Oh, crap!
Sigh! That means I have to reconsider this whole thing. I am so sensitive to "stuff" it has forced me to revision how I work and with what I work, changing my "career" and so on.
One more thing to consider
Perhaps I could remove all the wood (or "plates" as it were), wearing a respirator and cover the lot with epoxy or lacquer, encapsulating the fungicide.
This is a downer, TBH. I thought that I could pull the trigger when the real weight was published, but this is a real concern that could render a purchase useless to me.
