Wood Preservation
NAICS 321114 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in (1) treating wood sawed, planed, or shaped in other establishments with creosote or other preservatives, such as alkaline copper quat, copper azole, and sodium borates, to prevent decay and to protect against fire and insects and/or (2) sawing round wood poles, pilings, and posts and treating them with preservatives.
Start the review with pollution liability.
For Wood Preservation, the saved research highlights pollution liability, chemical handling and fire, workers' compensation. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What preservative chemistries are currently in use — creosote, copper-based compounds, borates, or others?
- Is there any known historical contamination on the site, or has the property been subject to environmental regulatory action?
- What is the proximity of the facility to surface water, wetlands, or municipal water sources?
- How is chemical waste and runoff currently managed — is there a spill containment system in place?
- Are treating operations performed for third parties on a toll-treating basis, or is all product sold as a finished goods manufacturer?
- What is the inspection and maintenance history of pressure-treating cylinders and retorts?
- For Wood Preservation, what should the underwriter know about use of creosote, pentachlorophenol, or chromated copper arsenate (cca)?
- For Wood Preservation, what should the underwriter know about known or suspected historical soil or groundwater contamination on the treating site?

Wood preservation facilities receive sawed, planed, or shaped lumber, poles, pilings, and posts, then treat them with chemical preservatives — including creosote, alkaline copper quat, copper azole, or sodium borates — using pressure-treating cylinders or other impregnation processes. Treated products are typically sold to utilities, construction contractors, agricultural suppliers, and landscaping distributors. Operations generally involve chemical storage, pressure vessel operation, and outdoor material staging yards.
