Treated lumber in for changes By KATHY JUMPER
Use of arsenic in process will be banned after end of year; industry predicts much-higher prices.
Fact Sheet: Chromated Copper Arsenate (CCA) -Treated Wood Used in Playground Equipment U.S. Consumer Product Safety Commission
There are a number of non-arsenic containing preservatives that have been registered by EPA to pressure-treat wood for consumer applications. ACQ (ammonium copper quaternary) and copper boron azole (CBA) are common ones. Some wood treated with these preservatives is already available at retail outlets such as home improvement stores. In addition, playground equipment made of other non-arsenic containing components is also available (e.g. woods such as cedar and redwood and non-wood alternatives such as metals and plastics).
Facts about Pressure Treated Wood Canadian Institute of Treated Wood
As of December 31, 2003, wood treaters will no longer use CCA to treat wood intended for non-industrial uses such as play structures, decks, picnic tables, landscaping timbers, residential fencing, patios, walkways and boardwalks. Remaining stocks of wood treated prior to December 31, 2003 can still be sold in stores and be used for residential construction in Canada. This is a voluntary transition designed to reduce the amount of arsenic released in the environment by replacing it with a new generation of wood preservatives.
Pressure-Treated Wood: The Next Generation by Daniel S. Morrison, Fine Homebuilding
The EPA is banning CCA lumber. The replacements are safer, but they may change how you build a deck.
Nearly 40 million lb. of arsenic is used in this country every year, and most of it goes into the pressure-treated wood that we use to build decks and playgrounds. But that all changes Jan. 1, 2004. The Environmental Protection Agency (EPA) is banning chromated copper arsenate (CCA) as a preservative for wood intended for residential use (except for the lumber that is used in permanent wood foundations). CCA-treated lumber will still be available for industrial and agricultural use, however.------------------------------------------- posted 7:18 AM :: reference link ::
