The objective of this Statement of Need was to develop an alternative formulation for use in Department of Defense Class B (flammable liquid) fire-suppression operations in lieu of aqueous film forming foam (AFFF) in accordance with Interim Amendment 3 of MIL-F- 24385F. Specific research areas of interest included:
Proposed solutions that can act as a drop-in replacement that can be employed with a minimum of modification to currently used agent storage and delivery configurations (ship, facility, and fire apparatus) are especially desirable and will be given preferential consideration. Proposals should include an initial assessment of the human health and environmental impacts of proposed ingredients, formulations, and byproducts. Proposers should show clear understanding of past research efforts in this area to avoid duplication of prior work.
Funded projects will appear below as project overviews are posted to the website.
New fluorine-free formulations will enable sustained manufacture and use of AFFF or alternative fire suppression technologies by meeting environmental requirements while maintaining equivalent performance to ensure safety of DoD personnel at airfields and onboard ships.
AFFF is a water-based foam used by the military since the 1970s for fire suppression in ships, shore fixed systems, aircraft hangers, and to extinguish liquid fuel fires. The DoD (primarily the Air Force and Navy) used AFFF mixtures containing significant quantities of perfluorooctane 2 sulfonate (PFOS) and related perfluoroalkyl sulfonates until 2002, when production stopped; however, the DoD continued to use PFOS-containing AFFF stocks for some time after. The DoD inventory still contains at least an estimated 500,000 gallons of PFOS-based AFFF with 423,000 and 97,000 gallons, respectively associated with the Air Force and Navy. The vast majority of DoD's environmental liability likely results from the use of this PFOS-based AFFF. Multiple DoD installations have detected PFOS and perfluorooctanoic acid (PFOA) at 3 to 4 orders of magnitude greater than the current EPA health advisory.
Since 2006, use of AFFF containing PFOS and PFOA has generally been replaced by foams that have fluorosurfactants of 6 carbons or fewer. These newer foams are thought to be less toxic and bioaccumulative, though concerns remain.
Industry has identified potential fluorine-free alternative foams; however, none of these technologies currently meet the performance required for military applications, a problem that extends beyond military operations. Civil aviation continues to use other AFFF or fluorosurfactantfree fire suppression foams that do not meet the performance of AFFF. Alternatives that meet or exceed current AFFF performance requirements without fluoro-surfactants would dramatically reduce the environmental impact of fire suppression training and operations while maintaining the safety of personnel at crash sites or around liquid pool fires.
The cost and time to meet the requirements of this SON are at the discretion of the proposer. Two options are available:
Standard Proposals: These proposals describe a complete research effort. The proposer should incorporate the appropriate time, schedule, and cost requirements to accomplish the scope of work proposed. SERDP projects normally run from two to four years in length and vary considerably in cost consistent with the scope of the effort.
Limited Scope Proposals: Proposers with innovative approaches to the SON that entail high technical risk or have minimal supporting data may submit a Limited Scope Proposal for funding up to $200,000 and approximately one year in duration. Such proposals may be eligible for followon funding if they result in a successful initial project. The objective of these proposals should be to acquire the data necessary to demonstrate proof-of-concept or reduction of risk that will lead to development of a future Standard Proposal. Proposers should submit Limited Scope Proposals in accordance with the SERDP Core Solicitation instructions and deadlines.
