Aircraft fire protection: The Advantages of a fire extinguisher halon

Halons are fire quenching agents which are vaporous when released in the aircraft environment. Halons have, as of not long ago, been in verging on widespread use in aircraft fire extinguisher halon, both fixed and portable. They exist in two structures - as Halon 1211, BromoChlorodiFluoromethane (CBrClF2) otherwise called 'BCF', and as Halon 1301, Bromotrifluoromethane (CBrF3). At the time of installation fire extinguisher halon 1301 is utilized.

The adequacy of halons in dousing flames emerges from their activity in intruding on chain responses that engender the burning procedure. Halons are nonconductors of power and can be utilized as a part of battling flames in combustible fluids and most strong flammable materials, incorporating those in electrical hardware; they are inadequate on fills containing their own oxidizing specialists or very receptive metals, for example, sodium or potassium. Halon 1301 (bromotrifluoromethane) is particularly supported for extinguishing fires quenching flames including electronic equipments on the grounds that it leaves no deposit and does not bring about electrical short circuits or harming erosion of the component.

Halons are electrically non-leading and have been recognized as the best widespread extinguishing agent for the aircraft purpose. They work principally by chemically interrupting as the 'Fire Triangle'(Fuel-Oxygen-Heat) which must be supported for a fire to proceed. They don't deliver residues and in this way don't bring about optional harm. In any case, the fumes are poisonous if breathed in and precaution needs to be taken when they are utilized.

Every airplane created in the most recent thirty years has utilized Halon 1301 for motor flame assurance and in numerous cases payload and dry straight security also. For all intents and purposes US Organizations including the Military, FAA and PA have acknowledged the fire extinguisher halon 1301as essential use.

Fire needs three components to flourish: fuel, oxygen and warmth. The most widely recognized smothering operators like water, carbon dioxide, dry synthetic and froths assault the flame physically to deny the flame of one or a greater amount of the three discriminating components required for proliferation. Fire extinguisher halon varies in the way it puts out the flame. It offers some of water's cooling impact and some of carbon dioxide's covering activity; however its crucial dousing method lies in its ability to artificially respond with the fire's segments. fire extinguisher halon really intrudes on the chain response of flame.

Water is extremely powerful on class a flames (normal combustibles like wood and paper). Halon is viable on basic combustibles but rather Halon is additionally viable on class B (combustible fluids), and it doesn't lead power back to the quencher administrator (class C).


Halon is like CO2 in that it is suitable for utilization in chilly climate and leaves no deposit. Dissimilar to CO2, be that as it may, fire extinguisher halon does not dislodge the let some circulation into of the zone where it is apportioned. Additionally, dissimilar to CO2, there is no threat of "cool stunning" flying or other delicate electrical gear. Hence with such advantages of fire extinguisher halon one can sale his/her old Halon to a company who re-use it in aircraft safety products.
