Burning"Pressure Treated" lumber scraps?
« on: September 27, 2018, 01:39:03 PM »

Seems like this must have been discussed before, so I apologize, I obviously suck at using the forum "search" feature, although I tried.

Anyway, we just finished building a deck on the house framed in pressure treated lumber.  We have quite a bit of odds & ends scrap.  Is this OK to burn in the outdoor furnace?  I live in a very secluded area.  Will it hurt my furnace?  (Or us?).

The gasses are toxic, creosote is toxic, ashes are toxic, and it's illegal.

Supposedly a teaspoon of ash contains enough arsenic, among other things, to kill a man.

If the labels say not to handle without gloves, it's probably nasty stuff.




I wonder how many people have burned this stuff and thrown the ashes in their garden.

 A fellow told me once that he had cows dying and couldn't figure out why. Found a place where someone had burned old treated fence posts years ago and the cows liked the salt and were licking the ground.

I throw dry plain lumber scraps in mine. But never anything treated.

Not to disagree with you about the dangers, and I'm sure it's still dangerous to breath, but I don't believe arsenic has been in used pressure treated lumber for quite some time now.   I know you shouldn't burn old PT wood for that reason.   These are brand new scraps.

I've probably thrown a scrap or two in the boiler here and there.  I didn't die and my boiler still works.

I'm not sure I'd make a habit of burning PT lumber, but a scrap here and there probably won't hurt.

You're right, some derivative of copper these days, depending on manufacturer. I wonder what the toxic ingredient is that gloves should be worn when handling.
