wood protection by use of approved naturally-durable wood, or wood that is preservative treated in accordance with AWPA Standard U1 for the species, product, p r esv ati ndu.T hc og z l preservative-treated wood is pressure treated. Non-pressure tr e am n sy p ic l vo b- d h are sprayed on untreated lumber to provide a surface barrier coating. Within IBC 's Section —Minimum Standards and Quality, Section requires preservative-treated lumber, timber, plywood, piles and poles comply with AWPA Standard U1 and Standard M4, "Standard for the Care of Preservative-Treated Wood Products," as applicable when used as supports for permanent structures subject to the service.
In the last three decades, extensive research has been conducted on reusing and recycling decommissioned preservative-treated wood. These studies include residual preservative retention in decommissioned utility poles (Arsenault ; Ruddick et al. ; Nurmi ; Osborne and Fox ; Cooper et al. , ; Lahiry ; Piao et al. a), interference of preservatives . include preservative treated shown in italics should not be included in the final specification.

The utility poles are then kiln dried and treated with CCA-C to meet the American Wood Protection Association Standards (AWPA) C-4 and UC- 4A, 4B and 4C, Latest Edition. We then go the extra mile and take all of our utility poles and process them further in accordance with AWPA standard A74 to meet Best Management Practices (BMP's) for the CCA. Wood fumigants are highly-effective internal treatments designed to protect wood utility poles from strength loss caused by internal decay and insect attack. How Wood Fumigants Work Fumigants are generally applied at or near the groundline area of a pole, where conditions for decay are optimal, by drilling a series of steeply angled holes.

The next generation utility pole is here with innovations that benefit pole treaters, utilities, linemen and the environment. The active ingredient in UltraPole™ NXT treated poles and UltraArm™ NXT crossarms, DCOI, has been standardized since by the American Wood Protection Association.
Durability of preservative-treated wood utility poles in Guam / Rodney C. DeGroot, Thomas H. : Rodney C. DeGroot. By Elaina Jackson, Pacific Wood Preserving Co. There are approximately million to million wood utility poles in service in the U. They are the backbone of overhead line construction, and most of these poles are pressure-treated with a wood preservative.
Utility poles are subjected to the harshest conditions that nature can dish out, from rain, ice and snow to insects and decay fungi. Preservatives infused into the poles through pressure, combined with wood's natural resilience, allow wood poles and crossarms to remain in service for 70 years or more.
Fact Sheet on Chemically Treated Wood Utility Poles • Wood preservatives used to chemically treat wood utility poles contain dangerous chemicals, including dioxins, which harm human health and the environment.
The last legal remaining use of pentachlorophenol (penta) is as a wood preservative in utility poles. similarto those used forstress-graded lumber, butthey Specifications for preservative-treated wood utility recognize no within-species qualitygradations.
Rated poles are to be given by the purchaser on the basis of poles simply meet or exceed minimum quality requirements detailed in other standards (i.e., AWPA specifications.
Treated Wood Utility Poles. Cobb Lumber Company has the ability to supply the wood pole to fit your needs. We can provide treatments in Creosote, CCA, Pentachlorophenol, and other EPA registered preservatives for your electric pole needs.
Transmission poles are available in Southern Yellow Pine, Douglas Fir, and Western Red Ceder. UltraPole NXT raises the bar in the utility industry with an oil-borne preservative that provides long-term efficacy with low environmental impact for wood utility poles and crossarms. The active ingredient in UltraPole NXT, DCOI, is not a restricted-use pesticide and is not persistent in soil.
The first step is to inventory the materials that go into a utility pole. Most utility poles are made of wood pressure-treated with some type of preservative to keep away woodpeckers, insects, fungi, and fires.
Many different types of trees can be used to make utility poles, including Douglas fir, Jack Pine, Lodgepole Pine, and Pacific Silver Fir. Welcome to by Poles, Inc. ® We are one of the nation’s leading suppliers of wood pole maintenance and inspection supplies.

Most poles produced in North America are cut from southern yellow pine. Southern yellow pine is fast growing, plus it is the strongest softwood for its weight. Because it grows tall and straight, its shape is well suited for utility poles.
It is also one of the most easily treated wood species. Continue reading at PRESERVATIVE TREATED WOOD LIFE or select a topic from the closely-related articles below, or see the complete ARTICLE INDEX. Or see. ARSENIC HAZARDS at BUILDINGS.

Polesaver reduces your environmental impact by reducing the loss of wood preservatives and pole replacement rates. Longer wooden utility pole life and reducing the need to replace poles helps reduce your CO2 output and environmental impact.
With environmental targets becoming of increasing importance, Polesaver can help your utility company.Natural durability, as used in this study, is the resistance of untreated wood to fungal decay in service above ground.
The time for more than half the test units of a given wood species to fail was termed the ‘average service life’ (Table 1). When failure of six or more units of one species. Christian Brischke, in Long-term Performance and Durability of Masonry Structures, Principles.
In contrast to chemical wood preservation, wood modification aims on enhancing the durability and dimensional stability of wood through chemical changes of the wood cell walls without the use of biocidal addition to durability, wood modification can improve other wood.
