A fire extinguisher is a portable device that is used to extinguish or control small fires. It typically contains an agent that can extinguish the fire, such as water, foam, or a dry powder.Fire extinguishers are typically found in buildings, vehicles, and other locations where fires may occur, and they are often required by law in certain situations.There are different types of fire extinguishers for different types of fires, such as Class A for ordinary combustibles, Class B for flammable liquids, and Class C for electrical equipment.
Types of Fire Extinguisher :-
There are several different types of fire extinguishers, each designed to be used on specific types of fires.NFPA Standard 10 Says about the types of Fire Extinguisher and Indian Standard code IS 15683 also explains about this.The most common types include:
Water: These extinguishers are used on Class A fires, which involve ordinary combustibles such as wood, paper, and cloth.
Foam: These extinguishers are used on Class A and B fires, which involve flammable liquids such as gasoline and oil.
Dry chemical: These extinguishers are used on Class B and C fires, which involve flammable liquids and electrical equipment. They work by creating a barrier between the oxygen in the air and the fuel source, suffocating the fire.
Carbon dioxide: These extinguishers are used on Class B and C fires, which involve flammable liquids and electrical equipment. They work by removing the oxygen that the fire needs to survive.
