    2. Check for Surface Splits
    3. Look for an End Tag
    4. Find the Stamp
    5. Do the Smell Test
    6. Lumber Dimension
    7. Use a Swipe Test Kit or Wood Testing Kit
    8. Find the Retention Level

    Now let’s talk in detail about how to perform each of these steps.

    1. Observe the Color

    One of the primary characteristics of pressure-treated wood is its color, so one of the first things you should do is observe the color.

    You will often see a green tint or a dark brown color in pressure-treated wood. This coloring is a result of the chemicals used in the treatment process, which gives the wood its distinct color.

    However, keep in mind that the color may fade over time due to weather and exposure to the elements.

    2. Check for Surface Splits

    Second, you should check the surface of the wood for small, half-inch-long splits or cracks. 

    These splits appear on all sides of the wood and indicate where pressurized chemicals were injected during the treatment process.

    Remember that these splits are unique to pressed wood and are a clear sign of its treatment.

    3. Look for an End Tag

    Pressure-treated wood often comes with a final tag that contains important information.

    Therefore, at this step, you can identify the tag and confirm whether it is pressure-treated wood.

    I advise you to avoid using wood treated with Chromated Copper Arsenate (CCA)

    That’s because it contains a form of arsenic and has been banned since 2003 for outdoor-residential settings due to safety concerns.

    4. Find the Stamp

    In this step, you can check the wood for a stamp that provides information about the type of wood and its intended use.

    For example, a stamp that reads ‘FDN’ stands for foundation and is considered safe for use on structural elements beneath the home’s floors, such as basements.

    Wood treated with borate is also safe for indoor use and is usually stamped “Bor,” “Hi Bor,” or “Tim Bor.”  These stamps indicate safety for internal applications.

    5. Do the Smell Test

    If you cannot visually determine the wood treatment, take a piece of wood and take a deep breath.

    Note that treated wood typically has an odor similar to oil or highly toxic chemical compounds, except for CCA-treated wood, which has no distinct odor.

    6. Lumber Dimension

    Pressure-treated lumber is often slightly wider and thicker than regular lumber due to the leaching of chemicals during the treatment process.

    Check the dimensions of the wood. If it is significantly wider and thicker than normal wood, you should be aware that it can be treated.

    7. Use a Swipe Test Kit or Wood Testing Kit

    Many commercial laboratories offer swab test kits that help identify treated wood.

    These kits include wiping the wood surface and can confirm if the wood has undergone a pressure treatment.

    8. Find the Retention Level

    The retention level of pressure-treated wood indicates how much preservative remains in the wood after treatment.

    A higher retention level generally suggests more durable and well-preserved wood. 

    Remember that this information can be obtained from the wood’s specifications, fact sheets, or from the manufacturer.

    Incorporating these steps into identifying pressure-treated lumber will help you make informed decisions about its use, ensure safety, and select the right lumber for your specific project needs.

    I advise you to always follow safety guidelines and regulations when working with treated wood, especially if its use involves potential human contact or specific environmental considerations.
