ERMA report on safety of CCA treated timber

ERMA report on safety of CCA treated timber valuable

An Environmental Risk Management Report finding that CCA treated timber has been used for many years in New Zealand without discernable health effects makes valuable points about the safe use and handling of the product, Carter Holt Harvey said today.

Devon McLean, CHH Chief Operating Officer believed it was important that new research and literature regarding CCA treated timber was independently reviewed following debates about the product in the United States, and ERMA was the appropriate scientific body to do this.

“CCA has been a registered timber treatment in New Zealand for over 50 years. We are pleased this thorough report did not find any evidence of health effects from the use of CCA treated timber here though it does provide a timely reminder of the need for care in its use and handling,” Mr McLean said.

CCA is currently one of the most effective timber preservation treatments against insect attack and rot caused by fungal decay. It is commonly used in poles, fence-posts, building foundations and piles, decking, horticulture, and in landscaping such as retaining walls, and pergolas.

“We recognise that the use of CCA treated timber in play areas is an area of potential concern. Although the ERMA report found no evidence of health effects from its use, we will continue to provide advice on existing alternatives to CCA as required and we continue to support industry initiatives to develop timber treatments for these areas.”

“We will also continue our education and training programmes for customers and staff on the correct use and handling of CCA treated timber. Carter Holt Harvey wants to ensure this highly effective timber treatment continues to be used safely in New Zealand.”
