Califonia Warning 65

California Prop 65 Warning

×
For CA Residents Only.
California Proposition 65 Warning

Proposition 65, officially the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. The warnings are intended to help California consumers make informed decisions about their exposures to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more that 850 chemicals. In August 2016, OEHHA adopted new regulations, effective on August 30, 2018, which change the information required in Proposition 65 warnings.

• WARNING: Some cable, plastic, and metal products may contain chemicals known to the state of CA to cause cancer, birth defects, or other reproductive harm.
