Efforts to protect Douglas fir lumber with CCA pressure treatment practices have usually proven unsuccessful. Because there have been instances of structure failure*, local and state building officials are on the lookout for insufficiently treated Douglas fir lumber resulting from misinterpretations of the AWPA standards.

Chemonite is the registered trade name for Ammoniacal Copper Zinc Arsenate (ACZA). It was initially formulated at the University of California in the 1920's, and developed for commercial use in the 1940's, by J.H. Baxter, a Califomia timber and treatment company, which continues to hold the product's license today. Chemonitetreated wood has maintained it's structural integrity for over 50 years, with no reported removal due to failure.
