Did you check the toxicology sections in the two safety sheets, to compare the monomer with methanol? The ingested lethal dose isn't all that different. Note also that the OSHA tolerance levels (200 ppm for methanol and 100 ppm for the monomer) have the monomer at a lower suggested tolerance level than the methanol. Note the fancy respirators they are suggesting, and the advice about using a hood or exhaust ventilation. Note also the section where it says that people who already have liver damage will show more reaction to less of the monomer than ordinary people. My family tends to have liver problems, and as kids my sister and I were exposed to way too much stuff which was kept in the house, like carbon tet and DDT, which aren't even available now. This could explain why I tend to go ballistic over fumes, which really bother me. Now, you can say, "well, that official advice is for people using lots and lots of it every day," which may be at least partly true. You may hate what I said, which is your prerogative. Nonetheless, I still feel that a little concern about using such materials is warranted, IMO. Now that I've read the data sheets, if I were asked about using the Acrilikey kit, I'd say, "yes, it does a good job on keys. Be sure to use the gloves, and I'd suggest doing it outside, or if you are friends with a chemistry teacher at a community college, maybe they'd let you use their hood." It helps that no one fixes a ton of keys day in day out, so any exposure isn't chronic. Susan -------------- next part -------------- An HTML attachment was scrubbed...
