Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law that applies to all companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels that are known to cause cancer, birth defects or other reproductive harm. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a “right-to-know” law. Businesses are required to provide warnings to comply with Proposition 65. These warnings are required to be in place for all products offered for sale in California.
There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including Automotive Performance products, and warnings can be seen posted throughout California in a variety of establishments such as hotels, restaurants, automobile dealerships/repair shops, and retail stores just to name a few.
To comply with the requirements of Proposition 65, this warning is present on all products sold by MPT.
