Are you treating your wood right?
Wood utility poles and crossarms are common objects seen throughout our communities along the streets and in our yards. These poles and crossarms are used to support and run electrical lines to our homes and businesses - making these products vital to our daily lives. Prolonging the useful life and structural integrity of these items is aided by treating the wood prior to installation.
Wood treatment refers to protecting wood from damage caused by insects, fungi, decay, climate and extreme weather conditions. Treating wood with the right chemical preservatives can extend the useful life and protect it from the harsh environment. Choosing the right wood preservative can save an utility time, frustration and money. The three most common wood treatments include:
- Pentacholorphenol (Penta)
- Chromated Copper Arsenate (CCA)
Pentacholorphenol (Penta) has been a preservative and maintenance staple of the Canadian and American utility industries for more than 60 years. Penta is a broad spectrum biocide and was previously used in herbicides, algaecides, fungicides and disinfectants. Today, the use of Penta in the U.S. and Canada is limited to wood preservation applied by trained-certified pesticide applicators. The production and use of Penta is regulated by the EPA and is an approved preservative in the American Wood Protection Association. (AWPA) Since its introduction in the utility industry, Penta has become the preferred wood preservative for poles and crossarms and is used extensively for treatment of laminated beams since it will neither wet the wood nor effect the glue joints. Penta can be used as a wood preservative for both Douglas Fir and Southern Yellow Pine crossarms.
Chromated Copper Arsenate (CCA) is a water based wood preservative. It is a mix of chromium, copper and arsenic. Recognized for the greenish tint it imparts to wood, CCA has been extremely common for many decades and is used primarly on Southern Yellow Pine poles and crossarms. DIS-TRAN Wood Products, LLC provides this alternative wood preservation to its customers making up about 5% of the crossarms we supply.
Creosote is one of the oldest of the commercial preservatives. It is made by distilling coal tar and is often thinned with a light oil such as diesel fuel or mineral spirits. The color of Creosote is usually dark brown to black with an oily appearance and odor. Most wood treated with Creosote is used in marine pilings, utility poles and railroad crossties.
