California Proposition 65 Warning

Last updated: August 25, 2026

What Is Proposition 65

Proposition 65, formally the Safe Drinking Water and Toxic Enforcement Act of 1986, is a California law that requires businesses to give a “clear and reasonable warning” before knowingly exposing anyone in California to chemicals the State has listed as causing cancer, birth defects, or other reproductive harm. The list is maintained by California’s Office of Environmental Health Hazard Assessment (OEHHA) and now contains roughly 900 substances, updated at least annually.

Proposition 65 is a disclosure law, not a product safety standard. It does not ban any chemical or product, and its warning thresholds are deliberately conservative — often set far below the levels at which any harm has been observed, and far below federal or international limits. It applies to companies selling into California regardless of where they are located.

Why You May See a Warning

Fitness equipment is assembled from rubber, vinyl, foam, textiles, plated steel, and electronic components. Listed chemicals can be present in trace amounts in these materials or in the manufacturing processes used to produce them. Common reasons a warning may appear on FITMAX products include:

Phthalates such as DEHP and DINP — used as plasticizers in PVC and synthetic rubber, so they may be present in machine grips, handle sleeves, jump ropes, resistance tubing, rubber-coated dumbbells and plates, and gym flooring or protective mats;
Lead and lead compounds — may occur in trace amounts in welding consumables, brass and bronze bushings, some alloys, and painted or powder-coated metal surfaces on frames, racks, and weight stacks;
Nickel and nickel compounds — present in stainless and chrome-plated hardware, guide rods, adjustment pins, and chrome barbell finishes;
Chemicals in foam padding and synthetic upholstery — bench pads, seat cushions, roller pads, and PU or PVC “leatherette” covers may contain listed residues from foaming agents, flame retardants, or coatings;
Di-isononyl phthalate and related compounds — in printed decals, vinyl wraps, cable coatings, and power cords on electronic cardio equipment;
Carbon black and processing residues — associated with rubber compounding used in mats, tires on rowers and bikes, and bumper plates.

Because supply chains and formulations change, and because testing every component to Proposition 65 thresholds is not always practical, manufacturers frequently apply a warning as a precaution rather than as a statement that a specific exposure has been measured.

Standard Warning Language

Where a warning is required, FITMAX products, packaging, or listings carry the standard California language in substantially the following form:

⚠️ WARNING: This product can expose you to chemicals including DEHP, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

The chemical named in the warning varies by product and material. Depending on the item you may instead see lead, nickel, di-isononyl phthalate, or another listed substance, and the warning may reference cancer only, reproductive harm only, or both. The specific wording that applies to your purchase is the wording shown on that product’s page, label, packaging, or owner’s manual.

What This Means for You

A Proposition 65 warning does not mean the product violates any safety standard or legal limit, and it does not mean the product is defective or unsafe for its intended use. FITMAX equipment is manufactured to applicable United States and international product-safety requirements, and the presence of a warning is not an admission that any exposure has occurred or that any harm will result.

The warning exists because California requires disclosure at exposure levels far more conservative than other jurisdictions. Products sold outside California often contain the same materials without any warning, simply because no other state imposes the same requirement. Treat the warning as information, not as a hazard rating.

Reducing Potential Exposure

If you would like to minimize contact with trace chemicals, these ordinary precautions are sufficient for normal use:

Use the equipment as designed and as documented in the owner’s manual;
Wash your hands after handling rubber-coated weights, grips, mats, and plated hardware, and before eating or drinking;
Do not allow children to mouth, chew, or play with grips, tubing, mats, cable coatings, or small hardware;
Unbox and air out new rubber mats and rubber-coated products in a well-ventilated space for a few days; a rubber odor is normal and fades;
Ventilate home gyms, garages, and basements, especially in warm weather when rubber flooring off-gasses more;
Wipe down pads and upholstery with a mild cleaner rather than solvents, which can degrade coatings;
Wear gloves if you have a known nickel sensitivity or are handling chrome and plated components for extended periods;
Do not cut, sand, grind, burn, or weld any component — these processes can generate dust or fumes that normal use does not.
