Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The Proposition was intended by its authors to protect California citizens and the State's drinking water sources from chemicals known to cause cancer, birth defects or other reproductive harm, and to inform citizens about exposures to such chemicals. Under the statute, a person in the course of doing business cannot expose an individual to a chemical known to the state to cause cancer or reproductive toxicity without first giving a clear and reasonable warning to an individual. Proposition 65 requires the State of California to maintain and update a list of chemicals known to the state to cause cancer or reproductive toxicity
There have been some recent amendments made to the warning language requirements of Proposition 65 which are to be included on labels / packaging for products manufactured after 29th August 2018. XpressFill has reviewed the warnings and has taken the decision to include these warnings for all products sold in North America to ensure compliance with the latest requirements of this Californian law.
At the time of writing there are 973 chemicals on the Proposition 65 list, many without safe harbour exposure limits, the list
contains many naturally occurring and synthetic chemicals that are used in common household products, consumer goods,
drugs, dyes and even foods.
The warning means XpressFill is complying with the requirement of Proposition 65 to provide "clear and reasonable" warnings when one or more chemicals from the Proposition 65 list may be present, even in small trace amounts.
XpressFill has opted to label all of its products sold in North America using the language required by the State of California
as follows;
