Is treated pine toxic?
Also, is treated timber toxic?
CCA treated timber (also commonly called tanalised timber) contains copper, chromium and arsenic, which is a toxic chemical mixture but is relatively inert once fixed in the timber. However, it is not recommended in skin contact use such as children's playground equipment and hand rails.
In this manner, can you use treated pine inside?
The simple answer is pressure-treated lumber can be used in any interior application except cutting boards and countertops. Some have also asked, after they've found pressure-treated lumber installed inside their homes, if there is any danger in having it indoors. The answer is no.
While ACQ and LOSP treated pine decking boards are considered safer than CCA, it is always advisable to wear a face mask, protective eyewear and gloves when working with treated pine.
