About Prop 65:

Companies doing business or selling products in California are required to provide "clear and reasonable" warnings before knowingly exposing Californians to certain chemicals the state has identified as hazardous. This warning can be given in several ways, including labeling a consumer product, posting signs at the workplace, distributing notices at a rental housing complex or publishing notices in a newspaper.

The California Office of Environmental Health Hazard Assessment (part of California EPA) publishes the official Prop 65 list of chemicals known by the state to cause cancer, birth defects or other reproductive hazards. The list contains a wide range of naturally occurring and synthetic chemicals.

A business must use knowledge of its business operations and the chemicals it uses to review the Proposition 65 list to determine whether its operations or products are likely to expose people in California to any listed chemicals. Depending on the level of exposure, the business may be required to provide a warning for those exposures.



You Probably Have Questions - We Do Too!

Unfortunately, there are very few answers. ComplianceSigns contacted the OEHAA (Prop 65 Office) and we were directed not to give any advice on whether a sign is correct for a particular location or application. Other questions with no clear answer include: What is the correct way to describe exposure sources; How many signs are required; and Who enforces the new rules. You must make the decision on sign necessity and content based on your knowledge of your business, the types of chemicals that are present and the approach you take to comply with the new Prop 65 regulations.

We always try to be more helpful than that to our customers, so we assembled this list of resources that may help you with your Prop 65 questions:
