Changes Take Effect in August to California Proposition 65

(May, 2018) Significant changes take effect to California’s Proposition 65 on August 30, 2018. Prop 65 - officially known at the Safe Drinking Water and Toxic Enforcement Act - was originally passed in 1986 and requires California to publish a list of chemicals known to cause cancer or reproductive toxicity. Businesses with ten or more employees must provide warnings when they knowingly cause significant exposure to listed chemicals. 

Prop 65 does not ban or restrict the sale of chemicals on this list – they are intended to help Californians make informed decisions about their exposures to these chemicals. The current warnings do not identify the chemical or provide specific information about how a person may be exposed or ways to reduce or eliminate exposure.

The changes coming in August 2018 change the warnings in several ways, including: listing the name of at least one chemical that prompted the warning; use of a triangular yellow warning symbol; clarifying the roles and responsibilities of manufacturers and retailers in providing warnings; and adding new, tailored warnings that provide more specific information.
