Wolmanized® Residential Outdoor® Wood: Use & Handling


Common Sense Safety Precautions
The following precautions should be taken both when handling the preserved wood and in determining where to use and dispose of it.  Many of these precautions also apply to untreated wood and other building materials.

Use Site Precautions

•  All sawdust and construction debris should be cleaned up and disposed of after
•  Do not use treated wood under circumstances where the preservative may
    become a component of food or animal feed.  Examples are mulch from recycled
    treated wood, cutting boards, counter tops, animal bedding, and structures
    or containers for storing animal feed or human food.
•  Only treated wood that is visibly clean and free of surface residue should be
    used where contact is likely.
•  Do not use treated wood for construction of those portions of beehives which
    may come into contact with honey.
•  Treated wood should not be used where it may come into direct or indirect
    contact with drinking water, except for uses involving incidental contact such
    as docks or bridges.

Handling Precautions
•  Dispose of treated wood by ordinary trash collection.  TREATED WOOD SHOULD
    NOT BE BURNED in open fires or in stoves, fireplaces or residential boilers
    because toxic substances may be produced as part of the smoke and ashes.
    Treated wood from commercial or industrial use (e.g., construction sites) may
    be disposed of by complying with local landfill rules or burned in commercial or
    industrial incinerators or boilers when done in accordance with state and
    federal regulations.
•  Avoid frequent or prolonged inhalation of sawdust from wood, treated or
    untreated. When sawing, sanding, and machining wood, wear a dust mask.
    Whenever possible, these operations should be performed outdoors to avoid
    indoor accumulations or airborne sawdust.
•  When power-sawing and machining, wear goggles to protect eyes from flying
•  Wear gloves when working with wood.  Use proper techniques when lifting.
    After working with wood, and before eating, drinking, toileting, and use of
    tobacco products, wash exposed areas thoroughly.
•  Because preservatives or sawdust may accumulate on clothes, they should be
    laundered before reuse. Wash work clothes separately from other household

Note:  The active ingredients in copper azole are copper, tebuconazole and propiconazole.
