Functional Additives to Enhance PFAS-Free Fire Suppressants (WP22-3284) Limited Scope Final Report
Abstract
The work conducted in this study provides a basis for further development and assessment of additives to enhance performance of commercially available PFAS-free foams with the ultimate object of equaling the capabilities of legacy AFFF. Additional work to further characterize the successful additives tested, and related modified additives based on these results, is a critical next step in understanding the molecular basis for why these additives improve fire suppression and to optimize foam solution mixture ratios for military performance requirements. Building on this exploration, JHU/APL's industry partners can help to conduct further testing and assess scalable production methods in order to transition to use of novel additive mixtures that can supplant PFAS containing AFFF. This transition is essential due to the identified risks of PFAS, including persistence in the environment, bioaccumulation, and toxic human health effects.
