I work in Electrics for my full time job and so have some understanding of Epoxys.
I know the hardener tends to be the more Hazardous part of the two.
As for green stuff generally....well I am skeptical towards some of what's been said.
No disagreements on BPA, it's in an incredibly large number of plastics, a big issue being bottled water.
When it hits a certain temperature (I can't for the life of me remember what it is), the Petroleum leaks into the water from the plastic, so never drink water from a bottle that's warm, or has been allowed to get warm.
As for skin contact...eeeh...not really sold on that one.
I meaning washing your hands afterwards, shouldn't be done ONLY because of hazards, it should be good hygiene.
EDIT: I CAN believe it though for pro-create, in large enough mixes, it does give off a faint smell.
. So it's only dangerous if you are in contact with large quantities, otherwise it's fairly safe, unless you eat it or something like that.
