Overview of Pressure Treated Wood

Overview of Pressure Treated Wood

Pressure treated wood is a popular choice for outdoor construction projects such as decks, fences, and retaining walls. It’s created by injecting chemicals into the wood to make it resistant to rot and insect damage.

However, this process can have negative effects on both human health and the environment. The chemicals used in pressure-treated wood contain toxic substances that can leach out over time or be released when burned or disposed of improperly.

In addition to these concerns, there are also aesthetic considerations with pressure treated wood. While it may look great initially, over time it tends to fade and lose its color due to exposure from sunlight and weathering.

Fortunately, there are many alternatives available that offer similar durability without the harmful side effects of pressure-treated lumber.

Common Concerns With Pressure Treated Wood

Common Concerns With Pressure Treated Wood

It comes with some common concerns that homeowners should be aware of. One of the biggest concerns is the use of chemicals in pressure-treated wood to prevent rot and insect damage.

The most commonly used chemical in pressure-treated wood is chromated copper arsenate (CCA), which has been linked to health problems such as cancer.

Another concern with pressure treated wood is its impact on the environment. CCA-treated lumber cannot be burned or recycled due to its toxic nature, so it must be disposed of properly at a hazardous waste facility.

In addition to these health and environmental concerns, there are also aesthetic issues associated with using pressure treated lumber. Over time, it can warp or crack due to exposure to moisture and sunlight.

Health Concerns and Precautions

Health Concerns and Precautions

The chemicals used in the treatment process can leach out over time and pose a risk to your health if you come into contact with them. This is especially true if you’re working with the wood on a regular basis or have children who play near it.

To minimize your exposure to these harmful chemicals, there are several precautions that you can take when handling pressure treated wood. First and foremost, always wear gloves and protective clothing when working with this type of material.

You should also avoid cutting or sanding the wood indoors where dust particles could become airborne.
