I have purchased a repurposed piece of barn wood (a beam). It was kiln-dried and fumigated by the company that sold it to me. I mentioned the beam to a friend who is experienced with wood work and living in Europe. He said if the wood was fumigated, it was no longer safe for indoor use and a health hazard. I contacted the seller to see what chemicals were used to fumigate the wood but don't know if I will get that information.
I love the beam and will keep it no matter what, but is it safe to use indoors? How can I find that out? What if I cant get an information about the chemicals used, is there any ways to have it tested?
Best Answer
Most likely it was fumigated with Sulfuryl fluoride
According to Cornell university, it quickly breaks down
If it's been some time since the fumigation, it's likely safe enough to use indoors
