ADVANTAGES AND DISADVANTAGES OF FOAM FIRE  EXTINGUISHERS

To help customers make informed judgments about the selection of the best extinguishing media for specific operational circumstances, an understanding of the advantages and disadvantages of each is essential. In respect of foam  fire extinguishers

 

ADVANTAGES

 

ü       Smaller Extinguisher – The foam extinguishers are a lot smaller than their standard water equivalents but carry the same Class A Fire rating. Typically a 3Litre Foam will weigh 70% less than a 9Litre water but both have a 13A rating.

ü       Multiple Classes Of Fire Covered - Can be used on both Class A and Class B fires, also if used inadvertently of a fire involving electrics (up to 35Kv) the operator will not get a electric shock.

ü      Quick Knock Down – The AFFF extinguisher medium gives a rapid knock down of the fire and in the case of contained flammable liquid fires the fuel is covered by a film of foam that help cool the fuel as well as sealing in the flammable vapours.

ü      Visibility - Does not impair visibility of the operator when used.

ü       Suitability – The foam extinguisher is non-toxic and non damaging to most materials.  That said the environmental implications of using foam extinguishers should always be considered. Effective against obstructed Class B fires such as car engine bays.  Can be applied to liquids in tanks shielding them from another source of ignition.

 

DISADVANTAGES

 

X        Freezing Problems – Due to the extinguisher being mainly water, the extinguisher is liable to freezing, even with a Low freeze additive added it will only be suitable in temperatures down to minus 10oc.

X        Flammable Liquid Fires - Although can be used flammable liquid fires there are limitations to the liquids covered.  Consulting with the data sheet of the liquids to be covered will help identify which foam should be used, fires involving alcohol require alcohol-resistant aqueous film forming foam (AR-AFFF).

X       Costs – The cost of purchasing and refilling are higher than the water extinguishers and with the environmental implications of disposing of foam will see the refills costs increase.

X       Compatibility – If used with conjunction with powder extinguishers then the powder must be foam compatible or the powder may break down the foam protective blanket.

X       Limit of use - Must not be used on class C,D,E,F fires

How Does Foam Extinguish The Fire

Remove any side of the triangle and the fire (combustion) can not exist
Triangle Of Combustion - Heat Removed

Foam extinguishes Class A Fires by cooling the burning material and removing the heat from the combustion triangle. 

Cooling
Removing the heat
Smothering
Removing the oxygen
Triangle Of Combustion - Oxygen Removed
Foam extinguishes Class B Fires by covering the flammable liquid with a foam blanket, thus cutting off the oxygen supply from the combustion process.  The water content of the foam will help lower the temperature of the flammable liquid.
