i be wearing them when i demold? ie does the blush contain bisphemol A or anything else i should be concerned about.

Eye protection - I wear glasses when i work and back them up with safety glasses when im cutting or machining compotes. However is it the fumes i should be worrying about and hence should be wearing goggles (even un-vented goggles ?)? I did do this for a while but found they steamed up so much as to cause more danger by blinding me. If i should put them back on how do i stop them from steaming up?

Respirators and ventilation - i work i n a shed so when im wet laying i leave a window open and have an extractor ( bathroom ) drawing from a channel drilled out along its length that runs along the length of my bench about 18 inches above it. I wear a 3m respirator with 6054 filters (+amonia) that my local h+S supplier tells me are the best for the job. I store the filters in zip seal bags between jobs ... Does this seem like adequate precaution.. Are these the best filters for the job ? Should i run a mile if i get an exotherm ?

Dust - use separate dust filters when sanding and machining. That i also store in zip sael bags

thanks for the advise carboncactus, FLD. Ive always been under the impression that epoxies where safer for the enthusiast, and with precaution i think thats probably true, however i was looking at another epoxy (resin research) that looked like a good product and had as a USP that it contained no phenols, they seemed to think that was great but i noticed that they use formaldehyde which ive been trying to avoid in glues!!
Im slightly surprised by the lack of really clear advise from manufacturers. Read the MSDS and do your own risk assessment seems to be the attitude, which may get them of the hook, and quite a hook it could be, but i would have thought clear advise on filter types, situations to avoid and maybe a few health and safety specific videos would go a long way in educating amateurs who cant really be expected to fully understand the risks involved. and considerably improve there ability to make proper risk assessments.
