Proposition 65 Warning (Prop 65) refers to a label required by California’s Safe Drinking Water and Toxic Enforcement Act of 1986.
It’s meant to inform Californians about exposure to chemicals that may cause:
- Cancer
- Birth defects
- Other reproductive harm
Why You Might See a Prop 65 Warning:
A product gets a Prop 65 warning if it contains even trace amounts of chemicals listed by the state of California as potentially harmful.
These chemicals can be found in:
- Plastic products
- Electronics
- Furniture
- Food & supplements
- Household items
- Personal care products
Example of a Prop 65 Warning:
⚠️ WARNING: This product can expose you to chemicals including [chemical name], which is known to the State of California to cause cancer or birth defects or other reproductive harm.
Common Chemicals on the Prop 65 List:
- Lead
- BPA
- Formaldehyde
- Acrylamide (found in some cooked foods)
- Phthalates (used in plastics)
Is It Dangerous?
Not necessarily. A Prop 65 warning:
- Does not mean the product is unsafe.
- Does mean the company is complying with California law.
- May reflect very low exposure levels, sometimes far below federal safety limits.
Should You Be Concerned?
- If you’re pregnant, nursing, or have small children, it may be worth checking what the specific chemical is.
- If you live outside California, you may still see the warning on products sold nationwide due to uniform labeling.
Why Outdoor Furniture & Firepits Have Prop 65 Warnings
1. Materials and Coatings
- Metal furniture may be coated with powder coatings, paints, or finishes containing:
- Lead or cadmium
- Chromium (hexavalent) – linked to cancer
- Plastic or synthetic wicker can contain phthalates, which may affect reproduction.
- Cushions or foams may contain:
- Flame retardants
- Formaldehyde
- Polyurethane foam chemicals
2. Combustion By-products (Firepits)
- Burning wood, propane, or natural gas releases:
- Carbon monoxide
- Soot (particulate matter)
- Benzene
- PAHs (polycyclic aromatic hydrocarbons) – linked to cancer
- Even natural wood smoke contains Prop 65-listed chemicals.
3. Welding or Manufacturing Residues
- Metal furniture or firepits made using welding or soldering may carry a warning due to residual nickel, lead, or other heavy metals.
How to Reduce Risk:
- Use firepits in well-ventilated outdoor areas.
- Avoid prolonged exposure to fumes or smoke.
- Wipe down new furniture before use.
- Cover cushions when not in use to prevent chemical breakdown from UV.
- Use non-toxic, eco-friendly cushions if possible.
