Pentachlorophenol Preservative Treatment

USAEHA TG 146.pdfDwg 13064136.pdf

The attached documents will clarify some misinformation circulated regarding wood preservative treatments.

Wood treated with pentachlorophenol is indicated by a "P" marking (Ref USAEHA TG 146 attached).  Pentachlorophenol is no longer used as a wood preservative and has been replaced by alternatives such as Copper-8-quinolinolate, zinc naphthenate, and copper naphthenate.

IAW Dwg 13064136 these alternative treatments that are currently authorized can be recognized by the following markings -

  • PA - Copper-8-quinolinolate
  • PB -  Zinc naphthenate
  • PC - Copper naphthenate

A PS Magazine Article (PS 677) as well as the DA Pam 742-1 22Nov2016 erroneously indicate that PA, PB & PC are  pentachlorophenol treated.
