The objective of this program was to demonstrate the effectiveness and to determine the toxicity and associated risks of labile bromine compounds as halon replacements for suppression of engine nacelle and dry-bay fires in military aircraft. Tests performed during this program have shown that labile bromine compounds generally and phosphorous tribromide (PBr3) in particular, are more effective than Halon 1301 for both engine nacelle and dry-bay fire extinguishment and have neither ozone depletion nor global warming potentials. Theoretical electronic structure calculations and experimental chemical kinetics investigations were performed to enhance the understanding of the chemical action of PBr3 fire suppression. Independent toxicity studies supervised by the tri-services toxicology laboratory (AL/OET) at Wright Patterson Air Force Base, determined that PBr3 was neither mutagenic nor toxic to aquatic organisms. Additional data on the toxicological properties of PBr3 were acquired by AL/OET including dermal irritation and acute and subchronic inhalation toxicity. These results formed the basis of their independent risk assessment, which concludes that use of PBr3 as a halon replacement is safe in normally unoccupied spaces such as engine nacelles or dry-bays.

What is good for fighting fires is not always good for the environment. In the case of halons, their long atmospheric lifetimes and high ozone destruction potential makes them extremely damaging to the stratospheric ozone layer, which protects humans, animals and plants from the damaging effects of ultraviolet solar radiation. Developing countries face the challenge of ensuring effective fire protection while at the same time eliminating their reliance on halons. This publication presents case studies that show how different organizations and countries have successfully approached and addressed various aspects of halon management.
