Handling & Disposal

ProWood® lumber and products are safe for people and animals, and earth friendly. ProWood is also a beautiful, safe option for planter boxes and garden beds. ProWood is a superior lumber product, but it's important to follow several tips when working with any treated wood, including ProWood lumber: 

ProWood Handling Recommendations:

  • Only use ProWood that is visibly clean and free of surface residue for patios, decks and walkways.
  • Do not burn ProWood.
  • Avoid prolonged inhalation of ProWood sawdust. When sawing, sanding or machining wood, wear a dust mask.
  • When power-sawing and machining ProWood, wear goggles.
  • Wear gloves.
  • At the end of each work session, clean up and dispose of all sawdust and construction debris, wash exposed areas of your body thoroughly, and wash your work clothes separately from other household clothing.

ProWood uses which are not recommended include:

  • Areas where ProWood may come into direct or indirect contact with drinking water, except incidental contact such as freshwater docks and bridges.
  • Areas where ProWood may become a component of food, animal feed or beehives.
  • Mulch for gardens or farming.

Things to remember when fastening ProWood MCA treated lumber:

  • There's no need for special fasteners. Use hot-dip galvanized or other fasteners as recommended by building codes.
  • Aluminum building products can be placed in direct contact with ProWood, however, aluminum contact is not recommended when ProWood products are immersed in water or are subject to frequent and prolonged wetting or other severe exposure conditions. In such cases, a moisture-resistant protective barrier should be placed between the aluminum products and ProWood.

Caring for ProWood is easy. Just keep in mind:

  • Mold growth may occur on any surface. While ProWood has been treated to help resist fungal growth, nothing can entirely prevent mold. Should mold growth occur, remove it from ProWood by simply washing it away with soap and water.

ProWood FR Handling Recommendations:

  • ProWood FR wood must be stored off the ground and protected from weather to prevent loss of the protective chemical treatment. Likewise, exposure during construction should be minimized. If some exposure occurs, the material must be allowed to dry to its original specification before being covered or exposed.
  • Do not burn fire-retardant treated wood.
  • Wear NIOSH N95 dust mask and goggles when cutting or sanding wood.
  • Wear gloves when working with wood.
  • Some fire-retardant treated wood chemicals may migrate from the treated wood into soil/water or may dislodge from the treated wood surface upon contact with skin. Wash exposed skin areas thoroughly.
  • All sawdust and construction debris should be cleaned up and disposed of after construction.
  • Wash work clothes separately from other household clothing before reuse.
  • Fire-retardant treated wood should not be used where it may come into direct or indirect contact with drinking water.
  • Do not use fire-retardant treated wood under circumstances where it may become a component of food, animal feed, or beehives.
  • Do not use fire-retardant treated wood as mulch.
  • Only fire-retardant treated wood that is visibly clean and free of surface residue should be used.

ProWood Disposal Recommendations

ProWood that is no longer usable — such as cutoffs, broken boards, sawdust or any product that has been taken out of use — may be disposed of in landfills. It should not be burned in open fires, in stoves, in fireplaces or in residential boilers.

ProWood FR Disposal Recommendations

  • Fire-retardant treated wood may be disposed of in landfills or burned in commercial or industrial incinerators or boilers in accordance with federal, state, and local regulations.
  • If you desire to apply a paint, stain, clear water repellent, or other finish to your fire-retardant treated wood, we recommend following the manufacturer’s instructions and label of the finishing product. Before you start, we recommend you apply the finishing product to a small exposed test area before completing the entire project to ensure it provides the intended result before proceeding.
  • Projects should be designed and installed in accordance with federal, state, and local building codes and ordinances governing construction in your area and in accordance with the National Design Specifications (NDS) and the Wood Handbook.
  • Mold growth can and does occur on the surface of many products, including untreated and fire-retardant treated wood, during prolonged surface exposure to excessive moisture. To remove mold from the treated wood surface, wood should be allowed to dry. Typically, mild soap and water can be used to remove remaining surface mold. For more information, visit
  • Use fire-retardant treated wood safely. Always read the label and product information before use.
