California Prop #65 (OEHHA Regulation)

New Office of Environmental Health Hazard Assessment (OEHHA) regulations, adopted in August 2016 and in effect as of August 30, 2018, change safe harbor warnings in compliance with the law in several important ways.For example, the new warnings for consumer products will say the product “can expose you to” a Proposition 65 chemical rather than saying the product “contains” the chemical. They will also include:

  • The name of at least one listed chemical that prompted the warning
  • The Internet address for OEHHA’s new Proposition 65 warnings website,, which includes additional information on the health effects of listed chemicals and ways to reduce or eliminate exposure to them
  • A triangular yellow warning symbol on most warnings


How Do the New Warnings Compare to the Current Warnings?

A typical current Proposition 65 warning states, “WARNING: This product contains a chemical known to the State of California to cause cancer.” A sample new warning would look like this: “ WARNING​: This product can expose you to chemicals including arsenic, which is known to the State of California to cause cancer.
