Blue Pill? or Red Pill?
Thanks matrixmom for pointing out something so obvious that most of us forget - Safety First! That goes for prop builders and their TOTs.Thanks guys...I was just going to use it for back side to anchor a light fixture. I was just going to stain it, to change the color - and eventually after halloween it will get tossed. I know a little chemistry so I didnt want a explosion if I try different paints etc.
they banned arsenic in treated wood in 2003It looks like pressure treated decking. IF it is, the wood is impregnated with arsenic to discourage wood worms and termites. The "blue" pressure treated wood is impregnated with another chemical that inhibits the growth of mold and mildew and is rated for use in homes (damp areas like bathrooms etc.) You could use the green pressure treated wood inside of interior walls etc. but i wouldn't necessarily encourage it. Also, as Nightfisher has said do NOT burn the green pressure treated wood in a fireplace or outdoor fire pit as it can release the toxic chemical and you could breathe it in. If you are going to use it for Halloween props etc. i don't see a big problem. It's safe otherwise. Good luck!
