Abstract:

The objective of the work described in this report was to identify and experimentally test functional additives for per- and polyfluoroalkyl substance (PFAS)-free fire-fighting foams in order to improve the physical properties and fire-fighting capabilities of the foam. PFAS are a common ingredient in aqueous filmforming foams (AFFF) due to their oleophobic properties and stability at elevated temperatures, but are being banned due to both environmental andhealth concerns. The National Defense Authorization Act (NDAA) has ordered the phaseout of PFAS containing AFFF at U.S military facilities by 2024,however, none of the currently available PFAS-free formulations can meet the requirements laid out in the MIL-PRF-24385. To this end, the JohnsHopkins University Applied Physics Laboratory (JHU/APL) worked to determine readily-available additives that can act to enhance the firefightingcapabilities of mature (i.e., commercially available) and emerging PFAS-free fire suppressants for military use.
