Welcome to the Proposition 65 Warnings Website

The California Office of Environmental Health Hazard Assessment established this website to provide the public with information on chemicals, products and places often associated with Proposition 65 warnings.  These warnings inform Californians about their exposures to chemicals that cause cancer, birth defects or other reproductive harm. 

Visiting this website regularly will help you learn about these chemicals and how you can reduce your exposure to them.  We will be adding new information frequently.
