All cyanoacrylates are dangerous. I don't use them (any of them) much any more. I have been building for 59 years, and even though I didn't develop any adverse reactions to the CA's, I just don't like the stuff. If you use an accelerator, the joints are more brittle, than if you don't. I went back to using alaphatics (Titebond, Titebond II and Elmers). You get more work time, and the joints are much more sandable. Yes, Cyanoacrylates can be some very nasty stuff. I would reccomend staying away from it as much as possible.
