Chromated Copper Arsenate Awareness

From the American Wood Protection Association (AWPA):

“Builders and contractors have some pretty big shoes to fill.  They are the critical link between the designers, the local code official, and the owners or residents of the building.  A builder’s reputation is usually based on the quality of the finished product, so the best builders rely on AWPA to write the standards for the treated wood products they use in their structures.”

From the Western Wood Preservers Institute (WWPI):

“Since 2004, the approved uses of CCA-treated wood do not include residential structures. Converting an agricultural structure into a residence – such as the “barndominiums” you advertise – is not an EPA-approved use of CCA-treated wood.” -WWPI

From the Environmental Protection Agency (EPA):

“Prior to 2004, wood treated with chromated arsenicals was used in residential structures such as decks and playsets.

  • In December 2003, chromated arsenicals manufacturers voluntarily discontinued manufacturing chromated arsenicals-treated wood products for homeowner uses.
  • However, EPA does not require the removal of existing structures made with wood treated with chromated arsenicals or the surrounding soil.”

From the National Pesticide Information Center (NPIC):

“CCA residues on your skin do not get in your body. However, they may cause redness and swelling. Ingesting low levels over the long-term can lead to hair loss and skin changes including thickening or darkening of the skin. It can also increase the risk of skin, bladder, liver, and lung cancer over a lifetime.”
