What is Pressure Treated Deck Wood? |
|
Answer:
Pressure-treated deck wood is a wood product Pressure-treating of lumber products became popular after chromated copper arsenate (CCA) was developed in India during the 1930s. The Bell Telephone Company purchased the patent rights from the Indian doctor who developed it, most likely for preserving wooden telephone poles. Eventually, the process and product for treating wood with CCA made it to the public market place. Use of CCA-treated lumber materials spread like wildfire in the U.S., as developers, builders, and homeowners anxiously took to a product which promised long-lasting, low maintenance, and attractive appearance. Unfortunately, nobody paid attention to the fact that CCA chemical formulation contains arsenic (and chrome and copper), and is now considered hazardous. CCA containing materials were used widely on children's play-scapes, picnic tables and many other outdoor items. CCA containing materials were beginning to fill landfills as well, which created environmental cleanup or control issues. CCA is now used as a wood preservative only in industrial or commercial applications, but is not used for publicly available materials. Instead, other, allegedly much safer, pressure treating chemicals have been developed to replace the hazardous CCAs. As with any chemically treated items, use, handling, cutting, etc. should always be done in accordance with manufacturers' recommendations and guidelines. Trackback(0)
