U.N. Expert Committee Recommends Global Elimination of Toxic Chemical Harming Health of Firefighters: PFHXs, Used as Substitute for Banned PFOS and PFOA, Recommended for Global Ban

A U.N. expert committee decided unanimously to recommend a complete global elimination for another toxic fluorinated "forever chemical." Fluorinated chemicals are widespread pollutants threatening drinking water sources, public health, and the occupational health of firefighters. They do not break down in the environment and accumulate in the bodies of wildlife and people. They are used in a wide variety of products, including firefighting foam, waterproofing of textiles, and food packaging, as well as other industrial and consumer applications.

The Committee recommended the global elimination of PFHxS and 147 related substances. PFHxS is a toxic chemical that was used by the fluorine industry as a replacement for two other fluorinated compounds, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Fluorinated substances, also known as PFAS (per- and polyfluoroalkyl substances), are at the center of a current wave of lawsuits since they have been found in high levels in ground- and drinking water near industrial facilities, airports and military bases. The Committee warned against repeating the mistake of using other PFAS, by noting that "a transition to the use of short-chain per- and polyfluoroalkyl substances (PFASs) for dispersive applications, such as fire-fighting foams, is not a suitable option from an environmental and human health point of view." In 2009, PFOS was listed under the Stockholm Convention for global elimination and earlier in 2019, the Conference of the Parties of the Stockholm Convention listed PFOA for global elimination.

Before the meeting, IPEN released a comprehensive report featuring eminent, independent experts across the fire engineering and fire safety sectors that presents unequivocal evidence from recent studies that firefighters using aqueous film-forming foams (AFFF) have unacceptably elevated blood levels of both PFHxS and PFOS. Earlier IPEN reports describe fluorine-free firefighting foam alternatives that can replace all uses of toxic fluorinated firefighting foams.

"This recommendation will help protect firefighters all around the world from exposure to toxic chemicals that cause cancer. Firefighters have some of the highest rates of cancers and other diseases associated with occupational exposures to toxic chemicals," said Commander Mick Tisbury, Vice President of the United Firefighters Union of Australia, and Commander of the Melbourne Metropolitan Fire Brigade (MFB).

In September, the U.N. Human Rights Council passed a resolution "highlighting the global crisis confronting workers exposed to toxic substances" and calling upon governments and industry to meet their obligations under international human rights mechanisms to protect the health and safety of workers.

IPEN partner Alaska Community Action on Toxics (ACAT) recently published a report showing widespread contamination of drinking water in communities around Alaska caused by dispersive uses of PFAS-based firefighting foam.

"PFAS contamination of drinking water is threatening the health of people in many of our communities in Alaska and of millions of people around the world. The fluorine industry has denied and deceived the public for decades. It is time that they are held accountable and stop producing these dangerous chemicals," stated Pamela Miller, IPEN Co-Chair and Executive Director of Alaska Community Action on Toxics.

The Committee also highlighted that this large class of chemicals can be dealt with using a grouping approach, which has been found to be an important method to reduce the likelihood of substituting one toxic chemical with another.

"There is increasing evidence for concern about the whole class of fluorinated chemicals, and the industry should stop replacing one bad chemical with another closely related bad chemical. Knowingly pursuing this approach is just cynical self-interest by the industry that damages human health," said Dr. Sara Brosche,
