Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Halon 1301 is widely used by the U.S. Military [7] and NASA in a 2-3/4 lb portable extinguisher with a sealed, disposable cylinder for quick recharging. Other agents such as CO 2 and FE-36 (HFC-236fa) wet chemical are largely replacing halon 1301 for environmental concerns. Civilian models in 2-3/4, 3, and 4 lb sizes were also made.
[citation needed]) Halon 1211 also has low toxicity, although it is more toxic than Halon 1301, and thus considered unsuitable for flooding systems. However, Halon 1301 fire suppression is not completely non-toxic; very high temperature flame, or contact with red-hot metal, can cause decomposition of Halon 1301 to toxic byproducts.
Aircraft carriers are warships that act as airbases for carrier-based aircraft. In the United States Navy , these ships are designated with hull classification symbols such as CV (Aircraft Carrier), CVA (Attack Aircraft Carrier), CVB (Large Aircraft Carrier), CVL (Light Aircraft Carrier), CVE (Escort Aircraft Carrier), CVS (Antisubmarine ...
PhostrEx is a fire suppression agent developed for use in aviation applications to replace halon, a greenhouse gas (GHG). It was developed by Eclipse Aviation for use aboard their Eclipse 500 very light jets as an engine fire suppression system , and is now being marketed to other aviation manufacturers.
Halotron I was originally introduced in 1992 as a replacement for Halon 1211(bromochlorodifluoromethane), a substance known for its significant ozone-depleting properties. While Halon 1211 has a global warming potential (GWP) of 2,070, [2] Halotron I's GWP is considerably lower at 77, reflecting a 96% reduction in environmental impact. [3]
