Most likely the 2x4's were used under bundles of lumber for easier handling
during shipping. There is no telling where that wood may have been setting.

Hi,
My dad obsessively collected lumber scraps of 2x4 and larger which is
said he found outside a furniture factory. The wood is unfinished
however before burning it, I have to ask if the wood used in making of
upholstered sofa and chair frames is chemically treated at all?
Please help because I have probably 200 pounds of wood piled up and
need to decide to dispose of it or move it to my new house and use it
as fuel for my wood burning stoves.

Thanks so much!
Idas
