The latest Fire Dept Service Announcement (FDSA) bulletin has raised the awarness of PFAS in C6 products. It said that transition should be to fire tested F3 products, nothing that several fire departments have recently sent out their F3 foams for specific sample testing for 1,4-dioxane and other chemicals. These departments have  taken the initiative to protect the public’s safety.

It noted that a Safety Data Sheet (SDS) for a foam product may state it does not contain PFOA or PFOS: “Those are just two of more than 12,000+ chemicals in the persistent, bio accumulative class. Although PFOA and PFOS are no longer produced in the US, they continue to appear in PFAS testing.

“Does the F3 foam contain other carcinogenic chemicals? There are clean F3 products available now that do not contain carcinogens.

“Your firefighting foam should have a fire test rating, i.e., UL 162, NFPA 18.”

The bulletin added that the US Department of Defense quietly released the new MilSpec for firefighting foam in early January 2023: “The updated Federal Aviation Administration (FAA) FAA CertAlert 139 followed on January 12, 2023. Sea-Tac Airport recently purchased National Foam’s Avio Green which they had tested in 2019. This product contains, formaldehyde, a known carcinogen and methanol, which is known to the State of California to cause birth defects or other reproductive harm.”
