halon is use in a fire fighting system. The problem is that the bromine content in Halon media is giving potential to ozone depletion.
Gas Discharge
No, carbon dioxide is not the only gas that can extinguish a fire. Other gases such as water vapor, nitrogen, and certain types of fire extinguishing agents like halon and foam can also be effective in extinguishing fires by either displacing oxygen or cooling the fuel source.
Just about three hours ago I inhaled a good bit of halon while extinguishing an engine fire on an airplane. So far I felt very jittery and had a hightened heartbeat as if I was on way too much caffeine. I have a sliggt headache, irritated throat, cough. Immediately afterwards I wheezed for about half an hour. I also feel fatigued, this could be due to the halon displacing the oxygen in my body.

The shove it in.
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.

HCFC 123 is the raw base material use to produce a halogeanated, safe/effective and environment friendly fire extinguishing chemical agent called "halotron I". It was introduce in early 1990's to replace the "banned" fire extinguishing agents like, Halon 1211 and BCF's, which were found to have a severe ozone depleting potentials. In contrast, hcfc 123 base fire extinguishing agents has a near zero ozone depletion potentials.
Using the American system for classification, here's the general type of extinguisher used:A (combustible materials) - water, AFFF (aqueous fire fighting film), dry chemicalB (flammable liquid or gas) - NEVER water. Dry chemical, AFFF, Halon, CO2C (electrical fires) - NEVER water. Dry chemical, Halon, CO2D (flammable metals) - NEVER water. Dry POWDER (not dry chemical) such as sodium chloride granules, graphite or copper.
"Halon" (חלון) in Hebrew is "window."
