Yeah, it MAY cause a certain problem. Take precautions.

Having worked with CCA (which is not made any more due to the
threat of junk lawsuits and not because the EPA or anyone else
recommended the production be halted) for the last 30 years, I
believe that I have a certain knowledge about its use. I can
guarantee that I have been exposed to more CCA than ANYBODY
that is exposed to casual contact. I have had months where I
did nothing but saw and install PT lumber on huge decks, pool
decks, etc. I did not (nor was it recommended at the time)
use any dust masks, gloves, etc. I am fine. Just had a
checkup when I turned 52 and everything is great (except for
the getting old part).

This is one of those overblown, paranoid delusions that make
some people a lot of money and many people very afraid.

Take precautions and don't worry about it. The newer stuff is
supposed to be less dangerous, so you can probably eat it.

NOTE: I do not condone, nor recommend eating ACQ treated
lumber. It tastes terrible.

well some people chain smoke for a lifetime and die at 90 of old age,
while others with less exposure get emphsema, heart disease, cancer,
and die young from smoking./

one persons report does not determine safety of anything.

In 1985 my mom wanted a raised bed for growing vegetables. after
looking into PT I built it frome reguar wood, concerned of PT chemical
leaching into food. It was considered PERFECTLY SAFE at that time. by
1995 PT was out for growing around veggies.

I've been around even longer than Robert and I don't recall ever
hearing a recommendation for _other than_ treated lumber for garden
beds. That said, of course, who knows how many millions of old (or
even new) creosote-treated ties have been used for the very same
purpose? Or, of course, any of the treated lumber (pressure or not)
has also been used whether recommended or not by millions for garden
beds I'm sure.

Can you find even one actual citation of a confirmed illness or
serious complications attributable to CCA? In several previous
discussion like this no one has yet provided that firm confirmation of
there being a real problem. With all the carpenters and other
construction workers like Robert who have handled the stuff for years,
it would seem the epidemiological evidence would be quite readily
available if it were really a hazard, yet as near as I can tell, it
doesn't exist. That pretty much tells me the "problem" isn't a real
problem.

Cigarette smoke, otoh, _does_ have a strong correlation w/ morbidity
statistics that is irrefutable and widely available. "Carcinogenic",
otoh, in the sense given by EPA tests on lab rats wherein they're
exposed to direct contact w/ the substance at dosage levels that are
simply unobtainable in real world scenarios isn't particularly useful
for judging actual risk -- in fact, it leads to the ridiculousness one
sees in CA where virtually everything is labelled as a risk of some
sort.

All I"m asking for is a little more perspective on actual vis a vis
perceived risks here. If you can find the epidemiology data, I'll be
right in line...
