Splinters piercing the skin are a more questionable means of entry. Ingestion occurs most frequently when contaminated hands are put into one’s mouth or contaminated hands are used on food that is being eaten. Toxins may enter the body through the skin or by ingestion. Playground structures and other home-based structures built from pressure-treated wood are most likely to be of the CCA type. Creosote and PCP are the most acutely toxic. The least acutely toxic are Copper Napthenate, Zinc Napthenate, Copper-8, Niedox-10, and Arsenic. Other wood preserving substances used are Copper Napthenate, Zinc Napthenate, Copper-3, Niedox-10 (contains Boric Acid), and Ethylene Glycol. CCA contains Arsenic Pentoxide, Copper Oxide, Chromium (III) Oxide or different related compounds. The most commonly used substances that are or may have been used for playground structures are Pentachlorophenol (PCP), Creosote, Arsenic and related compounds, and CCA.

If there are still concerns about using pressure-treated wood, alternatives to consider include: cedar, redwood, painted metal, or plastic.

If the pressure-treated wood cracks to expose the interior, but the wood is still structurally sound, apply a double coat of non-toxic, non-slippery wood sealant to the affected area.

Do not place food, drink or paper products used for eating on preserved or pressure-treated wood products that have not been properly sealed.For all wood treatment substances, including arsenic, double coat the pressure-treated wood with an appropriate non-toxic, non-slippery wood sealant, such as an oil-based stain.Adults should use special precautions in handling pressure-treated wood when constructing the playground or play structures. Children should not be exposed to preserved or pressure-treated wood or its dust during construction.The following precautions, if followed, should significantly reduce or eliminate exposures to arsenic residues from arsenic-treated wood. The MSDS is a summary of properties, health effects, protective precautions used to reduce exposure, and spill cleanup procedures. The Material Safety Data Sheet (MSDS) for the wood treatment substance can be obtained from the supplier. Use a supplier that guarantees this standard. Arsenic-treated wood (the least acutely toxic) should meet the American Wood Preservers' Association commodity standard. Do not use wood treated with creosote or pentachlorophenol (PCP).
