Fire Extinguisher Training - CO2, H2O and Foam

It is regular information that fire dousers can put out flames when utilized effectively and it's frequently the primary thing to search for when a little fire has begun. In any case it is regularly ignored that there are distinctive kinds of flame quenchers for various sorts of flames and utilizing the wrong kind of flame douser can really exacerbate things. The accompanying 3 sorts of flame quenchers are particularly intended to battle certain kinds of flames.

1. Water

Water is the most generally utilized douser specialist and utilized for class A flames.

There are fundamentally two kinds of water quencher:

(a) The gas CO2 cartridge worked douser. At the point when penetrated by a plunger the gas adds weight to the body of the quencher, consequently removing the water and creating a capable stream.

(b) Stored Pressure dousers. Here the primary douser body is always under strain with dry air or nitrogen and is worked by opening the press hold release valve.

These dousers are accessible with 2, 3, 6 or 9 liter limit bodies and in this manner give options where weight and availability issues emerge.

2. Froth

Froth can be utilized on class B fires where it will stream over the surface and cover the fire. The froth delivered comprises of little froth bubbles which have an exceptionally velvety consistency.

Another kind of froth, A.F.F.F. (watery film shaping froth) is ending up progressively prominent.

This can likewise be utilized on class A flames and it has preferable quenching properties over water, hence a lighter, littler douser can be given that has a similar smothering capacity of a bigger water quencher.

Froth quenchers can be pressurized either by the CO2 gas cartridge strategy or by Stored Pressure.

These dousers come in an indistinguishable limits from that of water - 2, 3, 6 or 9 liters.

3. Carbon Dioxide

Planned particularly to manage Class B, C and electrical fire dangers. These dousers contain carbon dioxide gas at high weight so that as a result, the gas contained inside the chamber is in fluid frame. CO2 is an unscented fluid, generally non-poisonous, however it is an 'asphyxiant'. At the point when gas is discharged, so fast is the rate of release that solidifying up of the valve may happen.

The valve amass contains a 'piercer' which, when worked, breaks the seal, enabling the gas to escape through the release horn. The horn is so intended to stop entrainment of the air, generally, the high speed release would act like a blowtorch and increment the seriousness of the fire, a methods for controlling the rate of release is typically given.

CO2 is a non-conveyor of power and this quencher can be utilized with wellbeing on all flames of electrical beginning with no risk of the administrator accepting an electric stun.

They are likewise to a great degree helpful in flames including combustible fluids as the gas shapes a cover over the consuming surface of the fluid, barring the oxygen and covering the fire.

These quenchers come in 2 or 5 kg limits.
