I have some questions about the safety of wood which has been treated for outdoor use. My understanding is that the EPA has said wood treated with 1)Penta, 2)creosote, or 3) arsenic compounds is not only unsafe during application of the preserative, but also unsafe after application. Such wood must be (at least) treated with a sealer. Do two coats of shellac suffice, or should one replace the treated wood? What about Wolmanized (or similar) woods? The Koppers Co. (who own the trademark) claim that their process is safe. Is there any confirmation/contradiction of this? Please reply directly by mail. I will summarize for the net.
