HALON REPLACEMENTS

THE PROPOSED WORK WILL PROVIDE APPLICATION DATA AND PERFORMANCE DESCRIPTIONS OF ALTERNATIVES FOR HALON 1301 FOR AIRCRAFT FIRE PROTECTION AND HALON 1211 FOR GROUND FIRE FIGHTING IN NORMALLY OCCUPIED/UNOCCUPIED AREAS. RESEARCH WILL CONSIDER PHYSICALLY AND CHEMICALLY ACTIVE FIRE EXTINGUISHING AGENTS WHICH HAVE LOW/ZERO ODP, GWP, AND TOXICITIES; IN ADDITION TO RATING HIGH IN THE ASSESSMENT AGAINST APPLICATION PARAMETERS. THE OBJECTIVES WILL BE ACCOMPLISHED FIRST BY ASSESSING APPLICATION CRITERIA AGAINST THE HALON ALTENATIVES ( COMMERCIAL/RESEARCH ) AND OTHER PROVEN AGENTS. FEDERALLY FUNDED DATA BASES AND EXPERIMENTS FOR POTENTIAL AGENTS FOR FIRE/EXPLOSION SUPPRESSION WILL BE ANALYZED. STUDIES WILL LOOK FOR SECOND GENERATION HALON REPLACEMENTS BEYOND HCFCS AND WILL CONSIDER SATURATED HALOCARBONS (PERFLUORO, PHOTOSENSITIVE, HYDROGEN-CONTAINING COMPOUNDS), FLUORINATED CARBONYL COMPOUNDS, UNSATURATED HALOCARBONS (FLUOROAND BROMOFLUORO-ALKENES), HALOGENATED ETHERS (AND REALTAED COM POUNDS WITH OXYGEN ADDED BETWEEN TWO CARBON GROUPS IN AN ALKANE), HALONS CONTAINING IODINE, SULFUR HALIDES, PHOSPHOROUS COMPOUNDS (FIRE RETARDANTS), GROUP IVA ELEMENT STABLE HALIDES, AND VOLATILE ALAKLI AND HEAVY METAL INHLBITORS. ANOTHER PRODUCT OF PHASE I WILL BE FRAMEWORKS OF DATA-BASED AGENT SPECIFICATIONS, WHICH WILL BE FINALIZED IN PHASE II.
