Concern
    There has been much concern about Chromated Copper Arsenate treated lumber by the public as well as the lumber industry. The public is worried that the levels of carcinogens that can be leaked from the treated lumber may pose a health risk to those who come in contact. Most studies suggest that risk is minimal, however given the status of "minimal risk" hasn't quelled the publics concern. Some have suggestes to abstain from using treated lumber, however the lifespan of untreaded lumber is significantly limited to that of its treated counterpart. With the expense of replacing damaged wood or risking structural failure, treated wood wins favor. Other synthetic materials can be used but they can be more expensive and tend to not have the "feel" of a structure that was intended to be wooden. The alternative that keeps structures standing and the public safe is to seal the treated wood.
Research
    Several researchers have reported that stains/sealants/coatings can reduce the rate of leaching CCA compounds from treated wood and that the effectiveness of these coating materials over time varies greatly, depending on the type of surface coating used and environmental conditions effecting the wood. Stilwell (1998) reported over 90% reduction in dislodgeable arsenic residues from CCA-treated wood surfaces coated with a oil-based alkyl resins for samples tested one year after a sealant was applied. CDHS (1987) reported 96%, and 82% reductions in dislodgeable arsenic from stained CCA-treated wood surfaces after one month and 2 years, respectively.
EPA Report
    In a report dated May 11th 2005, the EPA states "If consumers are concerned with potential exposures that may result from contact with CCA-treated wood, they may treat the structure with a sealant. Available data suggests that application of penetrating coatings to your deck or other residential CCA-treated structures can be effective in reducing dislodgeable arsenic. Oil or water-based stains that can penetrate wood surfaces are more effective in this regard than products such s paint, which forms a film on wood surfaces. This is because paints and other film-formers such as elastic vinyl products can chip or flake, requiring scraping or sanding for removal which can increase a consumer's exposure to arsenic. By selecting the proper coating for the initial application and re-coating, consumers can help minimize the potential arsenic exposure caused by scraping, sanding and power washing."

Honorable Thomas H. Moore from the U.S. Consumer Product Safety Commission released a statement dated May 11, 2005, entitled "Evaluation of the Effectiveness of Surface Coatings in Reducing Dislodgeable Arsenic from New Wood Pressure-Treated with Chromated Copper Arsenate (CCA)." He added, "This agency's job is to inform and protect the public. The Commission was concerned enough to do the mitigation study and to release an interim report about it to the public. We should make sure that the underlying message is not obscured. If you have young childern and they play on CCA pressure-treated wood in your backyard, you should seriously consider treating that structure with a penetrating stain or sealant to reduce the amount or arsenic to which children are exposed."
Report to Legislature
    A report authored by Kenneth Kizer, M.D., Director of Health Services outlines the "Evaluation of Hazards by the Use of Wood Preservatives on Playground Equipment." This report was issued in 1987 to the California Legislature as an investigation into the health hazard posed to children by chemical wood preservatives used on playground equipment.

    The report isolates an example of acceptable levels of toxicity on a playground structure after being sealed. At Cedar Rose Park in Berkeley, CA surface arsenic residues collected on gauze-wipe samples were reduced from a range of 31-314 ug/100cm2 before sealing to 1-13 ug/100cm2 after sealing. An article in the Berkeley Gazette points out that Deck and Shake was used in the sealing of the playground.
Independant Research
    Since the testing of this playground in 1987, Deck And Shake has been reformulated to better protect wood. A recent test taken at Robinson School in MA shown a reduction to .003ug/100cm2 to .01ug/100cm2. These levels are far below the detectible limit of 6.3ug/100cm2 in the CPSC(Consumer Safety Product Commission) study.

    Deck and Shake not only protects wooden structures, but it also protects the environment. A study performed by Central Testing Laboratories in Crystal River, Fl found significantly low Arsenic levels in the surrounding soils of their sealed playground.
