Foam Fire Extinguishers UK are Suitable for Both Class A & B Fires.
Foam Fire Extinguishers UK – Colour Cream – Class A & B Fires.
Foam Fire Extinguishers are ideal for both A & B class fires. Extinguishers containing the agent AFFF (Aqueous Film Forming Foam) are especially suited for fires involving materials such as fats, petrol, oils, paints, etc. This foam also cools solid material fires.
Conventional foam does not work well on some liquids so it isn’t recommended for home use, but foam is very effective on most fires – except electrical and chip pan fires.
Warning – Foam fire extinguishers are NOT suitable for electrical or deep fat fryer fires – wet chemical extinguishers should be used.
Foam fire extinguishers come in a variety of sizes and types and are available as either full jet or super-spray versions.The range of the jet is 2-6.M – discharges time 20-68 seconds- both variables according to type.
Application- Read the instructions and make yourself familiar with HOW TO USE IT. Don’t leave it until you have a fire!
- Pull out the safety pin- then squeeze the lever.
- For solids, aim the jet at the base of the flames and move it over the area of the fire.
- For liquids, don’t aim the foam straight at the fire, which can spread the fire onto the surrounding area, rather aim it at a vertical surface.
- If the fire is in a container, direct the foam at the inside edge of the container, which allows the foam to build up and flow across the surface of the liquid to smother the fire.
How Do Foam Fire Extinguishers UK Work?
By pulling out the safety pin and depressing the lever at the top of the cylinder, the material is released under high pressure.Foam extinguishers intefere with the chemical reaction of the fire, by coating the fuel with a layer of foam, separating it from the oxygen.
A blanket is formed on the surface of a burning liquid.AFFF also penetrates and seals the fire, which protects against re-ignition.
Fire extinguishers should be sited in a conspicuous position on a wall, (brackets are usually supplied) or on a stand; they should have a sign above to identify the extinguisher type and application.
Fire Extinguisher Maintenance is Important.-You should inspect your fire extinguishers at least once a month and have them serviced once a year, or as recommended by the manufacturer.
Fire extinguishers should be pressure tested after a number of years in use, to ensure that the cylinder is still safe. Consult your extinguisher manual, the label, or the manufacturer to find out when yours require testing.
N.B.The colour coding of fire extinguishers has changed.- The NEW types now comply with the European Standard BS EN3. They have red bodies with a section of colour, up to 5% of the surface, to indicate the contents of the extinguisher.
