Bromotrifluoromethane, commonly referred to by the code numbers Halon 1301, R13B1, Halon 13B1 or BTM, is an organic halide with the chemical formula C Br F 3. It is used for gaseous fire suppression as a far less toxic alternative to bromochloromethane. [3]
For many years, Halon 1301 was the holy grail of fire suppressants for high-value assets that would be damaged by traditional sprinkler systems. But, in 1989, when the Montreal Protocol determined that halon depleted the ozone layer, and the U.S. Environmental Protection Agency subsequently banned its manufacture in 1994, the search was on for ...
Halon, a gaseous fire suppressant, gained popularity in the mid-20th century for its exceptional ability to extinguish fires rapidly without leaving harmful residues. Its chemical composition typically includes bromine, fluorine, and carbon, making it effective in disrupting the combustion process.
Learn about EPA's effort to address ozone layer depletion by establishing installation, handling, and emissions requirements for halon fire suppression systems.
Halons are nonconductors of electricity and can be used in fighting fires in flammable liquids and most solid combustible materials, including those in electrical equipment; they are ineffective on fuels containing their own oxidizing agent or highly reactive metals, such as sodium or potassium.
Fire suppression and explosion protection have used halons in many applications because they are electrically non-conductive, dissipate rapidly without residue, are safe for limited human exposure, and are extremely efficient in extinguishing most types of fires.
Halon ® —the name is still almost synonymous with clean agent fire suppression. Developed by Dupont ® in the 1950s, Halon became the go-to agent where clean agents were needed. Its adoption worldwide garnered Halon the lion’s share of the market.
Discover key differences between halon and clean agent for fire suppression. Learn more about which option is best for your needs. Halon, once a widely-used fire suppressant, has faced environmental concerns leading to its phase-out.
significant efforts on studying halon fire suppression. The US National Academy of Sciences held a symposium on “An Appraisal of Halogenated Fire Extinguishing Agents” in April 1972. Issues included toxicity aspects and practical applications of fire suppression for a variety of scenarios.
Beginning with a thorough understanding of the mechanism whereby halon adversely influences the ozone layer, and possibly contributes to global warming, assess the research effort directed at finding a substitute for halon as a fire and explosion suppressant, and evaluate any potential substitute for its (a) effectiveness compared to halon, (b ...
