The continuous search for alternatives to halons as fire suppressants, necessitated by the Montreal Protocol ban on ozone depleting substances, has yielded a few potential replacements. However, these chemically acting agents still pose unresolved toxicity questions and/or are not as effective as halons.This Phase I proposal offers a revolutionary approach to suppress fire by exposure to spectrally selective light. To meet this objective, a four-task work plan is proposed. It includes: (1) Prospective light wavelength(s) for fire suppression will be identified from spectroscopic investigation of light emission from a corona discharge induced by electromagnetic pulse which has already exhibited fire extinction capabilities; (2) Computer modeling will be utilized to assist in the selection of the most promising wavelength(s); (3) Hydrocarbon flames established over a Bunsen burner and/or a counterflow apparatus will be exposed to laser light at the selected wavelengths. Fire suppression will be quantified in terms of reduction is burning velocity (Bunsen) and/or stain rate (counterflow); and (4) A conceptional design of a fire suppression prototype will be rendered based on the experimental and modeling results.Successful demonstration of the principle along with a fundamental understanding of the underlying mechanisms for fire suppression by light will provide a technical foundation for a comprehensive Phase II R&D, leading to a design and construction of a prototype for field demonstration.
