had to use some treated 2x4's for indoor rennovation, is this bad?

Question

This was done in my stepson's room. I could not find untreated 2x4's that were long enough so got treated. This is what the project was:

2x4's were cut and bolted to wall studs a perimeter around part of his bedroom wall. I then used some joist hangers and ended up with total of 5 rows of joists, so it sort of looked like a new floor above ground coming out from part of his wall. I then used untreated sheets of plywood covering the top and the bottom via screws. We sealed the platform edges with caulking and painted the platform. Then put his bed and shelving on it so it's now above ground and his computer desk is under it. I am just worried if fumes from the treated wood are going to get out of this or will they pretty much be sealed within the two sheets of untreated plywood and paint. Am I being overly paranoid? thanks!

Answer 1

Actually, you done good. The advantage of treated vs. untreated is resistance to termite and other hungry critters provided by treated wood. Untreated wood is cheaper because the idea is to sheath it between interior and exterior layers for structural purposes. Treated wood is generally used for exposed applications.Resistance to moisture,etc...Actually, the chemicals used nowadays aren't as toxic as creosote or some of the other smelly s-t they used to call preservatives.

Answer 2

Treated wood contains copper chromium arsenic. This is applied in a liquid form to soak in the wood. The warnings on the lumber purchased should have told you the only way to expose yourself to the toxicity of the chemicals is to cut the lumber. So you may have exposed yourself when the project was built unless a dust mask was worn. As far as fumes go, its highly unlikely since the wood is covered with sheathing and painted over. I would worry more about paint fumes than "treatment fumes"

Answer 3

Treated wood poses absolutely no problems.
When you stop and think-all the floor joists and plates are treated wood.. And also many people use treated wood for first floor underlay.

Don't worry.

Answer 4

you're fine. homes built on concrete slab use treated for the sill plate, the only thing seperating people from the sill plate is base board, paint and caulk. don't worry about it. you just spent extra on the wood.

Answer 5

Answer 7

Answer 8

Answer 9

as long as you dont have pets that can chew on it, and NEVER burn it because it has chemicals and it put off fumes from those,very toxic chemicals.

Answer 10

I'd worry! I don't think fumes can be sealed in that way.......

Is it too late to do it over ? I think it's a health hazard, but that's only my opinion....
