What Is a Fire Extinguisher?
A fire extinguisher is a device used to put out fires. It is usually portable and made of metal or plastic with an internal mechanism that contains pressurized carbon dioxide, water, foam, or dry chemicals. When there’s a fire, your first impulse should be to call the fire department. You can also put out small fires with a portable fire extinguisher, but you should only use it if you know how to use it.

What Are the Components?
Some fire extinguishers may contain a carbon dioxide (CO2) extinguisher, which is a dry-powder extinguisher. Others may have sodium bicarbonate, while other fire extinguishers may contain sodium carbonate and a flask of acid.
History of Fire Extinguishers
Captain George William Manby invented the first fire extinguisher in 1818, and it worked by expelling a stream of water onto the flames. It was constructed from a copper cylinder with a plunger at one end and a hose nozzle.
The cylinder was put into a chemical solution called “extinguishing liquid” (potassium carbonate, sodium bicarbonate, and water). The pressure created when you pumped the handle forced the chemicals out.
Are There Different Types of Fire Extinguishers?
Yes, there are five types of fire extinguishers:
- Water fire extinguishers.
- Foam fire extinguishers.
- Powder fire extinguishers.
- Wet fire extinguishers.
- Carbon dioxide (CO2) extinguishers.
Water Fire Extinguishers
First, we’ll look at water fire extinguishers, which are the most common and cheapest to use. Water fire extinguishers are devices used to put out different types of fires, especially combustible liquids. Water-based solutions effectively put out these fires because the water molecules soak into the fuel and cause it to lose its explosive properties.
Foam Fire Extinguishers
Secondly, foam fire extinguishers work the same way as water, but instead of just cooling it, they smother it with foam that dries hard when released. The foam is produced from a combination of water and a foaming agent, which produces a dense white foam that coats the fuel source and surrounding area, preventing oxygen from reaching the fuel. This prevents re-ignition once the flame has been extinguished.
Powder Fire Extinguisher
Thirdly, is the powder extinguishers. A powder fire extinguisher uses dry chemicals to put off Class D fires fueled by flammable metals, such as magnesium and potassium. Class D fires are also called “white-hot” fires because they produce very high temperatures that can melt or deform the metal.
Staying ahead of the requirements for safety inspections without proper tools takes plenty of time and effort. Flexible rules, pre-configured and custom inspections and powerful automations ensure a flawless operation of your assets.
Wet Chemical Fire Extinguishers
Then we have the wet chemical fire extinguishers. Wet chemical fire extinguishers are a type of fire extinguisher that works using water and potassium-based chemicals. These chemicals mix to form a thick white foam when they come into contact with flames or hot surfaces, which smothers the fire and prevents it from burning any further.
This fire suppression agent is especially useful for fighting Class B fires like paper, wood, plastics, or electrical materials. This is because these fires require large amounts of water to put them off.
Carbon Dioxide (CO2) Extinguishers
Last on the list is the carbon dioxide (CO2) extinguishers. When a fire occurs, You can use CO2 extinguishers to turn it into a smothering fire. There are four different types of CO2 extinguishers: solid stream, cone, fog, and multi-purpose. They can be used on all types of fires, except for electrical fires. The main benefit of using these is that they do not leave any residue or toxic gases after use, making them okay to use in most environments.
All these types of fire extinguishers inter-change roles in case of a fire outbreak. Later on, we will be discussing the different types of roles each type of extinguisher play in case of a fire outbreak.
What Are the Different Fire Classes?
For one to be able to point out what type of fire extinguisher serves the best purpose in eradicating fires, there is a major factor that one has to consider; the cause of fire or what is burning. Let’s jump right into that list.
Class A
Class A fires are those that burn solid fuel, such as wood, paper, or plastic. They have a high potential to spread and cause injuries. Class A fires can also cause a lot of damage to property. If you’ve ever seen a fire in the movies, it’s probably been a Class A fire.
Class B
These type of fires are caused by flammable liquids, like diesel, paint, or petroleum oil.
Class C
The most common type of fire extinguisher in the office is a class C. These work on electrical fires, such as those caused by overheated wires and circuits. The Class C is also good at putting out grease and oil-based fires, such as those created by burning food or paper covered in cooking grease. They also take out flammable gases like butane, propane, and overheated electrical equipment.
Class D
Class D fires are the most common type of fire encountered in industrial settings. The materials that commonly support class D fires are plastics, rubber, and paints. Class D fires always involve highly flammable metals like potassium, lithium, sodium, magnesium, and titanium. A common misconception about class D fires is that the presence of dirt or other solid material makes it safer to fight. In fact, the opposite is true.
Which Type of Fire Extinguisher to Use in Which Situation?
In the event of a fire emergency, it is important to know which type of fire extinguisher you need to use.
- Classification A: the ideal type of fire extinguisher to use is the water fire extinguisher.
- For class B fires, both the foam and powder fire extinguisher can be used effectively.
- Classification C fires: use the carbon dioxide (CO2) extinguishers and ABC powder extinguishers.
- For class D fires, one can make use of the M28 and L2 powder extinguishers.
Fire Extinguisher Inspection Requirements
If you were to ask someone what they think when they see a fire extinguisher, the answer is likely to be either “safety” or “fire”. However, if you ask them what comes to mind when they see a fire extinguisher that has not been inspected in years, the answer might be different.
Fire extinguishers are life-saving appliances that should be treated with respect. They are used to stop or suppress fire by removing heat from the fire through their chemical reaction, which disrupts the chain of events that leads to combustion. Fire extinguishers can be equipped with pressure gauges and strainers to prevent over-pressurization, but they require periodic maintenance to keep them in working order.
All fire extinguishers must be inspected annually by a competent person. This includes examining the operating instructions, pressure gauge, and discharge gauge for all types of portable fire extinguishers.
The competent person should also check that the extinguisher is visibly in good condition, not excessively dirty or oiled, that there are no signs of corrosion on the unit or its parts. The hose must be tight-fitting to the couplings and not damaged anywhere along its length. It must also have no holes.

You should know that an expired extinguisher is not necessarily ineffective. It can still fight a fire, but it may be less effective than one with the correct timestamp.
Check the pressure gauge on the side of your fire extinguisher to see if you need to recharge or refill your unit. If your gauge reads below 100 psi, you’ll likely need to have it recharged before using it again.
Who Can Carry Out a Fire Extinguisher Inspection?
All fire extinguishers must be regularly maintained and serviced. This is because a fire extinguisher can only be used once before requiring an inspection and service. If you don’t have your fire extinguishers checked on a regular basis, there is every chance they will fail to perform when you need them the most.
A professional fire safety and equipment company must test and certify your fire extinguisher once a year. Every six years, a comprehensive breakdown and internal inspection are required. It’s possible that you won’t require a professional to perform the monthly fire extinguisher inspection.
No one is authorized to conduct a fire extinguisher check-up routine or maintenance unless you are a legally registered fire extinguisher engineer under the law is to conduct such. Fire extinguishers are designed to be heavy, durable, and portable. They can’t operate effectively if they aren’t in good working order. For your safety and the safety of those around you, fire extinguishers must be inspected regularly, as a rule of thumb, at least once a year.
