Environmental Restoration (ER) Program Area
The objective of this Statement of Need (SON) was to identify and develop PFAS-free firefighting formulations that approach the performance characteristics detailed in the latest revision of MIL-PRF-24385 and can enhance fire-suppression performance across multiple scenarios. Specifically, the goal was to address the development of a PFAS-free firefighting formulation that is effective under one or more of the following scenarios:
- Firefighting operations at extreme temperatures (as low as 32 degrees F and up to 125 degrees F);
- Firefighting operations involving various fuels to include Jet A and ethanol-free gasoline (threshold) and optimally, superior performance against mixtures of Jet A, ethanol-free gasoline, and polar solvents;
- Improved burnback resistance and vapor suppression (similar to MIL-PRF-24385);
- Increased fire extinguishing capability at low aspiration and expansion rates (similar to MIL-PRF-24385);
- Improved spreading coefficients that approach or exceed legacy AFFFs (similar to MIL-PRF-24385);
- Allow for use of concentrate in stored, premixed solutions (e.g. portable extinguishers);
- Provide concentrates that are compatible and can be mixed in tanks with other MILSPEC PFAS-free formulations.
Additionally, projects selected address storability and compatibility with DoD equipment, particularly the following issues were of interest:
- Identify, develop, and deploy functional additives and/or modifications of existing fire-fighting equipment to enhance the fire-suppression performance of mature and emerging PFAS-free fire suppressants.
- Determine the impact of gaseous fuel transport through the foam blanket.
- Develop alternative foam production methodologies that are compatible with current fire trucks and infrastructure in support of increased performance.
