Is Halon better than CO2? Carbon dioxide is a trusted non-conductive clean agent and is most effective when used in electronic equipment fires. Halotron is a clean, non-conductive gaseous agent that is an excellent replacement for Halon 1211 extinguishers because it has a lower environmental impact and leaves no residue.
At same time, What is the advantage of Halon fire extinguisher?
Halons are electrically non-conducting and have been acknowledged as the most effective universal extinguishing agent for aircraft use. They work mainly by chemically interrupting the reaction described as the 'Fire Triangle' (Fuel-Oxygen-Heat) which must be sustained for a fire to continue.
On the other hand, Does Halon remove oxygen from the air? Contrary to popular belief, Halon does not remove oxygen from the air, but rather reacts with all elements of a fire. When Halon is discharged, it breaks the chemical chain reaction. This accounts for most of its fire fighting properties. The other properties come from the cooling effect of the expanding gas.
Simply so, Why is Halon not used?
Efforts to find effective replacements for halon in airplane fire-extinguishing and suppression systems are promising, but much work remains. In 1994, halon production ceased in developed countries after scientific evidence suggested that halon contributes to the depletion of the stratospheric ozone layer.
What is a disadvantage of Halon fire extinguishers?
Disadvantages: Generally >35% concentration by volume required for total flooding system. Toxic to humans at >4% by volume. Not the best agent for smoldering deep-seated fires (maintain concentration for >20 minutes)

What is a benefit the Halon extinguisher has over other types?
Well, it's clean, non-volatile and electrically non-conducive. Consider these advantages: Halon is an effective agent on Class B and C fires, the ones you're most likely to see in an aircraft. It works in gas form, so it will not obscure your vision like the powder emitted from dry chemical extinguishers.
What type of fires can Halon be used on?
Halon is one of the most effective fire suppression agents available today. It can be used for Class A, B and C fires with great effect. When it comes to Class D fires however; Halon should never be used. Class D fire are those that involve metals like sodium, potassium, titanium, magnesium and lithium.
How long do Halon fire extinguishers last?
Halon fire extinguishers require the same six year maintenance and 12 year hydro test that other fire extinguishers require.
How does Halon suppress a fire?
Halon is a liquefied, compressed gas that extinguishes fires by reacting with the fire's elements and breaks the chemical chain reaction. A fire needs three elements to sustain – oxygen, heat, and fuel. When you disrupt or remove an element, the fire cannot sustain itself.
Is halon gas heavier than air?
Adverse health effects and symptoms: Halon 1211 is a simple asphyxiate. The gas is heavier than air and may accumulate in low spaces causing a deficiency of oxygen and cause rapid suffocation. Symptoms include drowsiness and unconsciousness.
Why is carbon dioxide so effective for use in extinguishing Class C fire?
Class C fires, which involve energized electrical equipment, can also be extinguished with CO2. CO2 displaces the oxygen to extinguish the fire. This “cloud” of CO2 reduces the oxygen in the air around the fire and smothers it.
What happens if you inhale halon?
Inhaling halon compounds in high concentrations can cause central nervous system disorders including dizziness, unconsciousness and tingling in the arms and legs. Exposure to halon compounds may also cause cardiac sensitization resulting in irregular heartbeats and even heart attacks (in a severe circumstances).

How does halon deplete the ozone?
They are used in fire extinguishers and other firefighting equipment. Because of their bromine content, halons can destroy ozone molecules(O3) very effectively, thereby contributing to the depletion of ozone and the creation of holes in the ozone layer of the stratosphere .
What is the most effective fire extinguisher?
