Abstract:

Since the signing of the Montreal Protocol on Substances that Harm the Ozone Layer in 1987 and its subsequent amendments, the use of the fire suppressant halon 1301 (CF3Br) has declined sharply to a limited number of essential applications. Production of this chemical in the industrialized world tenninated in January 1994, and the supply of halon 1301 for these essential uses is being met by established reserves. One of the essential uses is for fire protection in military and commercial aircraft. To enable relief from dependence on this environmentally hannful substance, researchers have examined a range of chemical compounds as alternatives. The Department of Defense (DoD) Next Generation Fire Suppression Technology Program (NGP) has been a principal contributor to this search. NGP projects have examined several families of compounds, have created or adapted methods to screen these chemicals, and are developing engineering methods for making the best use of less-than-perfect alternatives to halon 1301 in military aircraft. Supported by the DoD Strategic Environmental Research and Development Program (SERDP), the NGP is now in its fifth year, and planning is underway for the remaining years of this effort. The NGP Technical Coordinating Committee (TCC) deemed it timely to re-evaluate the world of chemistry, identify which chemical families are unlikely to contain usable alternative chemicals, which have been examined sufficiently to know that the best candidates have been already identified, and which families are still in need of scrutiny. Studies of this last group would then be included in the research plans for the remainder of the NGP. This report summarizes the efforts of a task group to perfonn this re-evaluation.
