Proposition 65 (formally titled "
The Safe Drinking Water and Toxic Enforcement Act of 1986") is a
California law passed by direct voter initiative in 1986 by a 63%-37% vote. Its goals are to protect drinking water sources from toxic substances that may cause
cancer and
birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.
Warning label
The following
warning language is standard on products sold in California if they contain chemicals on the Proposition 65 list and the amount of exposure caused by the product is not within defined safety limits.
WARNING: This product contains chemicals known to the State of California to cause
cancer and
birth defects or other reproductive harm.
The wording can be changed as necessary, so long as it communicates that the chemical in question is known to the state to cause cancer, or birth defects or other reproductive harm. For exposures from other sources, such as car exhaust in a parking garage, a standard sign might read: "This area contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm".
