Why There Are No Refrigerators Without Prop 65 Warnings

What is Prop 65

Proposition 65 is a warning label for Californians about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm. Any product that is sold in California will have this label even at retailers outside of California.

The list contains naturally occurring and synthetic chemicals. It is updated yearly and there are currently 900 chemicals on the list in 2023.

Exposure Limit?

Technically this label is for “significant exposures” and the chemicals are not listed if “the exposure is low enough to pose no significant risk of cancer or is significantly below levels observed to cause birth defects or other reproductive harm.”

However, in reality, the exposure risk is not usually calculated and you will still see the label if the product contains only trace levels of the Prop 65 chemicals or even when the chemicals are enclosed within the product and there is no reasonable way to gain exposure to them.

Are Companies Adding This to Everything?

It does seem like there are companies that add this to all their products even though they might not contain a chemical on the list or even if the exposure is extremely minimal or exposure is not expected with regular use.

There is no penalty for providing an unnecessary warning, this part is frustrating to me.

You will often see the statement that a company “has elected to provide the Proposition 65 notice out of an abundance of caution in order to avoid the potential for liability.”

However when it comes to fridges and freezers, they do contain quite a few Prop 65 chemicals, they are not being overly cautious in declaring that Prop 65 chemicals are present. The real question and uncertainty around fridges and freezers comes down to whether that exposure is really large enough to be of concern, especially since the chemicals are largely enclosed within the appliance.

I’ll go over which Prop 65 chemicals are found in fridges and freezers and how to minimize your exposure.

Which Prop 65 Chemicals Can be Found in Fridges/Freezers:

1. Phthalates may be present in plastic components of appliances (specifically in flexible vinyl) according to the Prop 65 website. Electrical wiring is often coated in vinyl, and there may be other PVC parts.

2. Flame retardants may be present in plastic components of appliances according to the Prop 65 website. Fridges have foam insulation on all sides and this presumedly has flame retardants (which could be “tris”, a Prop 65 chemical). Electrical wiring and cords also can have flame retardants.

3. Antimony: Tamara Rubin has found that most appliance electrical cords will test positive for Antimony (as a component for added flame retardants). When she tests electrical cords of appliances, she normally finds the level in the range of 5,000 to 15,000 parts per million (ppm).

4. Arsenic: Tamara says she often finds trace Arsenic in black plastic handles of kitchen tools and appliances. She believes it is likely a contaminant of the black pigmentation. In one test she found extremely low levels of Arsenic in the black plastic handle of a kettle (3 +/- 1 ppm). This is safe, by any standard she explains, though it’s still a Prop 65 Chemical.

5. Cadmium: Tamara has found trace Cadmium (13 to 22 ppm) in borosilicate glass of a kettle. This is not unusual, says Tamara. There is no risk of exposure here in fridges.

6. Lead: can be found in plastic, electrical cords, nuts, painted parts, and more in appliances.

7. Other Proposition 65 chemicals may also be present in enclosed components of the appliance (such as printed circuit boards). During normal use, consumer exposure to these chemicals is expected to be negligible according to the Prop 65 website.

Minimize Exposure to Prop 65 Chemicals From Fridges

Since most of these chemicals are found in internal parts, and some are found in extremely low levels, the exposure is going to be minimal.

Flame retardants and phthalates do tend to leach out into household dust and so to minimize exposure to these chemicals, minimize your exposure to dust:

• Wash your hands before preparing food and before eating.
• Clean floors regularly, using a wet mop for hard surfaces and a HEPA vac for soft or hard surfaces. The HEPA component is important as it picks up these tiny contaminants (and is one of the best interventions you can make towards a healthy home).
• Wipe up dust regularly, using a damp cloth free of chemicals.

Fridge Brands With Prop 65 Warnings

Frigidaire, Samsung, Whirlpool, LG, GE, Magic Chef, Hisense, Haier, KitchenAid, Bosch, BLACK+DECKER, Kenmore, UNIQUE, Smeg, IKEA, and more, all have the warning.

I’ve not seen any fridge brands without the Prop 65 warning.

Lower Offgassing Fridge Brands

If you’re looking for fridges that are lower in initial offgassing, this post on appliances for the chemically sensitive has some ideas. These are all based on the experience of highly sensitive folks, not on empirical testing.
