California Prop 65

California leads the country in consumer protection. Columbia wants to provide a clear overview of California’s Proposition 65 Wood Dust Warning Requirements.

What Is California State Proposition 65?

According to the Office of Environmental Health Hazard Assessment, Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballet 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.

Proposition 65 requires the Governor to publish, at least annually, a list of chemicals known to the state to cause cancer or reproductive toxicity. On December 18, 2009, wood dust was added to the list of substances “known to the State of California to cause cancer.” Once a substance is listed, businesses have 12 months to comply with the warning requirements.

According to California Health and Safety Code Section 25249.6, as of December 18, 2010, no person in the course of doing business shall knowingly and intentionally expose an individual to wood dust without first providing a clear and reasonable warning. The warning requirement applies to any person employing ten or more employees who manufactures, produces, sells, distributes, or otherwise transfers a wood product into the stream of commerce in California.
