Hi, I'm hoping to get some clarification. I'm making a diy firewood storage using cinder/Besser blocks and wood . The only suitable size and price I've found at hardware is fence pailings, they are perfect however are treated with H3 arson ,the guy working there gave me this info and assures me it's fine to have my firewood against this as it will not leak into my firewood. However he then tells me to make sure I wear gloves while handling the fence pailing. I haven't bought them yet as I want to be certain. Would any one know this ..please and thankyou.
