What is Halon?

Halon is a fire suppressant agent found in both Fire Suppression Systems (Halon 1301) and in hand held Fire Extinguishers (Halon 1211). This is the most effective extinguishing agent available. Halon is a clean agent, which means it leaves no residue when used, so it causes no damage to your property. 

Is Halon Banned?

The use of Halon is not banned, but rather the manufacturing of Halon globally, because of its Ozone Depleting properties. In 1987 the Montreal Protocol found Halon was damaging the environment. In response to this, the U.S. created the Clean Air Act.  

Who uses Halon?

Halon is still used in many applications.

How does Halon work?

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. Because of this, Halon can be safely used in an occupied space.
