How to Use Pressure-Treated Lumber
Pressure-treated wood is typically used for applications where the lumber comes into direct contact with the ground because it is resistant to insects, rot and damage. Because pressure-treated wood contains chemicals that can be both toxic and carcinogenic, always follow safety precautions during handling. Only use pressure-treated lumber in appropriate applications. Use pressure-treated wood for mailbox or light posts and children's play equipment, such as swing sets.
There are different types of pressure-treated wood; determine the manner of use before selecting the appropriate type of wood. For example, the amount of chemicals used to treat the wood may dictate how the wood will be used.

Tips & Warnings
Cut pressure-treated wood outside if possible, and use respiratory protection, such as a face mask or respirator with a filter. Use work gloves to avoid splinters. Splinters from pressure-treated wood can become infected. Some people may experience an allergic reaction to direct skin contact or splintering.
Follow manufacturer's instructions for using materials. Avoid using pressure-treated wood in any applications where it would come into contact with food, such as in raised garden beds, or for building compost piles. Do not use pressure-treated wood for applications where drinking water or animal feed may become contaminated.
