CCA Treatment

by Website Administrator on March 29, 2016

The following extract on CCA was shared by The R&B Timber Group from Elictric Light & Power.

Copper chromated arsenate (CCA)-treated poles are commonplace, especially since the rising costs of oilborne systems have made a waterborne treatment more attractive economically. Some utilities prefer the softer oilborne treatments for lineman-climbing; however, some CCA treaters apply a refined hydrocarbon oil emulsion in the outer layer of the pole to combat this issue. The viscous oil additive serves as a lubricant, making the pole easier to climb.

CCA was effectively banned for residential lumber uses in 2003 when producers and the EPA reached a voluntary agreement to limit uses to industrial applications. Like penta, CCA is also a restricted-use pesticide.

Cedar poles can be effectively treated with CCA, although it is more common to see penta-treated cedar poles, either thermal butt or full-length treated. Several CCA suppliers exist, but there is only one supplier of the oil emulsion that makes the poles more climbable
