Dental assistants in frequent contact with the methacrylate monomer did sometimes get neuropathy from it ... but they didn't wear gloves. HIGHLY flammable, though. Despite my reaction to the monomer's smell, it seems less harmful than methanol, which hardly seemed toxic at all from its odor. Very deceptive, methanol! By ingestion: Usual fatal dose: 100-125 milliliters. The OSHA allowed exposure level for methanol, at 200 ppm, is twice that of the methacrylate monomer, though, at 100 ppm. For comparison, here's the safety sheet for methanol: http://www.jtbaker.com/msds/englishhtml/m2015.htm If we just treat these things we use for our work with respect ..........
