CPSC Flame Retardant Petition

Beginning in 2011, our “big idea” project initiated a paradigm shift towards managing  harmful chemicals by class rather than one at a time. In 2017, the Consumer Product Safety Commission (CPSC) accepted our joint petition to ban furniture, children’s products, electronics casings, and mattresses that contain any member of the chemical class of additive non-polymeric organohalogen flame retardants.

The CPSC petition calls for the phasing out of furniture, bedding, children's products, and electronics containing organohalogen flame retardants.

The problem: harmful flame retardants in household products

Among the tens of thousands of synthetic chemicals, the class of organohalogens (in which carbon is bonded to bromine, chlorine, or fluorine) is uniquely problematic. These chemicals are often toxic, persistent, and bioaccumulative in our bodies and the environment. Many are similar in structure or even identical to banned chemicals such as DDT, Mirex, and PCBs. All 29 chemicals globally banned as Persistent Organic Pollutants under the Stockholm Convention are organohalogens. 

One major use of organohalogens is as flame retardants added to furniture, children’s products, electronics, and building insulation to meet flammability standards. They often don’t improve fire safety and can harm our health. You can watch a short video and learn more here.

Biomonitoring studies find organohalogen flame retardants in the bodies of nearly all Americans tested, with the highest levels in young children. These chemicals cause reproductive, immune, and neurological problems and cancer in animal studies. In humans exposure is associated with reduced IQ and fertility, birth defects, and hormonal changes. If we can reduce human exposure to this class of toxic chemicals, we can prevent health problems.

The good news is that the use of flame retardants can be greatly reduced without impacting fire safety. Safer substitute chemicals and technologies are available.

Our 2015 Science-Based Petition to the CPSC

Given the toxicity and persistence of organohalogen flame retardants, we collaborated with Earthjustice, beginning in 2011, to draft a petition to the CPSC to ban the use of products containing these chemicals. In 2015, a coalition of medical, firefighter, consumer, and scientific groups joined us and asked the CPSC to adopt rules under the Federal Hazardous Substances Act to protect consumers from organohalogen flame retardants in four categories of household products:

  • residential furniture
  • children’s products
  • the outer casings of electronics
  • any mattress or mattress pad

Read the full text of the petition and supporting statements.

This petition puts forth the class concept, a new approach for addressing harmful chemicals by class rather than one-by-one. This approach helps prevent regrettable substitutions, where phased out chemicals are replaced with chemical cousins with similarly harmful properties.

The decision

After years of coordinated effort by our Institute and partners, the CPSC granted our petition in September 2017. A precedent-setting notice was published in the Federal Register warning manufacturers, consumers, and especially pregnant women and children against using the entire class of organohalogen flame retardants in children's products, furniture, mattresses, and electronics cases.

The National Academy of Sciences report

To implement this decision, the National Academy of Sciences (NAS) assembled a guidance committee of experts. In May of 2019 this committee issued a report endorsing a class-based approach for regulating halogenated flame retardants. This report reaffirms the usefulness of the class concept and the problem of "regrettable substitution."

This report:

  • notes that assessing chemicals as a class would make regulatory hazard and risk assessment much more efficient.
  • states that the individual assessments of hundreds of chemicals is unrealistic. “The only possible practical approach for a set of chemicals as large as the OFRs is a class approach."
  • defines 14 subclasses based on chemistry (6 subclasses) and predicted health impact (8 subclasses).

Next steps for the petition

Potential next steps include: 

  • If the CPSC agrees to follow the NAS recommendations, they will do in-depth literature studies of the subclass members.
  • The CPSC forms a Chronic Hazard Advisory Panel and charges them with carrying out the class-based hazard assessment.

Women with higher levels of flame retardants in their blood: (i) took significantly longer to get pregnant; (ii) had babies with lower birth weight; and (iii) had lower thyroid hormone levels during pregnancy.

By the time children were 5 to 7 years old, their mother’s flame retardant exposure during pregnancy was associated with lower IQ (a decrease by 6 points on average), attention problems, and impaired fine motor coordination, …

The available data on organohalogen flame retardants indicates a high likelihood that other yet unstudied members of this class of chemicals are also endocrine disruptors, which means they can impair normal cell development, and thus cause substantial personal injury or substantial illness.
