How does halon 1301 work

They are most often used in systems that protect irreplaceable or high value products such as data centers, museums, power plants, etc.

We can supply the gasses to refill extinguishers, as well as decant any extinguisher. Unfortunately, we do not provide filling services for Halon fire extinguishers at this time. Accessibility Menu.

Both Halon variants work by a combination of chemical and physical effects. The chemical effects, which are dominant in their overall effect, are achieved by the atoms in the gas directly inhibiting combustion in two different ways:. Temperature reduction occurs, whenever a non-reactive gas is added to a flammable gas, because the heat liberated by the reaction of oxygen molecules with a fuel source must be distributed into the overall environment.

The rate of the combustive chemical reaction decreases rapidly with reductions in temperature and, if the concentration of added inert gas is high enough, the flame chemistry fails altogether. Halon gas mixtures are not only inert but of low temperature when released from their pressurised state. Dilution is a simple matter of reducing the collision frequency of the oxygen and fuel source so that there is a reduction in chemical reaction rates.

The magnitude of this effect, however, is relatively small compared to chemical inhibition and thermal effects, the former of these being the predominant one. The chemical consituents in Halon gases, and the products of the reactions they produce when used to fight fires, have been identified as causing damage to the Ozone layer. Halon is still in use today, but is falling out of favor for many uses due to its environmental impact.

Europe, and Australia have severely restricted its use, since the Montreal Protocol of Since the Montreal Protocol Halon is one of the only ozone depleting chemicals with concentrations still rising, due to the release of fire extinguishing equipment already deployed.

Halons are fire extinguishing agents which are gaseous when discharged in the aircraft environment. Halons have, until recently, been in almost universal use in aircraft fire extinguishers , both portable and fixed.

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. They do not produce residues and therefore do not cause secondary damage. However, the fumes are toxic if inhaled and all practicable precautions should be taken when they are used.

The chemical constituents in Halon gases, and the products of the reactions they induce when discharged on fires, have been identified as causing damage to the Ozone layer. As a result, their manufacture and use have been banned for many years in most countries and non-essential uses have been eliminated.
