Is treated lumber safe?

Why can’t I burn treated lumber?
Although treated lumber is clean and free of fumes, it should not be burned. Burning treated wood releases chemicals into the air and in the ash. Federal and state laws require treated lumber to be burned in an approved facility.
Are there special handling instructions for treated lumber?
It’s best to wear gloves when handling treated lumber. When sawing or cutting treated lumber wear goggles and a dust mask, just as you would when working with untreated wood. The most important thing to remember is that treated lumber should not be burned.
I cut my treated wood and it looks like it isn’t treated in the middle – is this a faulty product?
No, the product is not faulty. You are typically seeing the heartwood which is naturally decay resistant. While it may appear to not have been treated, you do not need to be concerned.
What is the difference between wood treated for ground contact and above ground use?
Lumber that is acceptable for above ground use can function in a variety of ways but should not come in contact with the ground. When wood is required to come into contact with the ground, it’s important to use specially treated lumber that is designed and prepared for this purpose. Ground contact pressure treated lumber is developed to handle the additional moisture it encounters when meeting the ground.
Why should I use treated lumber?
Treated lumber is better equipped to handle attacks from enemies like termites, fungi, bacteria and rot.
