Types Of Fire Extinguishers And Their Uses
Types Of Fire Extinguishers And Their Uses – Fire extinguishers are available as portable and portable units that are used to extinguish fires in a manner that allows the fire to spread and cool the equipment and extinguish the fire with oxygen. Fire extinguishers are usually small tanks containing compressed gas and a hand pump to pump water through a nozzle.
In an emergency, the first thing most people do is read the instructions on the fire extinguisher so that it can be used to fight the fire. But early detection and being able to put out the right fire extinguishers can save life and property right away.
Types Of Fire Extinguishers And Their Uses
Since fire comes in many forms, it is good to know the type of fire and what is the best way to put it out quickly.
Understanding Different Types Of Fire Extinguishers And Their Uses
It must be fireproof according to the materials involved, so it is classified as type 5.
Class F – The fire is cooking oil and fats, such as vegetable oil / sunflower oil / olive oil / corn oil / lard / oil (usually used in deep frying).
Each fire extinguisher is designed to effectively extinguish the fire and its contents. Each fire extinguisher has different equipment that is suitable for fighting certain types of fire. The right fire extinguisher must be used for a specific fire class, otherwise it will not be able to fight the fire and sometimes it can increase the fire.
Types of extinguishers can be easily identified by their colors, plates and names. It is very easy to tell them apart.
F Class Extinguishers
Water extinguishers are in red and the word “water” will be printed in white text. It is an old method that provides water at high velocity for fire fighting.
This is suitable for class A fires: ie. fire retardants in coal, plastic, paper, textiles and related materials.
The water spray will be red in color and the word “aqua spray” will be printed in white on it. These are better than traditional water models for firefighting because they spray water over a larger area at a higher pressure. Like their traditional counterparts, they are only suitable for Class A fires.
Water and water are some of the additives that increase the extinguishing capacity by up to 300%.

Chemicals have the ability to remove surface water pollutants effectively.
Water extinguishers are a special type of fire extinguisher that can put out all types of fires and can also fight Class F fires, which are more difficult to fight.
This type of fire extinguisher has a special nozzle that turns the “dry” water into small particles that are eventually drawn to the fire, cooled and ventilated, thus effectively extinguishing the fire.
It is a good fire extinguisher because it creates a safety barrier between the fire and the user, because it repels the heat and leaves no problem to clean the residue.

These types of extinguishers may not be suitable for electrical fires, but when used in electrical accidents, they are less dangerous than conventional water extinguishers.
ABC fire extinguishers will be printed as “powder” above the blue rectangle, below the rectangle will be written as “ABC powder”. As the name suggests, these are designed to extinguish class – A, B, C containing strong flames/water/gas.
Since it is not active in nature, it is suitable for extinguishing electrical fires, but it cannot easily penetrate the room so that the fire can be re-ignited.
This also leaves a residue that will be difficult to clean and can damage electronics, carpets, furniture and more.
What Is A Class D Fire Extinguisher?
This type of fire is rarely seen anywhere. They have the word “powder” printed in white text in a blue rectangle. But they should not be confused with ABC powder extinguishers and they will show M28 or L2 below the rectangle.
M28 and L2 are special types of fire extinguishers designed to withstand Class D fires, with combustible materials in the form of powder or chips. These contain lithium, sodium, aluminum or magnesium.
Example: This fire extinguisher has a low speed to ensure that L2 or M28 powder is applied slowly and carefully to the burning material to avoid excessive spread.
When this type of fire extinguisher is first activated, it forms a layer of insulation and protects the metal from penetrating and other combustible materials and cools the fire by preventing oxygen from reacting with the metal.
Fire Extinguishers And It’s Types
L2 is suitable for all types of metal fires, but M28 fires cannot be used for lithium. (Easy trick to remember: that L2 has L – “L” stands for Lithium.)
CAUTION: Never use this on a fire, especially an electrical fire, and remember that water should not come into contact with flammable materials.
Proper training is required to use the M28 and L2 extinguishers as the method of use is completely different compared to other extinguishers.
Foam extinguishers can be identified by seeing the word “foam” written on top of the cream rectangle in their body.
Understanding The Fire Extinguisher Types By Colors
It is mainly a water-based foam that has a flame-retardant effect on the floor as well as a covering effect. It cools the fire and seals the gas, preventing it from burning again.
When this is used against a class A fire, the user can only point at it and throw it, if it is used for a class B fire it must not be thrown into the fire water. This can cause the fire to spread. It is recommended to spray the foam around where it can collect and flow over it.
NOTE: Foam extinguishers should not be used on sawdust/grease fires. It should also not be used for electrical purposes, but accidental spills are less harmful than water.
CO2 eruptions are indicated by “CO2” written in white on four black sides. These also have different types of hoses.

An electrical fire and a type B fire can extinguish carbon dioxide; they burn by displacing oxygen from the air. As they leave nothing behind like other types of fire extinguishers, they are actually used in workshops/offices/where there is a possibility of an electrical fire which can reduce the damage to the equipment.
NOTE: CO2 extinguishers should not be used on fires F. A strong jet from the extinguisher will throw burning grease onto the fryer and cause the fire to spread to the surrounding area. Remember that carbon dioxide has already ignited a fire, and if the gas flows away, the fire can reignite if there is no source of fire.
Only carbon dioxide with cold horn should be used. Or the hand holding the horn may change as the gas cools as it exits
Chemical extinguishers can be identified by the word printed above the yellow rectangle as “wet chemical”, and have a wide range of uses.
Types Of Fires And Fire Extinguishers
These are designed to extinguish class F fires; they are very useful because they are able to spread the fire with high temperature: like oil and cooking oil etc.
The chemicals in the container give off heat, cool the burning material and act as a soap that seals the surface of the fire and repels the fire.
They produce very fine, light sprays such as L2 and M28 extinguishing powders to prevent burning oil/grease from spilling onto the user or spreading around.
The best way to do this is to rotate it slowly. The individual must remove all objects from burning oil or grease or the fire will reignite.
Fire Extinguisher Types And Uses
NOTE: This type is not suitable for Class B fires (containing water) and can fight Class A fires, but is not as effective as other extinguishers.
The fireplace is also available with a metallic/aluminium/silver finish. These fire extinguishers are suitable for clean areas where there is a risk of damage, or for furnishing etc.
If you are putting out a fire in your area, always refer to the manufacturer’s instructions for use. It should only be used on small fires (no bigger than a dustbin) and by someone who is safe and able to use a fire extinguisher.
One pound (1 kg) of dry powder is recommended for home use. If the fire cannot be extinguished with a 1 kg fire extinguisher, it is too big. You must evacuate everyone from the home and call 000.

The kitchen is where the fire starts in the house. Fire extinguishers and fire extinguishers should be placed near the kitchen entrance or exit to provide an escape route if you cannot put out the fire.
In cars, caravans or boats, fire extinguishers should be placed near the exit where they can be easily reached and used without exposing yourself to fire. You
