[QUOTE="jigngrub, post: 217686, member: 6657"] They banned the arsenic formula PT because a very few people were having reactions to it from walking on it in their bare feet when it was installed exposed for decking and such. It is still approved for marine use because it is covered with glue and carpet, vinyl, or encapsulated in between layers of aluminum like transoms and such. The new ACQ PT lumber is still toxic (it still has to kill the bug that tries to eat it), but just not [b]as[/b] toxic as the old CCA formula. The new ACQ formula has much higher levels of copper in it and that's why it corrodes aluminum. The new ACQ PT wood still shouldn't be burned and scraps may be considered toxic waste in some areas.
