Herein, what is ACQ timber?
Alkaline copper quaternary, usually abbreviated ACQ, is a type of water-based wood preservative product containing a soluble copper(II) complex and quaternary ammonium alkyl- or aryl-substituted compounds ("quats"). Thus the product was originally called ammoniacal copper/quaternary ammonium.
Similarly, is ACQ treated lumber toxic? ACQ has relatively low risks, based on its components of copper oxide and quaternary ammonium compounds. Results showed that ACQ-treated wood is essentially non-toxic by normal dermal and oral exposures.
