This wood has been preserved by pressure-treatment with an EPA-registered pesticide containing in-
organic 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 precautions
should be taken both when handling the treated wood and in determining where to use or dispose of
the treatedwood.
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 circumstances where the preservative may become a component of
food or animal feed. Examples of such sites would be structures or containers for storing silage or
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 where it may come into direct or indirect contact with public drink-
ing water, except for uses involving incidental contact such as docks and bridges.
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 inhalation of sawdust from treated wood. When sawing and
machining treated wood, wear a respirator. Whenever possible, these operations should be per-
formed outdoors to avoid indoor accumulations of airborne sawdust from treated wood. Wear work
coveralls rather than street clothes.
When power-sawing and machining, wear goggles to protect eyes from flying particles.
