What chemical in fire extinguishers destroys ozone?
See "What is causing the depletion of the ozone layer?" in the "Related questions" section below.
Which gas is used in fire extinguishers?

What is the difference between dry chemical and hcfc 123 fire extinguisher?
The difference between a dry chemical and a hcfc 123 fire extinguisher is the material used to extinguish. Dy chemical fire extinguishers typically contain a fine white powder composed mainly of monoammonium phosphate. This powder extinguishes the fire but creates a lot of smoke and is highly corrosive. Hcfc fire extinguishers use Halon instead. Halon is a liquefied, compressed gas that cuts off the combustion reaction while it is happening. Halon has very few risks and very little is needed to extinguish fires.
What is Halon?
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).
What gas is in a extinguisher?

Why is halon illegal?

What is a disadvantage of Halon fire extinguishers?
Halon inhalation can affect the cardiovascular and nervous system and can cause death in humans and other mammals at HIGH CONCENTRATIONS. It also displaces breathable air within the compartment. In theory, a properly installed and calibrated system will include enough oxygen to support human life, but in practice it would be wise to immediately evacuate anyone who does not have self-contained breathing apparatus.
