separately from other household clothing.
188.8.131.52 Pentachlorophenol Pressure-Treated Wood.
This wood has been preserved by pressure-treatment with an EPA-registered pesticide containing
pentachlorophenol to protect it from insect attack and decay. Wood treated with pentachlorophenol
should be used only where such protection is important.
Pentachlorophenol penetrates deeply into and remains in the pressure-treated wood for a long time.
Exposure to pentachlorophenol may present certain hazards. Therefore, the following precautions
should be taken both when handling the treated wood and in determining where to use and dispose
of the treated wood.
USE SITE PRECAUTIONS
Logs treated with pentachlorophenol should not be used for log homes.
Wood treated with pentachlorophenol should not be used where it will be in frequent or prolonged
contact with bare skin (for example, chairs and other outdoor furniture), unless an effective sealer
has been applied.
Pentachlorophenol-treated wood should not be used in residential, industrial or commercial interiors
except for laminated beams or building components which are in ground contact and are subject to
decay or insect infestation and where two coats of an appropriate sealer are applied. Sealers may be
applied at the installation site. Urethane, shellac, latex epoxy enamel and varnish are acceptable
sealers for pentachlorophenol-treated wood.
Wood treated with pentachlorophenol should not be used in the interiors of farm buildings where
there may be direct contact with domestic animals or livestock which may crib (bite) or lick the
In interiors of farm buildings where domestic animals or livestock are unlikely to crib (bite) or lick
the wood, pentachlorophenol-treated wood may be used for building components which are in
ground contact and are subject to decay or insect infestation and where two coats of an appropriate
sealer are applied. Sealers may be applied at the installation site.
