- Abstract
- AFFF agents are the most efficient fire fighting foams to extinguish hydrocarbon fuel fires, but have limited foam life and burnback resistance, poor diodegradability and toxic effects on aquatic life forms. In this Phase 1 project, parameters were established for AFFF agent replacements having improved burnback resistance and less of a negative environmental impact without sacrificing the superior fire extinguishing capabilities of AFFF agents. In order to establish such parameters, including component specifications and performance criteria, several developmental agent compositions were prepared from developmental fluorochemical surfactants, selected commercial hydrocarbon surfactants and other additives. Evaluation results obtained, including MIL-F-24385F 28 sq. ft. test fires results indicate that agents with significantly reduced fluorochemical surfactant content having improved environmental and performance properties, can be developed.
