Fire extinguishers are commonplace in offices, shopping malls, and residential communities. Medium to large-sized fire extinguishers installed in such locations ensure the safety of people in the event of a fire. People gradually realize the value of installing these at home. There are various types and sizes of fire extinguishers on the market to meet different needs and budgets. The cost of a fire extinguisher varies depending on the type, but the method of operation is essentially the same. The majority of these are simple to use. A brief demonstration is sufficient to grasp their functionality. In this blog, we will get guidance about Fire Extinguisher for Home – Types of Fire Extinguishers, How to Use & More.
1. Water Extinguishers
Water extinguishers are classified into two categories. There are two types of extinguishers: standard water extinguishers and dry water extinguishers. Let us quickly examine what each of these has to offer:
- Standard Water Extinguishers
This type of extinguisher uses high pressure to dispense water. It may even contain chemicals that improve its ability to extinguish fires. It aids in the extinguishment of flames caused by class A fires. This includes fires started by combustible materials like paper, cardboard, plastic, wood, fabric, and other solid materials.
The word ‘water’ or ‘aqua spray’ is boldly imprinted on it. The extinguisher is a bright red colour. Spraying it on electrical appliances and oil fires must be strictly prohibited.
- Dry Water Mist Extinguisher
This is one of the most useful fire extinguishers because it can extinguish almost any fire. Even the most difficult fires can be put out with their assistance. As it exits the nozzle, water is converted into dry microscopic particles. These particles suffocate the flames.
This type of extinguisher is also completely red. The words ‘water mist’ will be imprinted on it.
2. Wet Chemical Extinguishers
Cooking oils and fats, for example, are designed to extinguish class F fires. They extinguish extremely hot fires by lowering their temperature. It sprays a soapy solution that, by sealing the surface, prevents the fire from re-igniting. Spraying the solution slowly in a circular motion is recommended for best results. The fire may re-ignite if not properly extinguished. It comes with a long hose that makes it easier to fight fires. It can also be used on class A fires, though its effectiveness may be limited.
This extinguisher should not be used for fires involving class B liquids. The words “wet chemical” are imprinted on these fire extinguishers.
3. Powder Extinguisher
Powder extinguishers are further divided into three types: ABC, L2, and M28. Let’s take a closer look at each type:
- ABC Powder
This type of extinguisher uses powder to create a thermal blast. The powder contains ingredients that instantly cool down the flames. It fights fires of the A, B, and C classifications. This means you can use this extinguisher to extinguish fires involving solids, liquids, and gases. Because it is non-conductive, it is suitable for fighting electrical fires. It should not, however, be used on class F fires, such as those caused by fat or cooking oil. Using these extinguishers in confined spaces is also not recommended because they are harmful if inhaled.
The words ‘powder’ and ‘ABC powder’ are imprinted on this type of fire extinguisher.
- L2 Powder
These extinguishers are commonly found near engineering plants. They are distinguished from ABC powder extinguishers by a special hose. They aid in extinguishing fires involving combustible metals such as lithium, sodium, and magnesium. It is classified as a D fire. It is ineffective against any other type of fire. It should be kept away from electrical appliance fires in particular.
- M28 Powder
It has properties similar to L2 powder. It is also intended to put out fires involving combustible metals. However, lithium should not be used on lithium because the reaction can be fatal, as well as electrical fires.
4. Carbon Dioxide Extinguisher
CO2 has been designed as a fire extinguisher to combat fires involving flammable liquids. They are used to extinguish electrical fires and fight class B fires. They displace the oxygen present in the environment to extinguish the flames. Their use on fires caused by hot cooking oil and fat should be strictly prohibited. It can spread the blaze and cause damage when used on class F fires.
The hose on such devices is not like that of other types of fire extinguishers. The best part is that there is no residue left behind. As a result, their use does not harm the environment or the equipment. However, it must be used with caution or you may end up causing harm to your hands.
‘Carbon dioxide’ or ‘CO2’ is imprinted on these appliances.
5. Foam Extinguisher
Water and a foaming agent make up foam extinguishers. It is intended for use in fighting class A and B fires. It quickly extinguishes the fire by creating a blanketing effect. The vapours are sealed to prevent the fire from rekindling. However, the method for using this type of extinguisher on class A and class B fires varies. It is critical to read the instructions to use them correctly and carefully. These are not intended for use on any other type of fire. Their use in electrical and fat-pan fires must be strictly prohibited.
This type of fire extinguisher has the word “foam” imprinted on it.
Classification of Fire
This blog is about Fire Extinguisher for Home – Types of Fire Extinguishers, How to Use & More. The following is how fire has been classified into various groups:
- Class A comprises combustible carbon-based solids like wood, paper, and cloth.
- Class B – Inflammable liquids such as petrol, diesel, gasoline, turpentine, and oils are classified as Class B. However, cooking oil is not included in this category.
- Class C- Fires caused by combustible gases such as methane, propane, and butane are classified as Class C.
- Class D – Entails the combustion of metals such as lithium, magnesium, and aluminium.
- Electrical Fire -Faulty electrical appliances cause electrical fires. The electric spark symbol represents it.
- Class F – Fats and cooking oils are to blame for this.
How to Use a Fire Extinguisher?
It is critical to seek professional training before using a fire extinguisher. We’ve provided a brief overview of how such appliances are used. Here is Fire Extinguisher for Home – Types of Fire Extinguishers, How to Use & More.

Step 4
Sweep the extinguisher at the base of the fire from side to side until the fire is extinguished.
Conclusion to Fire extinguishers for home
Various fire extinguishers have been developed to combat different types of fire. Some are water-based, mist-based, chemical-based, carbon dioxide, wet chemical, powder, and foam extinguishers. Before purchasing a fire extinguisher, it is critical to understand which type should be used in which situation. Extinguisher usage must also be learned to use them effectively during an emergency. If you use it, get a fire extinguisher refill to prepare it for future use.
