I did go to the IARC site, and while it is true that styrene is  
listed as a "possible carcinogen", they also say that after 25 or so  
studies, it is still inconclusive. The tests that they were running  
were with people, as you mention, in boat building and tub and shower  
manufacture. These are people with a LOT of exposure. All Day, every  
So, while I think it is good to know that there could be some  
exposure issues with styrene, if you use it a lot, I think it is  
pretty darn safe. Putting up a "For Sale" sign (made of styrene) has  
about the same exposure as making some eyeballs. Carving a sock  
puppet head out of styrofoam (made from polystyrene) would have a  
much higher exposure, as it sands into particulate matter, which is  
easily inhaled. Drinking a cup of coffee out of a styrofoam cup?  I  
would think even using a sharpie marker is more toxic than making  
styrene eyeballs.

I just think that, while Mark's information is probably correct, it  
seems overly alarmist and just doesn't really apply to what we do,  
unless you start manufacturing thousands of puppets a year. Anyone  
out there doing that?
