You can make your work area CA vapor, and paint fume free with a simple house fan and a window. Blow the air from the fan OUT the window and it sucks the vapor right out. You need to be a little close to the window fan but it works great. If you do this for years check out the fan blades. It will be coated with the CA you would have had in your lungs! Second words of warning CA fumes can burn your eyes very badly too. I heard (though it never happened to me) that the fumes can glue your eye shut. As for a little history lesson back in Vietnam they used to give solders spray cans of CA. If someone got a large battle wound they would spray the CA on the wound to stop massive bleeding. It saved a ton of lives and is still used in surgery to this day for a lot of procedures.
