I also posted this in the Safety forum:
•I often use my bare fingers around CA and will get it on my hands. This usually isn’t a big deal, however I recently let a good deal of it build up rapidly, and got a nice little burn. The burn was small, but the heat generated by the curing CA glue was very significant and extremely painful. I believe the heat caused the burn, and not a chemical reaction with my skin. The MSDS for CA glue also warns against using cotton gloves, as apparently CA will react with cotton, although I imagine using CA with any pourous glove at least has the potential of leaving one wearing the gloves for a while!
•CA glue vapors will burn your eyes. So wear safety glasses/goggles, and don’t stand directly over your work, especially if you are applying the glue in a manner which will lead to vaporization (e.g. applying glue to a pen rotating on a lathe). I have a fan behind me which helps blow vapors and dust away from me as I work, and this has helped.
•Be aware that CA glue will react with Boiled Linseed Oil. I use a CA/BSL combo as a finish on pens. I recently tried to make a mixture of the two so that I would have a consistent ratio for my finish. I combined approximately .25oz of each in a little plastic sqeeze bottle. The two did not readily mix. However upon shaking the two reacted, giving off significant heat (I couldn’t hold the bottle), and the mixture quickly solidified. The reaction was not quick (~1min).
