ABC Fire Extinguisher And Their Uses

We all know that every place, whether it’s your home, workplace, or any public place, require to have fire extinguishers just to prevent any kind of fire hazard. However, most of us even don’t know that a single fire extinguisher does not work on all types of fire.

There are many different types of fire extinguishers available to fight with many different classes of fire. Hence, we first of all need to ensure that we have the proper extinguisher installed appropriately for the potential fire hazards for your building for achieving true safety. ABC Fire Extinguisher is one of the most well-known yet very versatile kinds of extinguishers available in the market.

There are five basic classifications of fuel that exist in this sphere. And, the extinguishers are considered with either letter-shaped or pictorial symbols, which specify what types of fires they are proposed for.

Have a look at the classifications of Fires and Extinguishers!

Class A: This category of fire involves ordinary combustible materials, such as cloth, wood, paper, rubber, and a lot of plastics. Extinguishers with an A rating are considered to extinguish fires involving these combustible materials.

Class B: This type of fire involves flammable and combustible liquids such as gasoline, alcohol, oil-based paints, and lacquers. Extinguishers with a B rating are intended to extinguish fires involving flammable and combustible liquids.

Class C: Class C type fire comprises energized electrical equipment such as computers, TV, AC, refrigerator, and many more. Extinguishers with a C rating are aimed for use with fires involving energized electrical apparatus.

Class D: Fire implicates combustible metals, such as magnesium, titanium, and sodium. Fire Extinguishers with a D rating is intended to extinguish fires involving combustible or flammable metals.

Class K: class K's kind of fire involves vegetable oils, animal oils, or fats in cooking appliances. And, the extinguishers with a K rating are made available to extinguish fires involving these cooking resources utilized, especially in commercial cooking appliances.

ABC Fire Extinguisher & its usage

ABC Fire Extinguisher is the ideal choice for many people as it can put out many different types of fires. They use a dry chemical like mono ammonium phosphate (pale yellow color), which is capable of putting out all three classes of fire quickly. As the ABC type extinguisher uses a dry chemical that again helps to cool down the fire immediately- leaves a residue once the fire has been put out hence, keep this fact in mind when choosing this type of extinguisher. The ABC type fire extinguishers come in different sizes and capacities and those are made for both commercial and non-commercial use. Moreover, ABC rated fire extinguishers are also known as multipurpose extinguishers and rated for use with more than one classification of fire.

What is an ABC fire extinguisher used for? ABC fire extinguisher is used to put out the fire (class A, B, C) by coating the fuel with a thin layer of dry chemical as dust for separating the fuel. These types of extinguishers are extremely effective in putting out the fire as the powder works to interrupt the chemical reaction of the fire. ABC fire extinguishers are used in a variety of locations, be it a new building, public hallway, laboratory, mechanical room, break room, chemical storage area, or office.

Composition and Types of ABC Fire Extinguishers

ABC fire extinguishers contain monoammonium phosphate, a dry chemical agent that is effective in extinguishing different types of fires. The extinguishing agent is stored under pressure in a metal canister, ready for immediate deployment.

Monoammonium Phosphate

Monoammonium phosphate is a yellow powder that can effectively smother fires by interrupting the chemical reactions that sustain combustion. When discharged, it forms a barrier between the fuel and the oxygen in the air, effectively suffocating the fire.

Types of ABC Fire Extinguishers

There are several types of ABC fire extinguishers based on their size, construction, and mode of operation:

• Portable ABC Fire Extinguishers: These are the most common type, available in various sizes from 1 to 20 pounds. They are designed for ease of use and portability, making them suitable for homes, offices, and vehicles.
• Wheeled ABC Fire Extinguishers: Larger and more robust, these extinguishers are mounted on wheels for easy mobility. They are typically used in industrial settings where larger fires may occur.
• Stored Pressure ABC Fire Extinguishers: In these extinguishers, the propellant and extinguishing agent are stored in a single container. They are easy to maintain and use.
• Cartridge-Operated ABC Fire Extinguishers: These have a separate cartridge of compressed gas that activates the extinguisher. They are often preferred in environments where regular maintenance checks are more feasible.

How ABC Fire Extinguishers Work

Understanding the operation of ABC fire extinguishers is crucial for their effective use in fire emergencies.

Activation Mechanism

Most ABC fire extinguishers operate using the PASS method:

• P (Pull): Pull the pin located at the top of the extinguisher. This pin prevents accidental discharge and must be removed to activate the extinguisher.
• A (Aim): Aim the nozzle or hose at the base of the fire. Targeting the base is essential for effectively cutting off the fire's fuel source.
• S (Squeeze): Squeeze the handle or lever to release the extinguishing agent. The pressure from the propellant forces the agent out of the nozzle.
• S (Sweep): Sweep the nozzle from side to side at the base of the fire until it is extinguished. Continue to apply the agent until the fire is completely out.

Discharge and Coverage

When the handle is squeezed, the monoammonium phosphate powder is expelled forcefully from the nozzle, covering the fire with a fine layer of powder. This powder forms a barrier between the fuel and the air, effectively smothering the flames. The discharge time and coverage area depend on the size of the extinguisher, with larger units providing more extensive coverage.

Benefits of ABC Fire Extinguishers

ABC fire extinguishers offer numerous benefits, making them a preferred choice for many settings.
