Halon is a general term for any of several compounds composed of carbon, possibly hydrogen, and halogens. The number tells which: halon 1301 is trifluorobromomethane, CF3Br.
Halons are extremely unreactive and used in built-in fire suppression systems where water would probably cause more damage than the fire itself, such as computer rooms. The halon "smothers" the fire, preventing oxygen from reaching the burning materials. Most halons (that are used in fire extinguishers, anyway) are heavy gases, or low-boiling liquids.
One of the benefits of halon is that since it's nearly inert it doesn't cause any damage on its own; it excludes oxygen, puts out the fire, and then dissipates into the atmosphere. The drawback is that halon systems are quite expensive, and while they're not actually toxic, they'll suffocate people just as well as they suffocate fire (which is why locations with halon systems have warning signs to tell people to get out if the alarm goes off... this is a good idea with fires in general, but with halon systems it's even more important).
The gas discharge fire suppression system uses Halon gas or an EPA-approved gas to replace Halon. Halon interferes with the fire's chemical combustion and does not harm computer systems, which made it a popular solution. Halon was banned in 1994, when it was discovered that it was an ozone depleting gas; however, some of these systems still exist. The replacements, known as clean-agent fire suppression systems, are carbon dioxide, argon, Inergen, and FM200.
Halons are harmful for ozone. They also react with ozone to deplete it.
halon is another name. they deplete ozone.
hello uh the answer is carbon(IV) chloride It used to be called Dry Cleaning Fluid. Another "official" name for it is tetrachloromethane. A brand name is Halon 104.
Halons contain chlorine and bromine atoms which, when released into the atmosphere, can react with ozone molecules. These reactions lead to the breakdown of ozone molecules, causing ozone depletion. Halons are potent ozone-depleting substances and are now heavily regulated under international agreements to help protect the ozone layer.
"Halon" (חלון) in Hebrew is "window."
halon is use in a fire fighting system. The problem is that the bromine content in Halon media is giving potential to ozone depletion.
Before we start, let's clear something up: The storage, use and sale of RECYCLED Halon is not illegal. In fact, it is encouraged, and many professional fire protection services companies specialize in Halon recycling and recharge. That said, the production of NEW Halon was outlawed in 1994 under the Clean Air Act. Halon is a potent CFC and is very damaging to the atmosphere. However, since their is no known method of disposing of existing Halon supplies (and since it is such a powerful fire suppressant), recycled Halon is still a popular means of controlling fires in many commercial applications. Fun fact: the FAA requires Halon use on all commercial airlines!
To date (2013) there are no known long term effects associated with halon exposure.
The word "halon" is pronounced as "hā-lon", with the emphasis on the first syllable "hā".
No, Halon and FM-200 are not the same product. Halon refers to a class of bromine-containing compounds used in fire suppression, notably Halon 1301, which has been largely phased out due to its ozone-depleting properties. FM-200, on the other hand, is a more environmentally friendly clean agent known as HFC-227ea, which does not harm the ozone layer and is commonly used as a replacement for Halon in fire protection systems.
Yes, Halon fire extinguishers can be used on electrical equipment- and in fact are often recommended.

Halon is harmful to the ozone layer as it contains chlorine and bromine atoms, which deplete ozone molecules. Due to its significant ozone depleting potential, halon has been banned by the Montreal Protocol to protect the Earth's ozone layer. Its production and use are restricted to specific critical applications such as aviation and military where no suitable alternative exists.
