Water extinguisher

It works by cooling the fire and preventing it from spreading. But they are not effective in all types of fires. For example, water extinguishers will not put out fires caused by flammable liquids or electrical equipment.

Foam extinguishing agent

Foam extinguisher

It works by smothering the fire and preventing it from getting oxygen. They are effective on most types of fires, including flammable liquid fires. But foam extinguishers can be heavy and difficult to use.

Dry chemical extinguishing agent

Dry chemical extinguisher

It works by interrupting the chemical reaction that causes the fire. They are effective on most types of fires, including those caused by flammable liquids. But dry chemical extinguishers can be messy and difficult to clean up.

Carbon dioxide extinguishing agent

Carbon dioxide extinguisher

It works by displacing the oxygen that fuels the fire. They are effective on most types of fires, including those caused by flammable liquids. But carbon dioxide extinguishers can be expensive and difficult to use.

What’s the most effective fire extinguisher on a class b fire and a class c fire?

Different Types of Fires

There are different extinguishers for different types of fires. Class B fires are best extinguished with a CO₂ fire extinguisher, while Class C fires require an ABC dry chemical fire extinguisher.

Check the label to ensure it is the right fire extinguisher for the type of fire you are trying.

Different Capabilities

Different fire extinguishers also have other capabilities. For example, a CO₂ extinguisher is only effective at short range, while an ABC dry chemical fire extinguisher can be used at long range.

Additional Tips in Choosing the Right Fire Extinguishers

Remember a few more when selecting fire extinguishers for your home or business. The size and type of fire extinguisher you need depends on the combustible materials in the area where it will be used.

Other Types of Fire Extinguishers

Wet chemical extinguishers are a type of extinguisher that uses aqueous-based or water-based solutions to extinguish fires.

The solution in the extinguisher breaks the chemical reaction of the fire and cools the burning surface, making it difficult for the fire to reignite.

Wet chemical extinguishers are most effective on Class A and Class F fires but can also be used on Class B and Class C fires.

For example, Class A fires involve ordinary combustibles such as paper, wood, cloth, and rubber. The best extinguisher for Class A fires is water or a foam-based extinguisher. Class B is the fires involving flammable liquids such as gasoline, oils, paint thinners, and propane. The best type of fire extinguisher for Class B fires is a CO_ based extinguisher.

Class C fires involve electrical equipment, such as appliances, wiring, and circuit breakers. The best type of fire extinguisher for Class C fires is a CO_ based extinguisher.

Class D fires involve combustible metals, such as aluminum, magnesium, and titanium. The best type of fire extinguisher for Class D fires is a powder-based extinguisher.

Class K fires involve cooking oils and fats. The best type of fire extinguisher for Class K fires is a foam-based extinguisher.

When selecting a fire extinguisher, you should also consider the environment in which it will be used. For example, if the fire extinguisher will be used in a kitchen, it should be designed for use with cooking oils and fats.

Size of Fire Extinguishers
