California’s Office of Environmental Health Hazard Assessment (Oehha) adopted amendments in September 2016 on how “clear and reasonable warning” should be provided under Proposition 65. Among the changes, this will require the warnings to contain the name of at least one substance for which notice is being provided under the law. A pictogram – an exclamation mark inside an equilateral triangle – must also be included. The new Prop 65 warning requirements take effect from 30 August 2018. In the meanwhile, businesses may either comply with the new provisions or with the law prior to its amendment.
