Most treated wood we buy today has been pressurized/treated with barite, rather than the older method of using a copper and arsenic suspension. While there's some risk of contamination in handling the old type of treated wood, the barite treated product has almost no risk, IMHO.
But, when cutting either type of product, a respirator, or mask, should be worn. If you're only making a few cuts, and there's adequate ventilation, then you can probably do without the mask and not be at any risk.
You can tell how it's been treated by the color: copper/arsenic has a greenish tinge, whereas the barite treatment imparts a reddish tone. |
