On 30 Aug. 2016, California’s Office of Environmental Health Hazard Assessment has adopted amendments to how "clear and reasonable warning" is provided under Proposition 65.

There are following changes in the amendment:

1. The update will require the warnings to contain the name of at least one substance for which notice is being provided under the law.

2. A pictogram – an exclamation mark within an equilateral triangle – must also be included.

Warning statements under the new law shall also direct consumers to the new Prop 65 website (https://www.p65warnings.ca.gov/)

The regulation will be operative on 30 Aug. 2018. In the interim, businesses may comply with the regulation in effect on 30 Aug. 2016, or the provisions of the new regulation. C&K Testing advises businesses to deal with due care.
