A family of compounds containing bromine used in fighting fires, whose breakdown in the atmosphere depletes stratospheric ozone.
A compound consisting of bromine, fluorine, and carbon. The halons are used as fire extinguishing agents, both in built-in systems and in handheld portable fire extinguishers. Halon production in the U.S. ended on 12/31/93 because they contribute to ozone depletion. They cause ozone depletion because they contain bromine.
A range of compounds containing bromine which is sometimes used in offshore firefighting systems. If released, halon can contribute to stratospheric ozone depletion.
A bromochlorofluorocarbon (BCFC), a chemical consisting of one or more carbon atoms surrounded by fluorine, chlorine and bromine. Halons are commonly used as flame retardants and fire extinguishing agents. Halons have high ODPs.
A compound containing bromine, chlorine, fluorine or carbon in its structure. Halons are used as fire extinguishing agents, both in built-in systems and in handheld portable fire extinguishers. Halons have high ODP because they contain bromine. For further information about Halons, see the Halon table.
A fire protection system suitable for rooms that house computers or other costly equipment which could be destroyed by water. This system releases a firequenching halon gas. Once used, the halon gas must be removed from the area; therefore routine testing is cumbersome.
a compound in which the hydrogen atoms of a hydrocarbon have been replaced by bromine and other halogen atoms; very stable; used in fire extinguishers although it is thought to release bromine that depletes the ozone layer
A gas used to extinguish fires effective only in closed areas.
Special Freon Fire Extinguisher. Generally a 3% to 5% concentration will extinguish fire.
bromo-trifluoro-methane (a gaseous fire-suppressant chemical)
chemical gas fire extinguishing or liquid agent for diminishing the combustion reaction; used mainly in Closed computer rooms, aircraft, and other high-value installations where corrosive chemicals or water extinguishers are judged inappropriate. Effective at low concentrations (5%) as compared with CO2 (34%). Being phased out with suitable replacements in most applications, with very restricted exemptions, due to international environmental concerns with this and other CFCs.
Bromine-containing compounds with long atmospheric lifetimes whose breakdown in the stratosphere causes depletion of ozone. Halons are used in firefighting.
