[*]Avoid using lumber treated with creosote or PCP in any home construction or landscaping project.
[*]Don’t use treated lumber for any indoor home construction project. Wood treatment chemicals are too toxic for interior uses.
[*]Seal decks that are constructed with treated lumber with an oil-based sealer every two years. This is consistent with the wood manufacturer's recommendations for maintenance of CCA-treated wood. Proper sealants will keep the wood from cracking and splintering while reducing the risk of exposure to CCA residues.
[*]Do not allow children to play under decks made with treated lumber. Ensure that children playing on or around structures made with treated lumber wash their hands before eating. Pets that regularly sleep or live under decks could be exposed to arsenic and may carry it into your home.
[*]Sawing or sanding treated wood is hazardous and requires special precautions. Perform the work outdoors on a dropcloth so the sawdust can be collected and discarded. Wear a dust mask if there is frequent or prolonged exposure to sawdust. Wash hands and clothing immediately after completing the work.
[*]Do not use treated wood for countertops, cutting boards, picnic tables, beehives or for other applications where treatment chemicals may come into contact with food.
[*]Never burn treated wood. Burning releases toxic fumes into the air and has been associated with serious arsenic poisoning.
