Consumer information approved by the U.S.
Environmental Protection Agency For Inorganic
Arsenical Pressure Treated Wood.
dec WHENEVER YOU BUILD WITH
TREATED WOOD PRODUCTS FROM
GEORGIA-PACIFIC, BUILD CORRECTLY.
Whatever you build with Georgia-Pacific treated wood prod-
ucts should last a long time. So, it makes good sense to build
in a craftsmanlike manner. Here are some helpful tips to make
your job easier and look better.
CONSUMER INFORMATION
This wood has been preserved by pressure-treatment
with an EPA-registered pesticide containing inorganic arsenic
to protect it from insect attack and decay. Wood treated with
inorganic arsenic should be used only where such protection
is important.
Inorganic arsenic penetrates deeply into and remains in
the pressure-treated wood for a long time. Exposure to inorganic
arsenic may present certain hazards. Therefore, the following pre-
cautions should be taken both when handling the treated wood
and in determining where to use or dispose of the treated wood.
USE GALVANIZED FASTENERS.
Use galvanized or stainless nails, screws, or bolts
when working with pressure treated wood. These types of
fasteners are corrosion-resistant and should minimize rust
stains on your project.
USE SITE PRECAUTIONS
Wood pressure-treated with waterborne arsenical
preservatives may be used inside residences as long as all
sawdust and construction debris are cleaned up and disposed
of after construction. Do not use treated wood under circum-
stances where the preservatives may become a component of
food or animal feed. Examples of such sites would be struc-
tures or containers for storing silage food.
Do not use treated wood for cutting-boards or countertops.
Only treated wood that is visibly clean and free of surface
residue should be used for patios, decks, and walkways.
Do not use treated wood for construction of those portions
of beehives which may come into contact with the honey.
Treated wood should not be used with public drinking
water, except for uses involving incidental contact such as
docks and bridges.
NAIL BARK SIDE UP.
Always nail boards bark side up
(annual rings arc upward) to
reduce cupping. Nail thin
boards to thicker boards to
maintain structural integrity.
Treated Lumber
DRILL PILOT HOLES.
Especially when nailing near the edge or end
of a board, it’s a good idea to drill pilot holes
for your fasteners.
BUTT BOARDS TIGHTLY.
Butt decking boards together firmly. As drying occurs,
some shrinkage can be expected.
HANDLING PRECAUTIONS
Dispose of treated wood by ordinary trash collection or
burial. Treated wood should not be burned in open fires or in
stoves, fireplaces, or residential boilers because toxic chemicals
may be produced as part of the smoke and ashes. Treated
wood from commercial or industrial use (e.g., construction sites)
may be burned only in commercial or industrial incinerators or
boilers in accordance with state and Federal regulations.
Avoid frequent or prolonged inhalation of sawdust from
treated wood, When sawing and machining treated wood, wear
a dust mask. Whenever possible, these operations should be
performed outdoors to avoid indoor accumulations of airborne
sawdust from treated wood.
When powersawing and machining, wear goggles to protect
eyes from flying particles. Gloves can provide extra protection
against splinters and freshly treated wet wood. Allow freshly treat-
ed wet wood to dry thoroughly before handling. Follow good per-
sonal hygiene practices in the shop and on the job. After working
with the wood, and before eating, drinking, and use of tobacco
products, wash exposed areas thoroughly. If preservatives or
sawdust accumulates on clothes, launder before reuse. Wash
work clothes separately from other household clothing.
APPLY A
WEATHER-RESISTANT FINISHÉ
Any exposed wood, pressure treated or not, should be pro-
tected from the weather. Application of a finish coat of clear
water repellent or semi-transparent stain will help to minimize
warping, checking, or splitting. The finish coat should be
applied to pressure treated wood as soon as it is dry to the
touch, and immediately to untreated wood. (Option: stain or
water repellent may be applied when the wood is surface dry.)
