Abstract Halon 1301 has served as a be all and end all fire extinguishing chemical for 20 plus years. Its rapid extinguishing action, coupled with its low toxicity, low installed system cost and cleanliness, had made many addicts to its use in place of the traditional not-in-kind alternative approaches (water, carbon dioxide, powders, and foams). Unfortunately for the fire protection community, it, along with all other chlorine and bromine containing halogens, is being phased out of production and use due to its now well established contribution to adverse impact on stratospheric ozone. The history of the theory and experimental verification of ozone depletion and the state of local, national and global regulations pertaining to the control of ozone depleting substances will not be addressed here except for the following observation: The realization by Rowland and Molina in 1973 (published in 1974) that stratospheric chlorine could destroy ozone occurred at around the same time that halon 1301 was becoming a major factor in industrial and commercial fire protection.
