How unsafe is it to breathe in or touch polyurethane wood varnish?
I used some in woodshop class...yesterday I had to apply the stuff in an enclosed space (the door was open, but the room was very small), so I had to breathe some of the varnish vapors. (I worked for about half an hour that time) Some of the stuff also got on me when my latex gloves broke twice, allowing the stuff to get on my fingers.
So, is there any lasting health concerns resulting from either accidentally breathing in polyurethane varnish vapors for half an hour, or getting into contact with liquid polyurethane? Thanks a lot.

The main thing that you want to look out for in polyurethanes is if they have a activator or hardner to to help make it dry. These chemicals contain what is called iscocyanites wich can cause cancer. Now most of these products are usually found more in the auto body field.Although any time you are working with any type of chemical they have what is called a M.S.D.S. sheet on it wich will explain all the procedures if there was an emergency with this product you should be able to check the product for health concerns as well.

if you feel fine right now, and dont have any kind of sores on your fingers, it should be okay. just be more careful when it comes to shop class.
and if you felt a little lightheaded after breathing the stuff in, that happens a lot with harsh chemicals. like i said, just be more careful. maybe start wearing leather gloves instead of rubber, and wear one of those masks that cover your mouth and nose. :)
sorry if i wasnt of anymore help, but i dont take shop. but my dads a woodworker and is around this stuff all the time. hes just fine, so you should be too. besides, if the chemicals in that substance were harmful, i doubt they'd let you be around it in school.
take care!
