The purpose of this protocol is to provide
guidelines for minimizing environmental contamination
and human exposure of oil-type wood preservatives
contained in pressure treated wood products. This
guideline will assist wood treaters in adopting treatment
and handling procedures to reduce migration of the pre-servative
from the wood and avoid shipment of treated
product that may otherwise have a tendency to lose pre-servative
from the wood surface.
These guidelines apply to wood products pres-sure
treated with oil-type preservative systems under
the jurisdiction of AWPA subcommittee P3. These
systems include the preservatives Standard P1/P13
(creosote), Standard P2 (creosote solution),Standard
P3(creosote -petroleum oil solution) and Standard P8
(oil-borne preservatives). The related standards which
are a part of the preservative systems listed, include
Standard P4 (petroleum oil for blending with creosote)
and Standard P9 (solvents for organic preservative sys-tems
used as carrier oils for the oil-borne preserva-tives).
These guidelines should be employed in con-junction
with a thorough understanding of the AWPA
Treatment Standards covering the treated wood com-modities
and preservatives specified. There are sub-stantial
differences in treatment methods for different
species of wood and preservative systems. Where these
guidelines may be in conflict with specific provisions of
the AWPA Treatment Standards, the Treatment Stan-dards
take precedence.
This protocol should only be used after reading
and thoroughly understanding the preservative product
label. A guideline shall not be used if it contradicts a
product label recommendation or if it is prohibited by
the product label.
These guidelines do not address the inherent
toxicological and environmental properties of the pre-servatives
themselves. These matters are under the ju-risdiction
of the United States Environmental Protection
Agency (US EPA).
