Pressure Treated
Pressure treated lumber and bottom plate of wall construction.
As you might or might not know the lumber with a green or brown tint and usually containing a pattern of indentions on all faces of the board is called pressure treated wood. In construction applications this wood is usually found in areas of dampness (i.e. under the home) as part of a raised floor or a joist system for decking. For a long time this was a hazardous material with which to work. On December 31, 2003, the US wood treatment industry stopped treating residential lumber with arsenic and chromium (chromate copper arsenate, or CCA). This was a voluntary agreement with the United States Environmental Protection Agency; copper based pesticides replaced CCA.
Today many organizations still feel the practice of pressure treating wood is harmful to the occupants and environment. There are alternatives to these products.
