FOR CCA PRESSURE<br />
TREATED TIMBER<br />
The Chromated Copper Arsenate<br />
(CCA) preservative used <strong>to</strong> treat<br />
<strong>outdoor</strong> Radiata Pine reacts with the<br />
wood <strong>to</strong> form chemical complexes<br />
that are highly insoluble and leach<br />
resistant. The CCA preservative<br />
penetrates deeply in<strong>to</strong> and will<br />
remain in the wood for a long<br />
period of time. However, some<br />
preservative may migrate from the<br />
preserved wood in<strong>to</strong> surrounding<br />
soil over time and there may also be<br />
incidental contact with skin during<br />
construction or use.<br />
