: I'm not so sure it's the vapors you need to be concerned with when working
: with epoxy. Rather, you certainly must be concerned about the dust. That
: said, it?s never a bad idea to protect yourself from toxic fumes though.

In fact, though not so strong smelling as poly resins, epoxy fumes can cause liver damage.

I use a North 7700-30 silicone mask with 7500-1 Organic vapour filters fitted with 7506N95 Dust filters and adapter. Total cost was about $50 CDN (and I have three extras if anyone is interested)

The mask should be professionally fitted, but Medium seems to fit most people...
