Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. A number of chemicals that have been used either as flame retardants, or to enhance the flame-retardant properties of other chemicals, are on the Proposition 65 list.
