Proposition 65 is an initiative originally approved by CA voters to address their growing concerns about exposure to toxic chemicals. It became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known by its original name of Proposition 65. Prop 65 requires the State of CA to publish a list of chemicals known to cause cancer or birth defects or other reproductive harm, etc. The chemicals include additives or ingredients in pesticides, common household products, food, drugs, dyes, or solvents. The program is administered by The Office of Environmental Health Hazard Assessment (OEHHA) which is part of the CA Environmental Protection Agency. Where required, warnings must be included with the product’s labeling.

REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) requires substances of very high concern (SVHC) that are imported into the EU in certain quantities to be registered with European Chemicals Agency (ECHA). A list of acceptable substances is maintained and any substances on that list do not require separate registration. REACH is a globally recognized initiative and most countries now have some level of a REACH program.

Mark indicates the product is produced by a company that limits product risks that can be reasonably foreseen. UL does not test each product in this case, instead they authorize the manufacturer to test their products and apply the UL listed mark themselves. However, UL does follow up with the manufacturer on a regular basis to make sure they are following correct procedures to test their products.
