Compliance Resources for Rapidly Approaching Deadline for New Proposition 65 Warnings

July 17, 2018 - Kirsten Wallerstedt

As of 30 August 2018, all businesses affected by California’s Proposition 65 must have new labels, signs, or other warnings in place for any exposure to a listed substance which occurs in California.

Compliance with Proposition 65 is especially troubling to businesses, since most enforcement is done through “citizen” enforcers who may sue a company for alleged violations of the law. Proposition 65 requires businesses to provide a “clear and reasonable” warning prior to exposing any individual to a Proposition 65-listed substance above save harbor levels.

To help comply by this deadline, the state’s Office of Health Hazard Assessment (OEHHA) has released a new compilation of available resources:

It is vital for businesses to understand that the new regulations do not determine when a warning is required. Rather, the new regulations provide guidance for businesses on how to meet the standard of providing a “clear and reasonable” warning. The new regulatory text makes significant changes to Article 6 of the Proposition 65 regulations, which sets out compliant ways that businesses may provide a clear and reasonable warning.
