I mean “I knew better than to burn it.” The bad grammar is due to lack of coffee, rather than long ago CCA exposure, I hope.
I built the substructure of a deck out of CCA (the stuff you come in daily contact with is done in redwood) back in ‘93, and knew better than to burn it, knew to wear a dust mask and long sleeves when cutting it, and so forth, too. But nobody’s born with that knowledge, you have to learn it from some source. For most do-it-yourselfers, the dangers of CCA were learned from the folks who sold them the wood the first time they used it.
I’m not sure whether this is constitutes a case for a Darwin Award or a case of slow-motion negligent homicide on the part of the staff of the lumberyard.
