Hi all - we have an old barn (1911) that is partly collasped. We plan to pull out the corners so it will finish dropping down, and burn it over the summer. My daughter said that old barn lumber was treated with arsenic, and that burning would be quite dangerous, releasing things into the air we might not want there. I haven't found much on the web about this, only that arsenic is still being used to treat wood. Does anyone have knowledge of the safety of burning old barns? Also, I was hoping to recycle some of the lumber. Is it safe to use? Life was much easier when I didn't know anything! [img]/forums/images/icons/smile.gif[/img] Thanks, Chris
