Australia restricts CCA treatments
Copper chrome arsenate (CCA) wood preservatives have been declared restricted products by the Australian Pesticides and Veterinary Medicines Authority (APVMA) from July 1st. They can only be supplied to and used by suitably trained people, the APVMA points out. The Authority began a review of CCA timber treatments in 2003. In 2005, it advised that they should not be used on timber for playground equipment or other high-contact structures.
