INORGANIC ARSENICAL PRESSURE-TREATED WOOD
This lumber has been preserved by pressure-treatment with an EPA-registered pesticide containing inorganic arsenic to protect it
from insect attack and decay. Lumber treated with inorganic arsenic should be used only where such protection is important.
Inorganic arsenic penetrates deeply into and remains in the pressure-treated lumber for a long time. Exposure to inorganic arsenic
may present certain hazards. Therefore, the following precations should be taken both when handling the treated lumber and in determining
where to use or dispose of treated lumber.
Use Site Precautions
Lumber 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 lumber 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 food.
Do not use treated lumber for cutting-boards or counter-tops.
Only treated lumber that is visibly clean and free of surface residue should be used for patios, decks and walkways.
Do not use treated lumber for construction of those portions of beehives which may come in contact with the honey.
Treated lumber should not be used where it may come in direct or indirect contact with public drinking water, except for uses involving incidental
contact such as dock and bridges.
Dispose of treated lumber by ordinary trash collection or burial. TREATED LUMBER SHOULD NOT BE BURNED in open fires or in stoves, fireplaces or
residential boilers because toxic chemicals may be produced as a part of the smoke and ashes. Treated lumber 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 lumber. When sawing and matching treated lumber, wear a mask. Whenever possible, these
operations should be performed outdoors to avoid indoor accumulations or airborne sawdust from treated lumber.
When power-sawing and machining, wear goggles to protect eyes from flying particles.
After working with the lumber and before eating, drinking and use of tobacco products, wash exposed areas thoroughly.
If preservatives or sawdust accumulate on clothes, launder before reuse. Wash work clothes separately from other household clothing.
