This course reviews: the manufacturing process for pressure-treated wood; types of preservative treatments and the required levels of retention as dictated by the end-use application, desired service life and exposure conditions; American Wood Protection Association (AWPA) Use Category standards; current issues concerning preserved wood in residential and commercial construction; and Best Management Practices (BMPs) for aquatic uses.
