A fire extinguisher is a crucial safety item meant to suppress and control fires in their early stages, preventing potentially devastating fire accidents from escalating. These portable devices are designed to emit fire-fighting compounds that disrupt the combustion process, restrict oxygen availability, or cool down the burning materials, thus extinguishing the flames. Fire extinguishers serve an important role in protecting lives, property, and the environment by allowing people to fight fires before they become uncontrollable. The main concept underlying fire extinguishers is their ability to combat several types of fires, each of which is classified based on the type of materials or substances engaged in the combustion process. Class A (common combustibles such as wood, paper, and cloth), Class B (flammable liquids and gases), Class C (electrical fires), Class D (flammable metals), and Class K (cooking oils and fats) are the different types of fires. Fire extinguishers are purpose-built to target one or more of these classes, ensuring their effectiveness and safety in a variety of fire circumstances.

Fire extinguishers are classified into two types: stored-pressure and cartridge-operated. The expellant is held in the same compartment as the firefighting agent in stored pressure units. Different propellants are utilized depending on the agent. Nitrogen is commonly used in dry chemical extinguishers, whereas air is commonly utilized in wet and foam extinguishers. The most popular form is stored-pressure fire extinguishers. Cartridge-operated fire extinguishers use a separate cartridge to deliver the propellant gas into the extinguishing agent when activated. These extinguishers are less prevalent and are mostly utilized in industrial environments with high consumption rates.

There are several types of fire extinguishers available, each with a unique extinguishing agent designed to tackle specific fire classes:

a) Water Extinguishers: These extinguishers deploy water to cool down the fire and lower its temperature, effectively suppressing Class A fires involving materials like wood, paper, and cloth.

b) Foam Extinguishers: Foam extinguishers release a foam solution that creates a barrier, preventing the release of flammable vapors and suppressing both Class A and Class B fires.

c) Dry Powder Extinguishers: Dry powder extinguishers use fine powder to interrupt the chemical reaction between fuel and oxygen, making them suitable for Class A, B, and C fires.

d) Carbon Dioxide (CO2) Extinguishers: CO2 extinguishers discharge carbon dioxide gas, displacing oxygen and suffocating the fire. They are effective on Class B, C, and electrical fires.

e) Wet Chemical Extinguishers: These extinguishers release a fine mist that cools the fire and creates a soapy layer to suppress flammable vapors, making them ideal for Class K fires involving cooking oils and fats.

f) Clean Agent Extinguishers: Clean agent extinguishers utilize substances like Halon or Halotron to extinguish fires without leaving residue. They are versatile and suitable for Class A, B, and C electrical fires.

g) Water Mist Extinguishers: Water mist extinguishers emit a fine mist of water droplets to cool the fire and reduce available oxygen. They are effective for Class A and C fires.
