Feasibility of a Jet-Stirred Reactor for Evaluating Replacements for Halon Fire Retardants.

Abstract

Halons have been used as extinguishing agents for over 20 years. This type of fire suppression dates back to the late 1930's and 1940's when researchers discovered that halogenated methanes reduced flame velocities and inhibited ignition (Zentler-Gordon, 1940). Further research resulted in the development of commercial halogenated fire suppression agents. The two most popular halons are Halon 1301 (CF3Br) and Halon 1211 (CF2BrCl). Halon 1301 is mainly used in fixed location discharge stations due to its low boiling point (-58 C). The higher boiling point of Halon 1211 (24 C) has made it popular with portable fire extinguisher applications. The principal advantages of halons are their low extinguishing concentration requirements and relatively non-toxic byproducts. One important benefit is that they do not damage equipment, which is critical in aircraft, computer facilities and nuclear plant electrical control rooms. jg p.6
