Outdoor Playground Structure Materials (Pressure-Treated Wood, Metal, Composite) — outdoor safety profile
Low riskPlayground structure materials present chemical exposure from weathering and contact.
What is this product?
Playground structure materials present chemical exposure from weathering and contact. CCA (chromated copper arsenate) pressure-treated wood: banned for residential use in 2004 (EPA voluntary phase-out) but CCA playgrounds installed before 2004 remain in use — arsenic leaches to wood surface, transferring to hands. Replacement: ACQ (alkaline copper quat) and CA-B (copper azole) — copper-based, lower toxicity but corrosive to metal fasteners. Painted metal structures: pre-1978 paint may contain lead (children's hand contact, chalking paint). Composite/recycled plastic lumber: chemical additives (UV stabilizers, colorants) but very low exposure. Rubber coating on metal bars: may contain lead (CPSC recalls of rubber-coated playground equipment).
