There are six different classes of fire and several different types of fire extinguishers all designed and manufactured to tackle specific fire classes.
- Class A –Fires involving solid materials – wood, paper or textiles.
- Class B – fires involving liquids – cleaning fluids, solvents, fuels, adhesives and paints.
- Class C – fires involving gases – natural gases, LPG (Liquid Petroleum Gas) and other types of gases forming a flammable or explosive atmosphere.
- Class D – fires involving metals – metals are not often thought of as combustible material but there are acceptations such as sodium. There are good conductors and help a fire spread.
- Electrical – fires involving live electrical equipment – electricity is more a source of ignition
- Class F – fires involving cooking oils – deep-fat fryers.
Fire Extinguisher FAQs
FIRE EXTINGUISHER Types Cheltenham
Water-based Fire Extinguishers
These fire extinguishers fight fire by spraying water and are most effective against solid organic materials such as; wood, plastics, paper, coal, etc.
They are not for use against electrical or fat/oil based fires.
Foam Fire Extinguishers
These foam-based extinguishers utilise foam to douses the fire. This results in a layer between the fuel surface and flames.
Foam extinguishers are also suitable for both solid and liquid firebases.
They are not suitable for use against electrical or fat pan/oil-based fires.
Co2 Fire Extinguishers
CO2 Fire Extinguishers shoot carbon dioxide. CO2 removes the oxygen from the chemical reaction, effectively smothering the fire. This makes the CO2 extinguisher extremely effective.
Please bear in mind, the CO2 can dissipate fairly quickly, allowing the fire to potentially reignite. This type of extinguisher is ideal for electrical fires and live electrical equipment.
Powder Based Fire Extinguishers
A powder based extinguisher blasts the fire with a special powder. This powder causes the flames to cool to a point where the chemical reaction can no longer occur.
Suitable or use against organic solids, grease/oil, petrol and gas fires.
The main problem with these extinguishers is the powder, which can cause breathing difficulties. It causes a ‘fog’ which can hinder evacuation and is also extremely messy to clear away. British Standards no longer permit ABC Powder Extinguishers to be used in offices and living accommodation due to this problem. ABC Powder Extinguishers are therefore only recommended for use in well-ventilated areas.
Wet Chemical Fire Extinguishers
These fire extinguishers are perfect for class F fires involving chip fat/oil based fires. This type of extinguishers sprays out a fine mist, which sits as a layer of foam on top.
You’re likely to find this type of equipment in locations where oil is cooked to a high temperature.
