IS it enough?

I would need to see hard, firsthand evidence in print that someone had something damaging happen; otherwise it could all be hearsay.
But maybe it was an issue with plywood being treated lumber? I know that it's sometimes treated w/ chemicals that prevent the growth of mold, prevent insect infestations, etc.. I guess that could be harmful.

Your both right, there have probably been advancements or maybe it some other off the wall case that has been stretched from the truth. It is a good idea as was pointed out to consider such things though.

Hope your building is going good! (today?)
