Fire Extinguisher Definition
A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one that has reached the ceiling, endangers the user (i.e., no escape route, smoke, heat, explosion hazard, etc.), or otherwise requires the expertise of a fire brigade.
There are two main types of fire extinguishers: water and dry chemical. Water extinguishers work by cooling the fire, while dry chemical extinguishers work by interrupting the chemical reaction that fuels the fire.
Water extinguishers are the most common type of extinguisher and are suitable for use on most types of fire. They are not suitable for use on fires that involve electrical equipment, as the water can cause electrical shocks.
Dry chemical extinguishers are suitable for use on most types of fire, including those that involve electrical equipment. They work by interrupting the chemical reaction that fuels the fire.

What’s in a fire extinguisher?
A fire extinguisher is a device that is used to put out fires. The most common type of fire extinguisher is the water extinguisher, which is used to extinguish fires in homes and businesses. There are also chemical extinguishers, which are used to extinguish fires in industrial settings.
What are the 4 types of fire extinguishers?
There are four common types of fire extinguishers: water, foam, dry chemical, and carbon dioxide.
Water extinguishers are the most common type of extinguisher and are effective against fires involving organic materials such as paper, wood, and cloth. Foam extinguishers are effective against fires involving flammable liquids such as gasoline and oil. Dry chemical extinguishers are effective against fires involving combustible metals such as magnesium and aluminum. Carbon dioxide extinguishers are effective against fires involving electrical equipment.
What is the importance of fire extinguisher?
Fire extinguishers are an important part of any fire safety plan. They can help put out small fires before they get out of control, and can also help protect you from the smoke and heat of a larger fire.
What are the 5 types of fire extinguishers used for?
There are five types of fire extinguishers that are most commonly used: water, foam, dry chemical, carbon dioxide, and Halon.
Water extinguishers are the most common type of fire extinguisher and can be used on all types of fires, except for grease and electrical fires. The water extinguisher works by cooling the fire and taking away the heat that is fueling the fire.
Foam extinguishers are also very common and can be used on all types of fires, except for electrical fires. The foam extinguisher works by smothering the fire and creating a barrier between the oxygen and the fuel.
Dry chemical extinguishers are also common and can be used on all types of fires, except for electrical fires. The dry chemical extinguisher works by interrupting the chemical reaction that is taking place between the fuel and the oxygen.
Carbon dioxide extinguishers are less common, but can be used on all types of fires, except for electrical fires. The carbon dioxide extinguisher works by displacing the oxygen that is fueling the fire.
Halon extinguishers are the least common type of fire extinguisher, but can be used on all types of fires, including electrical fires. The Halon extinguisher works by interrupting the chemical reaction that is taking place between the fuel and the oxygen.
What are the 7 parts of a fire extinguisher?
- The fire extinguisher handle is used to grip the extinguisher and is also used to operate the extinguishing mechanism.
- The fire extinguisher body is made of metal and contains the fire extinguishing agent.
- The fire extinguisher nozzle is used to direct the flow of the extinguishing agent.
- The fire extinguisher pin is used to secure the handle in the upright position and prevents accidental discharge of the extinguisher.
- The fire extinguisher valve is used to control the flow of extinguishing agent from the extinguisher.
- The fire extinguisher gauge is used to indicate the amount of extinguishing agent remaining in the extinguisher.
- The fire extinguisher hose is used to direct the flow of extinguishing agent to the fire.
Why CO2 is used in fire extinguisher?
Carbon dioxide (CO2) extinguishers work by displacing the oxygen in the air. A fire needs oxygen to continue burning, so by depriving the fire of oxygen, the fire is extinguished.
CO2 is also effective at smothering the fire, as it prevents oxygen from getting to the fire. This is why CO2 extinguishers are often used on electrical fires, as they will not conduct electricity.
What are the 4 steps in using a fire extinguisher?
- Pull the pin at the top of the fire extinguisher. This will break the seal and allow you to discharge the extinguisher.
- Aim the nozzle of the fire extinguisher at the base of the fire.
- Squeeze the lever slowly and evenly.
- Sweep the nozzle from side to side at the base of the fire until it is extinguished.
What are the 7 types of fire?
- Class A fires are the most common and are fueled by solid materials, such as wood, paper, or fabric.
- Class B fires are fueled by flammable liquids, such as gasoline, oil, or paint.
- Class C fires are fueled by electrical equipment, such as appliances, wiring, or batteries.
- Class D fires are fueled by metals, such as aluminum, magnesium, or potassium.
- Class K fires are fueled by cooking oils, such as vegetable oil or grease.
- Wildland fires are those that occur in natural areas, such as forests or grasslands.
- Structure fires are those that occur in buildings or other man-made structures.
What is importance of fire safety?
The importance of fire safety cannot be understated. Fire safety is important for a number of reasons. First and foremost, fire safety helps to protect people and property from the devastation that a fire can cause. Secondly, fire safety helps to ensure that a fire does not start in the first place. And finally, fire safety helps to ensure that a fire is quickly detected and extinguished if it does occur.
Who should use an extinguisher?
There is no one definitive answer to this question as it depends on the specific circumstances and situation. However, in general, anyone who is responsible for the safety of others (such as in a workplace or public setting) or who is likely to be near a fire should be trained in how to use an extinguisher.
Final Talk
A fire extinguisher is a device that is used to put out fires. It is usually a handheld device that is filled with a extinguishing agent.
