DEVELOPMENT OF A FOAM COMPATIBLE WITH DRY POWDER

Abstract

A new fluorinated proteinaceous fire-fighting foaming agent, that is compatible with commercially available dry chemicals, was developed. This extinguishant, which meets the fire requirements for conventional protein foams, will be used in a dual agent application system with potassium bicarbonate dry powder (Purple K). Combined application of the new compatible foam and Purple K dry chemical appears to provide outstanding means for rapid control and security of flammable liquid fuel fires. Two indoor laboratory-scale tests were devised which were found useful in screening candidate foam-liquid formulations for compatibility with dry chemicals. Also developed were three large-scale outdoor compatibility tests which represent various field fire-fighting practices incorporating the combined usage of foam and dry powder. The screening tests were found to correlate very favorably with the field compatibility tests.
