Fire Extinguishers Bishops Cleeve, Cheltenham, Gloucestershire


Fire Extinguishers and Classes of Fires

There are x5 Classes of Fire + x1 Electrical Risk (E)


The European Standard BS EN3 specifies that All Fire Extinguisher Bodies are to be coloured "RED"
regardless of the contents of the extinguisher

All Extinguishers now have a 5% area of the label that is Colour Coded which denotes its contents
(see Colour Coded Bands below)

Water Extinguishers: Suitable for use on Class A Fires

Suitable for use on materials such as - Wood, Paper, Textiles & Fabrics

The water has a cooling effect on the fire, therefore there is insufficient heat to sustain the fire

They are available in = 9 litre and 6 litre capacity


Foam (AFFF) Spray Extinguishers:

Suitable for use on Class A & B Fires

Suitable for use on fires involving flammable liquids such as - Oils, Spirits, Greases, Fats and Certain Plastics

The foam has a blanketing effect that knocks down the flames, smothering them, thus preventing re-ignition of the flammable vapours by sealing the surface of the solution

These extinguishers have passed the Electrical Conductivity Test

They are available in = 9 litre, 6 litre and 2 litre capacity

ABC - Dry Powder Extinguishers: Suitable for use on Class A, B, C & E Fires

POWDER Extinguishers are No Longer Suitable for Use Indoors
unless mitigated by a Health & Safety Risk Assessment

Therefore All Powder Extinguishers should be Replaced with an alternative Medium or Mediums

If You Still Have Powder Extinguishers in Your Building This Could "INVALIDATE YOUR INSURANCE"

in order to cover the same risks the alternative to using Powder is:- AFFF (Foam) and CO2 combined

As a multi purpose medium powder is suitable for use on all types of fires, except burning metal
the two main risks being, running fuel fires (flammable liquids) and flammable gas fires (LPG)

The powder interferes with the combustion process to provide a rapid knock down effect on the flames. Although Dry Powder can be used on electrical equipment and machinery, care should be taken as although it will put out the fire it will damage the equipment

Powder is extremely Messy to clean up, clean up can be very costly and time consuming
Powder reduces visibility and as such can hinder and jepodise escape
Powder can be an irritant and can cause breathing problems
Powder can be corrosive and can damage certain materials or items

They are available in = 9kg, 6kg, 4kg, 2kg and 1kg capacity

Class D - Dry Powder Extinguishers: Suitable for use on Class D Fires

Suitable for use on fires caused by the combustion of metals such as Aluminium, Magnesium, Lithium, Sodium, Potassium and their alloys

Carbon Dioxide Extinguishers:
Suitable for use on Class B & E Fires

Suitable for use on fires involving flammable liquids such as - Oils, Fats & Solvents & Electrical hazards. CO2 is non corrosive and non conductive, it is harmless to electrical equipment and machinery

The CO2 excludes the oxygen from the fire and smothers the flames thus preventing re-ignition

They are available in = 5kg and 2kg capacity

Wet Chemical Extinguishers: Suitable for use on Class F Fires

This extinguisher was developed specifically for tackling Kitchen "Fat Fryer / Cooking Oil" fires, which are the most difficult types of fire to extinguish safely

Available in = 6 litre capacity

Halon Extinguishers: Warning "illegal" No Longer Permitted

As of December 2003 Halon was withdrawn from service and it is now an Illegal and an offence to possess and use such an extinguisher
There are exceptions to this rule where certain industries like the armed forces or aviation industry can still have and use halon but they must hold a certificate that conforms to BS Regulation No. 2037/2000 (1) Annex VII "Critical Uses"
