Don,
I raised this panic in the past about the CA.
One of my conclusions was that: im more sensitive to slower curing CA’s.
The slower it cures the more sensitive I’m.
Not to use it at all you cant in case of CA hinges, but you can avoid it and use aliphatic glues, they are as strong as CA, we run experiments at the end.
