DOD and FAA Approve Use of a PFAS-Free Fire Suppressant

This September, the Department of Defense (DOD) announced the approval of the first PFAS-free foam for firefighting activities at military installations.  The approval is an important step in phasing out the use of PFAS-containing aqueous film forming foams (AFFFs), which are used to extinguish liquid fires.

The day after the foam received DOD approval, the Federal Aviation Administration (FAA) notified airports that they could use it.  FAA is not currently requiring exclusive use of the PFAS-free foam, however.

The transition away from PFAS-containing foams is required by section 322 of the 2020 National Defense Authorization Act.  Among other deadlines, the act prohibits DOD from purchasing fire-fighting foams containing more than 1 part per billion PFAS beginning October 1, 2023.

DOD issued a performance specification for PFAS-free (also known as fluorine-free) foams in January of this year.  According to DOD’s announcement, several other fluorine-free foams are currently being tested for conformance with the specifications.
