Fire extinguishers within commercial building, churches, stadiums etc are required by law and in most circumstances your insurance
will stipulate that they are both installed and maintain within your building. Further to this they are installed to give the
occupier a chance to extinguish or control small fires, remember most fire start small and can be extinguished with a portable fire
extinguisher.
Fire extinguishers come in various types, sizes and versions, it is important that the correct extinguisher
is install to cover the risks present. The extinguisher types are
These are the cheapest of the portable fire extinguishers and are for use on Class A, solids such as wood, paper, leaves, sugar, straw,
plastic etc. Also available under water types are the water spray and water with additive extinguishers, these both have the
advantage of being smaller and electrically non conductive over the standard 9Ltr water jet extinguisher.
Foam extinguishers are for use on the same Class A solids as the water extinguishers, but can also be used on Class B flammable liquids
such as petrol, diesel, paraffin, white spirit, paint and includes liquefiable solids such as wax, grease, margarine
and shoe polish. also available under foam types are the foam spray extinguishers, these both have the advantage
of being smaller and electrically non conductive over the standard 9Ltr branchpipe type extinguisher. Foam is not recommended
for cooking fat/oil fires.
ABC Dry Powder extinguishers are for use on the same Class A, Class B fires as defines above but can also be used on gas fires such
as propane, butane, acetylene, hydrogen, ammonia, methane and ethylene. It is a versatile extinguisher but is not ideal in confined
spaces or in buildings as it reduces visibility and can cause damage from its messy extinguishing agent. There are special
powder extinguishers on the market to cover class D, metal fires. These include magnesium, aluminium, titanium, sodium, lithium, caesium,
manganese, cobalt, cadmium and potassium.
The Wet Chemical or Class F fire extinguisher is designed for fires involving cooking fats and oils. The extinguisher has a low velocity
applicator come lance, this means the operator is kept away from the fire and the risk of splashing the oil about when applying the
foam solution is reduced. These extinguishers are electrically non conductive and have been designed with chip shops, restaurants
and fast food outlets in mind.
Co2 extinguisher provides suburb fire fighting properties when dealing with fires involving electricity. As the extinguishing
agent is a gas it can cases and cabinets containing electrical items very quickly and easily. Ideal for fires within photocopiers,
computers, electrical switchgear and computer screens. It is a very clean extinguishing agent. Co2 can be used on flammable
liquid, Class B fires. Extreme caution must be taken not to put the discharge horn too close to the burning liquid, they also
have no post fire security and the liquid could burst back into flames.
Why do I need a fire extinguisher?
Principles of Fire
Fire (combustion) is a rapid, persistent chemical change that releases heat and light and is accompanied by flame and broadly
speaking the fire requires three elements to exist, these are
There are exceptions to this statement, the occurrences
of these exceptions are both few and very specialised in character.
The fire triangle symbol has been used for years to easily
explain the process of combustion.
Remove any side of the triangle and the fire (combustion) can not exist
Methods of Extinguishing Fires
Using the diagram above you can see that by removing any of the three elements from the triangle and the fire can not exist, the three
main methods of extinguishing a fire are
Cooling
i.e. removing the heat
Starving
i.e. removing the fuel
Starving is not always practice but can be the preferred method.
Cooling and smothering are the methods that are most widely
used.
Some fire extinguishers such as Dry Powder interrupt the chain reactions of combustion of Class B&C Fires and
extinguish Class A fires by chemical and physical reactions of the various ingredients of the Dry Powder extinguishing media.
Smothering
i.e. removing the Oxygen
