Abstract:

The Department of Defense (DOD) is entering the third year of its Next Generation Fire Suppression Technology Program (NGP). The NGP goal is to demonstrate, by 2005, retrofitable, economically feasible, environmentally acceptable and user-safe processes, techniques, and fluids that meet the operational requirements currently satisfied by halon 1301 systems in aircraft, ships, land combat vehicles, and critical mission support facilities. If successful, the NGP could eliminate DoD dependence on a harmful substance no longer in national production, minimize any readiness impacts that could result if halon 1301 use restrictions were imposed in the future, and achieve these at greatly reduced cost. The potential fire locations for which alternatives to halon 1301 are sought include aircraft engine nacelles, dry bays, cargo bays, and fuel tanks; ground vehicle crew compartments; and shipboard machinery spaces and storage compartments. The hazards to be avoided include hatm to people, thermal damage, post-fire corrosion, loss of visibility, and over-pressure. Successful candidates must thus do well in: fire suppression efficiency and reignition quenching, ozone depletion potential (ODP), global warming potential (GWP), atmospheric lifetime, suppressant residue level, electrical conductivity, metals non-corrosivity and polymeric materials compatibility, long-term storage stability, low toxicity of the chemical and its combustion and decomposition products, speed of dispersion, safety and occupational health requirements. To be cost-effective, the suppressant and storage/delivery system must be of light weight and low volume, as well as compatible with the host designs of existing platforms.
